When at the scene of an accident with injuries, when should you assist the injured?
  • Assist the injured immediately
  • You should never assist the injured until authorities have arrived
  • Assist the injured only after you have protected the area and notified authorities
  • Assist the injured after you have protected the area, but before you have notified authorities
This is a question from page 30 - click here to look up the answer

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.

TruckingTruth's Advice:

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 the following are reasons to back towards the drivers side of your vehicle except:
  • Less accidents occur while backing towards the drivers side instead of the passenger side
  • By backing towards the drivers side, you should be able to keep your window closed during inclement weather
  • Backing towards the drivers side offers better visibility than backing towards the right side
  • If you back and turn toward the driver's side, you can watch the rear of your vehicle by looking out the side window
This is a question from page 15 - click here to look up the answer

Quote From Page 24 Of The Illinois CDL Manual:

Back to the driver's side so you can see better. Backing toward the right side is very dangerous because you cannot see as well. If you back and turn toward the driver's side, you can watch the rear of your vehicle by looking out the side window. Use driver-side backing-even if it means going around the block to put your vehicle in this position. The added safety is worth it.

TruckingTruth's Advice:

Backing towards the passenger side is often referred to as "blind side backing." It is very dangerous due to low visibility and should be avoided whenever possible, especially in a combination vehicle.

If you are being tailgated, you should do the following to reduce the chances of an accident:
  • Flash your brake lights to communicate you want the vehicle behind you to open their following distance
  • Speed up to increase the distance between yourself and the vehicle behind you
  • Make a quick lane change
  • None of these answers are correct
This is a question from page 21 - click here to look up the answer

Quote From Page 32 Of The Illinois CDL Manual:

If you are being tailgated, do the following to reduce the chances of an accident: Avoid quick changes. If you have to slow down or turn, signal early and reduce speed very gradually. Increase your following distance. Opening up room in front of you will help you avoid having to make sudden speed or direction changes. It also makes it easier for the tailgater to get around you. Do not speed up. It is safer to be tailgated at a low speed than a high speed. Avoid tricks. Do not turn on your taillights or flash your brake lights. Follow the suggestions above.

During a pre-trip inspection, all belts should be checked. Which item in the engine compartment may be belt driven?
  • Steering pump
  • Water pump
  • Turbo
  • All of these may be belt driven
This is a question from page 9 - click here to look up the answer

Quote From Page 16 Of The Illinois CDL Manual:

Check belts for tightness and excessive wear (alternator, water pump, air compressor)-learn how much "give" the belts should have when adjusted right, and check each one.

TruckingTruth's Advice:

When checking any belts, be sure they aren't frayed, cracked, or broken.

If you are in a 60-foot vehicle traveling 55mph, what should your following distance be?
  • 9 seconds
  • 8 seconds
  • 6 seconds
  • 7 seconds
This is a question from page 21 - click here to look up the answer

Quote From Page 31 Of The Illinois CDL Manual:

One good rule for how much space you should keep in front of you is at least 1 second for each 10 feet of vehicle length at speeds below 40 mph. At greater speeds, you must add 1 second for safety. For example, if you are driving a 40-foot vehicle, you should leave 4 seconds between you and the vehicle ahead. In a 60-foot rig, you will need 6 seconds. Over 40 mph, you would need 5 seconds for a 40-foot vehicle and 7 seconds for a 60-foot vehicle.

TruckingTruth's Advice:

These types of questions are very common during the written exam and can be a bit confusing as they change the size of the vehicle as well as their speeds. But it's rather simple to calculate: For each 10 feet of vehicle, you need 1 second of following distance. Anything over 40mph, simply add 1 second to your total. Be 100% confident about this formula before taking the written exam as this will probably show up.

This is a question from page 32 - click here to look up the answer

Quote From Page 48 Of The Illinois CDL Manual:

- 12-oz. glass of 5% beer
