2. QUESTION NO: 1 In newer vehicles with air brakes, you put on the parking brakes using a __________-shaped, yellow, push-pull control knob. A. round B. diamond C. octagon D. oval MR CERTIFY Answer: B Explanation: In newer vehicles with air brakes, you put on the parking brakes using a diamond-shaped, yellow, push-pull control knob. You pull the knob out to put the parking brakes (spring brakes) on, and push it in to release them. On older vehicles, the parking brakes may be controlled by a lever. Use the parking brakes whenever you park. QUESTION NO: 2 Wedge brakes __________ A. are self-adjusting. B. require manual adjustment. C. do not require adjustment. D. either A or B Answer: D Explanation: With wedge brakes, the brake chamber push rod pushes a wedge directly between the ends of two brake shoes. This shoves them apart and against the inside of the brake drum. Wedge brakes may have a single brake chamber, or two brake chambers, pushing wedges in at both ends of the brake shoes. Wedge type brakes may be self-adjusting or may require manual adjustment. Wedge brakes are less common than s-cam brakes.

B. applies and releases the parking brakes when you use the parking brake control. C. applies and releases the brakes when you use the brake pedal during normal driving. D. none of the above Answer: B Explanation: Air brakes use compressed air to make the brakes work. Air brakes are a good and safe way of stopping large and heavy vehicles, but the brakes must be well maintained and used properly. Air brakes are really three different braking systems: service brake, parking brake, and emergency brake. The parking brake system applies and releases the parking brakes when you use the parking brake control. Pass Your Exam Guaranteed!

4. Mr Certify Idaho CDL Practice Tests QUESTION NO: 4 When you are testing the air leakage rate, you should apply __________ psi or more with the brake pedal after the initial air drop. A. 80 B. 90 C. 100 D. none of the above MR CERTIFY Answer: B Explanation: If you drive a vehicle with air brakes, you should conduct a final air brake check instead of a hydraulic brake check during step seven of the Seven-step Inspection Method. Test the air leakage rate. With a fully-charged air system (typically 125 psi), turn off the engine, release the parking brake, and time the air pressure drop. The loss rate should be less than two psi in one minute for single vehicles and less than three psi in one minute for combination vehicles. Then apply 90 psi or more with the brake pedal. After the initial pressure drop, if the air pressure falls more than three psi in one minute for single vehicles (more than four psi for combination vehicles), the air loss rate is too much. Check for air leaks and fix the problem before driving the vehicle. Otherwise, you could lose your brakes while driving. QUESTION NO: 5 Which of the following statements is true? A. When only the tractor has ABS, you should be able to maintain steering control, but there is greater risk of jackknifing. B. Having ABS on only the tractor, only the trailer, or even on only one axle, still gives you more control over the vehicle during braking. C. When only the trailer has ABS, the trailer is more likely to swing out. D. all of the above Answer: B Explanation: When you brake hard on slippery surfaces in a vehicle without ABS, your wheels may lock up. When your steering wheels lock up, you lose steering control. When your other wheels lock up, you may skid, jackknife, or even spin the vehicle. ABS helps you avoid wheel lock up. The computer senses impending lockup, reduces the braking pressure to a safe level, and you maintain control. You may or may not be able to stop faster with ABS, but you should be able to Pass Your Exam Guaranteed!

5. Mr Certify Idaho CDL Practice Tests steer around an obstacle while braking, and avoid skids caused by over braking. Having ABS on only the tractor, only the trailer, or even on only one axle, still gives you more control over the vehicle during braking. Brake normally. When only the tractor has ABS, you should be able to maintain steering control, and there is less chance of jackknifing. But, keep your eye on the trailer and let up on the brakes (if you can safely do so) if it begins to swing out. When only the trailer has ABS, the trailer is less likely to swing out, but if you lose steering control or start a tractor jackknife, let up on the brakes (if you can safely do so) until you gain control. When you drive a tractor-trailer combination with ABS, you should brake as you always have. In other words: -Use only the braking force necessary to stop safely and stay in control. -Brake the same way, regardless of whether you have ABS on the tractor, the trailer, or both. -As you slow down, monitor your tractor and trailer and back off the brakes (if it is safe to do so) to stay in control. There is only one exception to this procedure, if you always drive a straight truck or combination with working ABS on all axles, in an emergency stop, you can fully apply the brakes. Without ABS, you still have normal brake functions. Drive and brake as you always have. Remember, if your ABS malfunctions, you still have regular brakes. Drive normally, but get the system serviced soon. MR CERTIFY QUESTION NO: 6 When uncoupling, you should lower the landing gear before you __________ A. disconnect the air lines and electrical cable. B. chock the trailer wheels. C. position the rig. D. none of the above Answer: A Explanation: Knowing how to couple and uncouple correctly is basic to safe operation of combination vehicles. Coupling and uncoupling incorrectly can be very dangerous. General coupling and uncoupling steps can be helpful, but there are differences between different rigs. Learn the details of coupling and uncoupling the truck(s) you will operate. To uncouple safely, step one is to position the rig. Make sure the surface of the parking area can support the weight of the trailer. Have the tractor lined up with the trailer. (Pulling out at an angle can damage the landing gear.) Step two is to ease the pressure on the locking jaws. Shut off the trailer air supply to lock the trailer brakes. Ease pressure on the fifth wheel locking jaws by backing up gently. (This will help you release the fifth wheel locking lever.) Put the parking brakes on while the tractor is pushing against the kingpin. (This will hold the rig with the pressure off the locking jaws.) Pass Your Exam Guaranteed!

6. Mr Certify Idaho CDL Practice Tests Step three is to chock the trailer wheels if the trailer doesn't have spring brakes or if you're not sure. (If the trailer doesn't have spring brakes, the air could leak out of the trailer air tank, releasing its emergency brakes. Without chocks, the trailer could move.) The fourth step is to lower the landing gear. If the trailer is empty, lower the landing gear until it makes firm contact with the ground. If the trailer is loaded, after the landing gear makes firm contact with the ground, turn the crank in a low gear a few extra turns. This will lift some weight off the tractor. (Do not lift the trailer off the fifth wheel.) This will make it easier to unlatch the fifth wheel and it will make it easier to couple the next time. Step five is to disconnect the air lines and electrical cable. MR CERTIFY Disconnect the air lines from the trailer and connect the air glad hands to dummy couplers at the back of the cab or couple them together. Hang the electrical cable with the plug down to prevent moisture from entering it. Make sure the lines are supported so they won't be damaged while you are driving the tractor. QUESTION NO: 7 If you must back with a trailer on a curved path, back __________ A. toward the driver's side. B. in a straight line. C. toward the passenger's side. D. any of the above Answer: A Explanation: When backing a car, straight truck, or bus, you turn the top of the steering wheel in the direction you want to go. When backing a trailer, you turn the steering wheel in the opposite direction. Once the trailer starts to turn, you must turn the wheel the other way to follow the trailer. Whenever you back up with a trailer, try to position your vehicle so you can back in a straight line. If you must back on a curved path, back to the driver's side so you can see. Look at your line of travel before you begin. Get out and walk around the vehicle. Check your clearance to the sides and overhead, in and near the path your vehicle will take. Check the outside mirrors on both sides frequently. Get out of the vehicle and re-inspect your path if you are unsure. Back slowly. This will let you make corrections before you get too far off course. Correct drift immediately. As soon as you see the trailer getting off the proper path, correct it by turning the top of the steering wheel in the direction of the drift. When backing a trailer, make pull-ups to re-position your vehicle as needed Pass Your Exam Guaranteed!

7. Mr Certify Idaho CDL Practice Tests QUESTION NO: 8 To secure the tractor during the uncoupling process, apply the __________ brake and place the transmission in __________ A. parking, reverse. B. parking, neutral. C. service, neutral. D. service, reverse. MR CERTIFY Answer: B Explanation: Knowing how to couple and uncouple correctly is basic to safe operation of combination vehicles. Coupling and uncoupling incorrectly can be very dangerous. General coupling and uncoupling steps can be helpful, but there are differences between different rigs. Learn the details of coupling and uncoupling the truck(s) you will operate. To uncouple safely, step eight is to secure the tractor by applying the parking brake and placing the transmission in neutral. QUESTION NO: 9 In a trailer with no spring brakes, the __________ brakes will take over when the air stored in the trailer air tank is gone. A. service B. parking C. emergency D. none of the above Answer: C Explanation: Newer trailers have spring brakes just like trucks and truck tractors. However, converter dollies and trailers built before 1975 are not required to have spring brakes. Those that do not have spring brakes have emergency brakes which work from the air stored in the trailer air tank. The emergency brakes come on whenever air pressure in the emergency line is lost. These trailers have no parking brake. The emergency brakes come on whenever the air supply knob is pulled out or the trailer is disconnected. But the brakes will hold only as long as there is air pressure in the trailer air tank. Eventually, the air will leak away and then there will be no brakes. Therefore, it is very important for safety that you use wheel chocks when you park Pass Your Exam Guaranteed!

8. Mr Certify Idaho CDL Practice Tests trailers without spring brakes. A major leak in the emergency line will cause the tractor protection valve to close and the trailer emergency brakes to come on. You may not notice a major leak in the service line until you try to put the brakes on. Then, the air loss from the leak will lower the air tank pressure quickly. If it goes low enough, the trailer emergency brakes will come on. MR CERTIFY QUESTION NO: 10 Step two of coupling is to __________ A. inspect the fifth wheel. B. inspect the area and chock the wheels. C. secure the tractor. D. none of the above Answer: B Explanation: Knowing how to couple and uncouple correctly is basic to safe operation of combination vehicles. Coupling and uncoupling incorrectly can be very dangerous. General coupling and uncoupling steps can be helpful, but there are differences between different rigs. Learn the details of coupling and uncoupling the truck(s) you will operate. Step two is to inspect the area and chock the wheels. Make sure the area around the vehicle is clear. Be sure the trailer wheels are chocked or spring brakes are on. Make sure that any cargo is secured against movement due to the tractor being coupled to the trailer. QUESTION NO: 11 To check that air flows to all trailers during the pre-trip inspection, wait for air pressure to reach normal, then __________ A. push in the tractor protection valve control. B. pull out the tractor protection valve control. C. pull out the trailer air supply knob. D. push in the trailer air supply knob. Answer: D Explanation: Pass Your Exam Guaranteed!

9. Mr Certify Idaho CDL Practice Tests Check the brakes on a double or triple trailer as you would any combination vehicle. You must make additional checks on your double or triple trailers. To check that air flows to all trailers (double and triple trailers) during your pre-trip inspection, use the tractor parking brake and/or chock the wheels to hold the vehicle. Wait for the air pressure to reach normal, then push in the red "trailer air supply" knob. This will supply air to the emergency (supply) lines. Use the trailer handbrake to provide air to the service line. MR CERTIFY Go to the rear of the rig. Open the emergency line shut-off valve at the rear of the last trailer. You should hear air escaping, showing the entire system is charged. Close the emergency line valve. Open the service line valve to check that service pressure goes through all the trailers (this test assumes that the trailer handbrake or the service brake pedal is on), and then close the valve. If you do NOT hear air escaping from both lines, check that the shut-off valves on the trailer(s) and dolly(ies) are in the OPEN position. You MUST have air all the way to the back for all the brakes to work.

10. Mr Certify Idaho CDL Practice Tests A. couple the tractor to the first trailer. B. move the converter dolly into position and couple the first trailer to the second trailer using the method for coupling doubles. C. both A and B D. neither A nor B MR CERTIFY Answer: C Explanation: To couple the tractor/first semitrailer to the second/third trailers, first couple the tractor to the first trailer. Use the same method you would use for coupling tractor-semitrailers. Move the converter dolly into position and couple the first trailer to the second trailer using the method for coupling doubles. The triples rig is now complete. QUESTION NO: 13 To test the trailer emergency brakes during the pre-trip inspection, __________ A. charge the trailer air brake system, shut the engine off, and step on and off the brake pedal several times to reduce the air pressure in the tanks. B. pull out the trailer air supply control and pull gently on the trailer with the tractor. C. check for normal air pressure, release the parking brakes, move the vehicle forward slowly, and use the trolley valve. D. none of the above Answer: B Explanation: During the pre-trip inspection of your combination vehicle, test the trailer emergency brakes. Charge the trailer air brake system and make sure the trailer rolls freely. Then stop and pull out the trailer air supply control (also called the tractor protection valve control or the trailer emergency valve) or place it in the "emergency" position. Pull gently on the trailer with the tractor to be sure the trailer emergency brakes are on. QUESTION NO: 14 If the tractor protection valve doesn't work correctly, an air hose or trailer brake leak could drain all the air from the tractor, causing the __________ brakes to come on. A. service B. parking Pass Your Exam Guaranteed!

11. Mr Certify Idaho CDL Practice Tests C. emergency D. none of the above Answer: C Explanation: MR CERTIFY During your pre-trip inspection on a combination vehicle, test the tractor protection valve. Charge the trailer air brake system. (that is, build up normal air pressure and push the "air supply" knob in). Shut the engine off. Step on and off the brake pedal several times to reduce the air pressure in the tanks. The trailer air supply control (also called the tractor protection valve control) should pop out (or go from "normal" to "emergency" position) when the air pressure falls into the pressure range specified by the manufacturer. (Usually within the range of 20 to 45 psi). If the tractor protection valve doesn't work properly, an air hose or trailer brake leak could drain all the air from the tractor. This would cause the emergency brakes to come on, with possible loss of control. QUESTION NO: 15 To uncouple a converter dolly, release the pintle hook on the first semitrailer, then __________ A. apply the converter gear spring brakes or chock the wheels. B. slowly pull clear of the dolly. C. lower the dolly landing gear. D. disconnect the safety chains. Answer: B Explanation: To uncouple twin trailers, uncouple the converter dolly after uncoupling the rear trailer. Lower the dolly landing gear. Disconnect the safety chains. Apply the converter gear spring brakes or chock the wheels. Release the pintle hook on the first semi-trailer. Slowly pull clear of the dolly. Never unlock the pintle hook with the dolly still under the rear trailer. The dolly tow bar may fly up, possibly causing injury, and making it very difficult to re-couple.

Check the engine oil level, coolant level in radiator and condition of hoses, power steering fluid level and hose condition (if so equipped), windshield washer fluid level, battery fluid level, connections, and tie downs (the battery may be located elsewhere), and automatic transmission fluid level (which may require the engine to be running). Check the belts for tightness and excessive wear (alternator, water pump, and air compressor). Learn how much "give" the belts should have when adjusted correctly, and check each one. Check for leaks in the engine compartment (fuel, coolant, oil, power steering fluid, hydraulic fluid, and battery fluid) and look for cracked, worn electrical wiring insulation. Lower and secure hood, cab, or engine compartment door. QUESTION NO: 17 The combined strength of all cargo tiedowns must be enough to lift __________ times the weight of the piece of cargo tied down. A. one and one-half B. two C. two and one-half D. none of the above Answer: A Explanation: You must understand basic cargo safety rules to get a CDL. If you load cargo wrong or do not secure it, it can be a danger to others and yourself. On flatbed trailers or trailers without sides, cargo must be secured to keep it from shifting or falling off. In closed vans, tiedowns can also be important to prevent cargo shifting that may affect the handling of the vehicle. Tiedowns must be of the proper type and proper strength. The combined strength of all cargo tiedowns must be strong enough to lift one and one-half times the weight of the piece of cargo tied down. Proper tiedown equipment must be used, including ropes, straps, chains, and tensioning devices (winches, ratchets, clinching components). Tiedowns must be attached to the vehicle correctly (hooks, bolts, rails, rings). Cargo should have at least one tiedown for each ten feet of cargo. Make sure you have enough tiedowns to meet this need. No matter how small the cargo, it Pass Your Exam Guaranteed!

13. Mr Certify Idaho CDL Practice Tests should have at least two tiedowns. There are special requirements for securing various heavy pieces of metal.

B. you take your hands off the wheel. C. mental activities take your attention away from driving. D. any of the above Answer: D Explanation: Whenever you are driving a vehicle and your attention is not on the road, you're putting yourself, your passengers, other vehicles, and pedestrians in danger. Distracted driving can result when you perform any activity that may shift your full attention from the driving task. Taking your eyes off the road or hands off the steering wheel presents obvious driving risks. Mental activities that take your mind away from driving are just as dangerous. Your eyes can gaze at objects in the driving scene but fail to see them because your attention is distracted elsewhere. QUESTION NO: 19 Driving too fast reduces the time you have to react to an emergency and increases your __________ A. impact force. B. braking distance. C. both A and B D. none of the above Answer: C Explanation: Whenever you double your speed, it takes about four times as much distance to stop and your vehicle will have four times the destructive power if it crashes. High speeds increase stopping distances greatly. By slowing down a little, you can gain a lot in reduced braking distance. Pass Your Exam Guaranteed!

14. Mr Certify Idaho CDL Practice Tests QUESTION NO: 20 In the winter, pay extra attention to these items when conducting a pre-trip inspection: __________ A. tires, engine oil, engine belts, and hoses. B. tires, coolant level and antifreeze amount, tire chains, and lights and reflectors. C. tires, engine oil, windows and mirrors, and engine belts. D. engine oil, engine coolant, engine belts, and hoses. MR CERTIFY Answer: B Explanation: Make sure your vehicle is ready before driving in winter weather. Be sure you have enough tread on your tires. The drive tires must provide traction to push the rig over wet pavement and through snow. The steering tires must have traction to steer the vehicle. Enough tread is especially important in winter conditions. You must have at least 4/32 inch tread depth in every major groove on front tires and at least 2/32 inch on other tires. More would be better, Use a gauge to determine if you have enough tread for safe driving. Make sure the cooling system is full and that there is enough anti-freeze in the system to protect against freezing. This can be checked with a special coolant tester. You may find yourself in conditions where you can't drive without chains, even to get to a place of safety. Carry the right number of chains and extra cross links. Make sure they will fit your drive tires. Check the chains for broken hooks, worn or broken cross links, and bent or broken side chains. Learn how to put the hooks on before you need to do it in snow and ice. Make sure the lights and reflectors are clean. Lights and reflectors are especially important during bad weather. Check from time to time during bad weather to make sure that they are clean and working properly. QUESTION NO: 21 Ammonium nitrate, an oxidizer, is a Class __________ hazardous material.

A. Assign one student assistant to lead students to a "safe place" after evacuation. B. Teach at least a half dozen responsible, older students how to assist the other students off the bus during an evacuation. C. Evacuating the bus means that you must be prepared and plan ahead. D. none of the above Pass Your Exam Guaranteed!

21. Mr Certify Idaho CDL Practice Tests Answer: B Explanation: Evacuating the bus means that you must be prepared and plan ahead. When possible, assign two responsible, older student assistants to each emergency exit. Teach them how to assist the other students off the bus. Assign another student assistant to lead the students to a "safe place" after evacuation. However, you must recognize that there may not be older, responsible students on the bus at the time of the emergency. Therefore, emergency evacuation procedures must be explained to all students. MR CERTIFY This includes ensuring that they know the location of and operation of the various emergency exits and the importance of listening to and following all instructions given by you. Some tips to determine a safe place: -A safe place will be at least 100 feet off the road in the direction of oncoming traffic. This will keep the students from being hit by debris if another vehicle collides with the bus. -Lead students upwind of the bus if fire is present. -Lead students as far away from railroad tracks as possible and in the direction of any oncoming train. -Lead students upwind of the bus at least 300 feet if there is a risk from spilled hazardous materials. -If the bus is in the direct path of a sighted tornado and evacuation is ordered, escort students to a nearby ditch or culvert if shelter in a building is not readily available, and direct them to lie face down, hands covering their head. They should be far enough away so the bus cannot topple on them. Avoid areas that are subject to flash floods. QUESTION NO: 33 If you have no choice and you must back your bus, __________ A. back quickly and smoothly - the less time you spend backing, the better. B. and you must back-up at a student drop-off point, be sure to unload students before backing. C. and you must back-up at a student pick-up point, be sure to pick up students before backing. D. all of the above Answer: C Explanation: Backing a school bus is strongly discouraged. You should back your bus only when you have no other safe way to move the vehicle. You should never back a school bus when students are outside of the bus. Backing is dangerous and increases your risk of a collision. If you have no choice and you must back your bus, follow these procedures: -Post a lookout, preferably inside the school bus looking out the rear window. The purpose of the lookout is to warn you about obstacles, approaching persons, and other vehicles. The lookout Pass Your Exam Guaranteed!

22.
