Good Luck!

After making a turn, you should:
  • Straddle both lanes until you're up to speed in order to prevent vehicles from passing
  • Accelerate as slowly as possible
  • Make sure the turn signal is off
  • Move into the left-most lane
This is a question from page 88 - click here to look up the answer

Quote From Page 128 Of The Illinois 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).

TruckingTruth's Advice:

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.

While on a downgrade, how far below your "safe" speed should you go until you release the brakes?
  • 20mph
  • 15mph
  • 5mph
  • 10mph
This is a question from page 90 - click here to look up the answer

Quote From Page 130 Of The Illinois CDL Manual:

Select a safe speed, one that is not too fast for the weight of the vehicle, length and steepness of the grade, weather and road conditions. Once a safe speed has been reached, apply the brake hard enough to feel a definite slowdown.
- When speed has been reduced to 5 mph below the safe speed, release the brakes. (This application should last for about 3 seconds.)
Once speed has increased to the safe speed, repeat the procedure.

Example: If your “safe” speed is 40 mph, you should apply the brakes once your vehicle speed reaches 40 mph. Your brakes should be applied hard enough to reduce your speed to 35 mph. Once your vehicle speed reaches 35 mph, release the brakes. Repeat this procedure as often as necessary until you have reached the end of the downgrade. This braking technique is called "snubbing."

TruckingTruth's Advice:

Avoid riding the brakes during steep downgrades and choose your correct gear before descending the hill.

After driving under an overpass, the examiner may ask you:
  • The weight limit of the bridge
  • What street you drove under
  • What the posted clearance or height of the bridge was
  • The examiner will not ask any questions after driving under a bridge
This is a question from page 91 - click here to look up the answer

Quote From Page 131 Of The Illinois CDL Manual:

After driving under an overpass, you may be asked to tell the examiner what the posted clearance or height was. After going over a bridge, you may be asked to tell the examiner what the posted weight limit was. If your test route does not have a bridge or overpass, you may be asked about another traffic sign. When asked, be prepared to identify and explain to the examiner any traffic sign that may appear on the route.

TruckingTruth's Advice:

It is extremely important that you real all your signs during the driving exam. It is very likely that an examiner will ask about height clearance when driving under a bridge, and bridge weight ratings when driving over a bridge.

When stopping at an intersection, you should stop behind:
  • The crosswalk
  • The stop sign
  • The stop line
  • Whichever of these is first
This is a question from page 88 - click here to look up the answer

Quote From Page 128 Of The Illinois CDL Manual:

If you must stop before making the turn:

- Come to a smooth stop without skidding.
- Come to a complete stop behind the stop line, crosswalk or stop sign.
- If stopping behind another vehicle, stop where you can see the rear tires on the vehicle ahead of you (safe gap).
- Do not let your vehicle roll.
- Keep the front wheels aimed straight ahead.

TruckingTruth's Advice:

Make sure you stop before the stop line, crosswalk, or stop sign - whichever comes first. After you've made a complete stop, you can inch forward to get a better view of cross traffic if needed.

A vehicle displaying placards must stop at all railroad crossings except:
  • Crossings within industrial facilities
  • Crossings marked as exempt
  • Tracks used only for freight purposes (no passenger trains)
  • Crossings with no lights or gates
This is a question from page 91 - click here to look up the answer

Quote From Page 130 Of The Illinois CDL Manual:

If you are driving a bus, a school bus or a vehicle displaying placards, be prepared to observe the following procedures at every railroad crossing (unless the crossing is exempt):

- As the vehicle approaches a railroad crossing, activate the four-way flashers.
- Stop the vehicle within 50 feet but not less than 15 feet from the nearest rail and set parking brake.
- Listen and look in both directions along the track for an approaching train and for signals indicating the approach of a train. If operating a bus, you must open the window and door prior to crossing tracks.
- Keep hands on the steering wheel as the vehicle crosses the tracks.
- Do not stop, change gears or change lanes while any part of your vehicle is proceeding across the tracks.
- The 4-way flashers should be deactivated after the vehicle crosses the tracks.

TruckingTruth's Advice:

Tracks with signage that says "exempt" or "abandoned" are the only exceptions for placarded vehicles.

When pulling back onto the roadway from the shoulder, you should deactivate your four-way flashers:
  • Before rolling forward to re-enter the traffic flow
  • After you have re-entered the traffic lane
  • Once you are in the traffic lane and up to highway speeds
  • For approximately 30 seconds after re-entering traffic flow
This is a question from page 89 - click here to look up the answer

Quote From Page 129 Of The Illinois CDL Manual:

When instructed to resume:

- Check traffic and mirrors thoroughly in all directions.
- Turn off the four-way flashers.
- Activate the left turn signal.
- When traffic permits, release the parking brake and pull straight ahead.
- Do not turn the wheel before your vehicle moves.
- Check traffic from all directions, especially to the left.
- Steer and accelerate smoothly into the proper lane when safe to do so.
- Once your vehicle is back into the flow of traffic, cancel the left turn signal.

TruckingTruth's Advice:

Before you begin moving forward, you should activate the left turn signal so other motorists know you're getting ready to re-enter the traffic lane.

If stopping behind another vehicle, where should you stop?
  • Where you can see the rear license plate of the vehicle ahead of you
  • Where you can see the rear tires on the vehicle ahead of you
  • As close as possible so no vehicles will cut in front of you
  • At least 5 car lengths back

Quote From Page 128 Of The Illinois CDL Manual:

If stopping behind another vehicle, stop where you can see the rear tires on the vehicle ahead of you (safe gap).

TruckingTruth's Advice:

Examiners do check your "safe gap" when stopped behind other vehicles. Be certain you can see the rear tires of the vehicle in front of you.

  • Speed up to clear the crossing as quickly as possible
  • Slow down, look and listen for the presence of trains
  • None of these answers are correct
  • Downshift while crossing the railroad tracks
This is a question from page 91 - click here to look up the answer

Quote From Page 130 Of The Illinois CDL Manual:

Before reaching the crossing, all commercial drivers should:

- Decelerate, brake smoothly, and shift gears as necessary.
- Look and listen for the presence of trains.
- Check traffic in all directions.
- Do not stop, change gears, pass another vehicle or change lanes while any part of your vehicle is in the crossing.
