Quote From Page 129 Of The Illinois CDL Manual:

You will be instructed to change lanes:

- Make necessary traffic checks.
- Use proper signals.

Quote From Page 130 Of The Illinois CDL Manual:

As you approach an upgrade:

- Select the proper gear to maintain speed and not lug the engine.
- Check traffic thoroughly in all directions and move to the right-most or curb lane.
- If legal to do so, use the 4-way flashers if traveling too slowly for the flow of traffic.

TruckingTruth's Advice:

Check your local and state laws regarding the use of 4-way flashers while driving slowly. Some states require it, while other states prohibit the practice.

During a turn, when should you change gears?
  • Only in the first half of the turn
  • About half way through the turn
  • About 3/4 of the way through the turn
  • Only after the turn has been completed
This is a question from page 88 - click here to look up the answer

Quote From Page 128 Of The Illinois CDL Manual:

When ready to turn:

- Check traffic in all directions.
- Keep both hands on the steering wheel during the turn.
- Do not change gears during the turn.
- Keep checking your mirror to make sure the vehicle does not hit anything on the inside of the turn.
- Vehicle should not move into oncoming traffic.
- Vehicle should finish turn in correct lane.

TruckingTruth's Advice:

While taking your driving exam, remember to never shift gears during a turn. Once your tractor has completed the turn, you may shift up. You do not have to wait for the trailer to completely straighten out.

When approaching a curve, you should:
  • Continue slowing down during the curve, and downshift about half way through the curve
  • Slow down before entering the curve as to avoid braking or shifting during the curve
  • Continue to slow down throughout the entire duration of the curve
  • Depress the clutch pedal and coast through the turn
This is a question from page 89 - click here to look up the answer

Quote From Page 130 Of The Illinois CDL Manual:

When approaching a curve:

- Check traffic thoroughly in all directions.
- Before entering the curve, reduce speed so further braking or shifting is not required in the curve.
- Keep vehicle in the lane.
- Continue checking traffic in all directions.

TruckingTruth's Advice:

Always slow down and get into the correct gear before the curve and never shift during the curve. It's better to slow down too much than not enough.

Which of the following is NOT allowed during your driving exam:
  • "Floating" the gears (shifting without using the clutch pedal)
  • Shifting in turns
  • None of these are allowed during the driving exam
  • Resting your foot on the clutch pedal (riding the clutch)
This is a question from page 91 - click here to look up the answer

Quote From Page 131 Of The Illinois CDL Manual:

Clutch usage (for manual transmission):

- Always use the clutch to shift.
- Double-clutch if vehicle is equipped with non-synchronized transmission.
- Do not rev or lug the engine.
- Do not ride the clutch to control speed, coast with the clutch depressed, or "pop the clutch."

Gear usage (for manual transmission):

- Do not grind or clash gears.
- Select a gear that does not rev or lug engine.
- Do not shift in turns and intersections.

TruckingTruth's Advice:

You are not expected to shift perfectly. You only need to prove you are safe and will not pose a hazard to the general public. However, there are some basic rules you must follow.

- Do not stall the truck! This may result in an immediate failure.
- You must shift the transmission using the clutch (they will check for this).

Grinding or clashing gears will NOT result in an automatic failure. But it's important for you to learn how to recover when missing a gear. If you lose too much speed or stall the truck, you may be forced to retest.

While on a downgrade, how far below your "safe" speed should you go until you release the brakes?
  • 5mph
  • 10mph
  • 20mph
  • 15mph
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.

When making a right turn, you should:
  • Finish the turn in the left lane
  • Finish the turn in the center lane
  • Finish the turn in the right most (curb) lane
  • If two lanes are available, straddle both lanes until the trailer is straight, then choose a safe lane
This is a question from page 91 - click here to look up the answer

Quote From Page 131 Of The Illinois CDL Manual:

Lane usage:

- Do not put vehicle over curbs, sidewalks or lane markings.
- Stop behind stop lines, crosswalks or stop signs.
- Complete a turn in the proper lane on a multiple-lane road (vehicle should finish a left turn in the lane directly to the right of the center line).
- Finish a right turn in the right-most (curb) lane.
- Move to or remain in right-most lane unless lane is blocked.

TruckingTruth's Advice:

When making a left turn, finish the turn in the left lane and when making a right turn, finish the turn in the right lane. Be sure no vehicles "squeeze" next to you while making the turn.

A vehicle displaying placards must stop at all railroad crossings except:
  • Crossings marked as exempt
  • Crossings with no lights or gates
  • Tracks used only for freight purposes (no passenger trains)
  • Crossings within industrial facilities
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.
