These Questions Are From The Illinois CDL Manual
- None of these are correct
- Downshift once the RPM's become too high for the current gear
- Downshift before starting down the hill
- Downshift about half way down the hill
Quote From Page 25 Of The CDL Manual:
Slow down and shift down to a speed that you can control without using the brakes hard. Otherwise the brakes can overheat and lose their braking power. Downshift before starting down the hill. Make sure you are in a low enough gear, usually lower than the gear required to climb the same hill.
Quote From Page 2 Of The CDL Manual:
Indirect tiedowns create a downward force that increases the friction between the cargo and the deck. This increased friction restrains the cargo.
- An endorsement to drive school children in any vehicle for the sake of financial compensation
- An endorsement to drive a bus of school children to any location other than a public learning center
- An endorsement required to carry more than 10 passengers under the age of 12
- An endorsement to drive a yellow school bus designed to seat 16 or more persons, including the driver
Quote From Page 60 Of The CDL Manual:
A CDL holder wanting a School Bus Endorsement - An endorsement to drive a yellow school bus designed to seat 16 or more persons, including the driver - must first pass the knowledge exam (If your bus has air brakes, you also must pass the air brake exam). You must pass the skills and driving exams in the school bus of the license class for which you are applying.
The school bus endorsement is required when transporting pre-primary, primary or secondary school students from home to school, from school to home, or to and from school sponsored events.
CDL school bus drivers cannot legally operate a yellow school bus if they do not have the (S) School Bus Endorsement.
- None of these answers are correct
- The loss rate should be less than 3 psi in 2 minutes for single vehicles and less than 4 psi in 2 minutes for combination vehicles
- The loss rate should be less than 3 psi in 1 minute for single vehicles and less than 4 psi in 1 minute for combination vehicles
- The loss rate should be less than 1 psi in 1 minute for single vehicles and less than 2 psi in 1 minute for combination vehicles
Quote From Page 66 Of The CDL Manual:
Test air leakage rate: With a fully-charged air system (typically 125 psi), turn off the engine, release the service brake, and time the air pressure drop. The loss rate should be less than 2 psi in 1 minute for single vehicles and less than 3 psi in 1 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 3 psi in 1 minute for single vehicles and more than 4 psi for combination vehicles, the air loss rate is too much. Check for air leaks, and repair before driving the vehicle. Otherwise, you could lose your brakes while driving.
You really need to memorize the allowable air leakage rates. This will very likely come up on your written exam and will come up again during the pre-trip exam. Here's what you should memorize (create flash cards if you have to).
With the service brakes released (not depressing the brake pedal):
- Air loss rate should be less than 2 psi in 1 minute for a single vehicle.
- Air loss rate should be less than 3 psi in 1 minute for combination vehicles (vehicles with a trailer).
With the service brakes depressed (pressing the brake pedal):
- Air loss rate should be less than 3 psi in 1 minute for a single vehicle.
- Air loss rate should be less than 4 psi in 1 minute for combination vehicles (vehicles with a trailer).
Be sure to have that memorized. Very important!!
- Void Filler
- Edge Protector
- Working Load Limit
Quote From Page 1 Of The CDL Manual:
A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
Quote From Page 119 Of The CDL Manual:
Tires: The following items must be inspected on every tire:
- Tread depth - Check for minimum tread depth (4/32-inch on steering axle tires, 2/32-inch on all other tires).
- Tire condition - Check that tread is evenly worn and look for cuts or other damage to tread or sidewalls. Also, make sure that valve caps and stems are not missing, broken or damaged.
- Tire inflation - Check for proper inflation by using a tire gauge or by striking tires with a mallet or other similar device.
When checking a steer tire, say to the examiner:
"I'm checking the steer tire to make sure the tread is evenly worn and there are no abrasions, bulges, or cuts to tread or sidewalls. The tread must have a minimum depth of 4/32 of an inch. The tires must be properly inflated according to factory specifications. Tire inflation on steer tires must be checked with a tire gauge."
- Downshift to a lower gear to help slow the vehicle
- All of these are steps you should take if you lose brake pressure
- Use the parking brake to slow the vehicle down
- Pump the brakes to try and regenerate hydraulic pressure
Quote From Page 43 Of The CDL Manual:
Loss of hydraulic pressure: When the system will not build up pressure, the brake pedal will feel spongy or go to the floor. Following are things you can do:
- Downshift - Putting the vehicle into a lower gear will help to slow the vehicle.
- Pump the brakes - Sometimes pumping the brake pedal will generate enough hydraulic pressure to stop the vehicle.
- Use the parking brake - The parking or emergency brake is separate from the hydraulic brake system. Therefore, it can be used to slow the vehicle. However, be sure to press the release button or pull the release lever at the same time you use the emergency brake so you can adjust the brake pressure and keep the wheels from locking up.
If you are becoming a Class-A licensed truck or bus driver, there is a very low chance you'll drive a commercial vehicle with hydraulic brakes, but you may still be asked a question about hydraulic brakes on the written exam.
- Report en-route accidents to proper government agencies
- All of these are shipper responsibilities
- Placard the vehicle
- Package, mark and label the materials
Quote From Page 87 Of The CDL Manual:
- Sends products from one place to another by truck, rail, vessel or airplane.
- Uses the hazardous materials regulations to decide the product's:
- Proper shipping name
- Hazard class
- Identification number
- Correct packaging
- Correct label and markings
- Correct placards
- Must package, mark and label the materials, prepare shipping papers, provide emergency response information and supply placards.
- Must certify on the shipping paper that the shipment has been prepared according to the rules (unless you are pulling cargo tanks supplied by you or your employer)
Be sure to understand the different responsibilities for:
- The shipper
- The carrier
- The driver
- Straddle both lanes until you're up to speed in order to prevent vehicles from passing
- Move into the left-most lane
- Make sure the turn signal is off
- Accelerate as slowly as possible
Quote From Page 128 Of The CDL Manual:
After the turn:
- Make sure turn signal is off.
- Get up to speed of traffic, use turn signal, and move into right-most lane when safe to do so (if not already there).
Semi-trucks do not come with self-cancelling turn signals. You must cancel turn signals manually. Therefor, it is extremely important to remember to cancel your turn signal after making a turn. Driving with your turn signal on is not only very dangerous, it will cost you points during the driving exam.
- Be put in the manual lock position
- Be free of oil and grease
- Be tilted down towards the rear of the tractor
- Have the jaws closed
Quote From Page 75 Of The CDL Manual:
Inspect Fifth Wheel Check for damaged/missing parts.
- Check to see that mounting to tractor is secure, no cracks in frame, etc.
- Be sure that the fifth wheel plate is greased as required. Failure to keep the fifth wheel plate lubricated could cause steering problems because of friction between the tractor and trailer.
- Check if fifth wheel is in proper position for coupling:
- Wheel tilted down towards rear of tractor.
- Jaws open.
- Safety unlocking handle in the automatic lock position.
- If you have a sliding fifth wheel, make sure it is locked.
- Make sure the trailer kingpin is not bent or broken.
