- Using emergency flashers
- Honking a horn
- Flashing lights
- Using turn signals
Quote From Page 27 Of The Illinois CDL Manual:
Use your horn only when needed - Your horn can let others know you are there and help to avoid a crash. Use your horn when needed; however, it can startle others and could be dangerous when used unnecessarily.
- Assist the injured after you have protected the area, but before you have notified authorities
- Assist the injured only after you have protected the area and notified authorities
- Assist the injured immediately
- You should never assist the injured until authorities have arrived
Quote From Page 45 Of The Illinois CDL Manual:
If a qualified person is at the accident and helping the injured, stay out of the way unless asked to assist. Otherwise, do the best you can to help any injured parties:
- Do not move a severely injured person unless the danger of fire or passing traffic makes it necessary.
- Stop heavy bleeding by applying direct pressure to the wound.
- Keep the injured person warm.
If you are the first one on the scene of a serious accident, you may want to help the injured right away. But make sure you secure the scene of the accident first to avoid any additional collisions. You should then notify the authorities before attempting to assist an injured person. Make sure you memorize the order of recommended accident procedures:
1. Protect the area
2. Notify authorities
3. Assist the injured
- All of these answers are correct
- Pose a risk to health, safety, and property during transportation
- Require special load securement and containment
- Require a special license endorsement when transported in large quantities
Quote From Page 49 Of The Illinois CDL Manual:
All drivers should know something about hazardous materials. You must be able to recognize hazardous cargo and whether or not you can haul it without having a Hazardous Materials Endorsement added to your CDL license.
Hazardous materials are products that pose a risk to health, safety and property during transportation.

Quote From Page 27 Of The Illinois CDL Manual:
If you must stop on a road or the shoulder of any road, you must put out your emergency warning devices within 10 minutes.
Pay special attention to this and memorize it. There is a good chance this question will show up on your written exam.
- Downshift about half way down the hill
- Downshift once the RPM's become too high for the current gear
- None of these are correct
- Downshift before starting down the hill
Quote From Page 25 Of The Illinois 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.
- Applying and releasing the brakes to avoid locking the wheels
- Applying only the trailer brakes using the trailer brake valve to avoid a jackknife
- Applying the brakes as hard as possible without locking the wheels
- Applying the brakes as hard as possible and locking the wheels
Quote From Page 43 Of The Illinois CDL Manual:
Controlled braking: With this method, you apply the brakes as hard as you can without locking the wheels. Keep steering wheel movements very small while doing this. If you need to make a larger steering adjustment or if the wheels lock, release the brakes. Reapply the brakes as soon as you can.
A question about Controlled Braking and/or Stab Braking will likely show up on your written exam. Be sure to know the difference of each:
Controlled braking: With this method, you apply the brakes as hard as you can without locking the wheels.
Stab braking: Use only on vehicles without anti-lock brake systems.
- Apply your brakes all the way.
- Release brakes when wheels lock up.
- As soon as the wheels start rolling, apply the brakes fully again. (It can take up to 1 second for the wheels to start rolling after you release the brakes. If you reapply the brakes before the wheels start rolling, the vehicle will not straighten out.)
Note that most newer equipment (including trailers) have Anti-Lock Brake systems. That means controlled / stab braking is done automatically via the ABS system.
- On a tractor-trailer equipped with a trailer brake hand valve, the hand valve can be applied to keep from rolling back
- All of these are correct
- Partly engage the clutch before you take your right foot off the brake
- Engage the parking brake and only release it when you have applied enough engine power to keep from rolling back
Quote From Page 23 Of The Illinois CDL Manual:
Do not roll back when you start. You may hit someone behind you. Partly engage the clutch before you take your right foot off the brake. Put on the parking brake whenever necessary to keep from rolling back. Release the parking brake only when you have applied enough engine power to keep from rolling back. On a tractor-trailer equipped with a trailer brake hand valve, the hand valve can be applied to keep from rolling back.
- Get it repaired after your next delivery
- Let your dispatcher know
- Keep a daily log of the problem
- Get it repaired immediately
Quote From Page 22 Of The Illinois CDL Manual:
If you find anything unsafe during the pre-trip inspection, get it repaired immediately. Federal and state laws prohibit operating an unsafe vehicle.
