Sample Indiana CDL Test Questions - General Knowledge

Question 1

On a downgrade, brake fade has progressed until the vehicle no longer slows normally. What should you do?

  1. A Pump the pedal and remain on the roadway
  2. B Shift to a higher gear and continue downhill
  3. C Use an escape ramp or the least hazardous available escape route immediately
  4. D Continue to the bottom before stopping

Correct answer: C – Use an escape ramp or the least hazardous available escape route immediately

Brake fade can worsen until the vehicle cannot be slowed or stopped. If the brakes fail on a downgrade, use an available escape ramp. If there is no ramp, take the least hazardous escape route available, such as a road that levels out or turns uphill, as soon as the failure is recognized.

  2. B Slow down and yield without stopping
  3. C Stop only when cross traffic is approaching
  4. D Come to a complete stop every time

Correct answer: D – Come to a complete stop every time

  2. B False

Correct answer: B – False

School buses have blind spots and danger zones around them. The outside flat mirrors have blind areas immediately below and in front of each mirror and directly behind the rear bumper.

Federal rules require the driver to verify securement before operating and inspect the cargo and securement devices within the first 50 miles.

Limited exceptions apply when cargo inspection is prohibited or impracticable.

The NARROW BRIDGE sign warns that the usable roadway becomes narrower at the bridge. In Indiana, it is displayed as a diamond-shaped warning sign for a roadway condition ahead. Reduce speed as appropriate, watch your vehicle's clearance, and remain within the available lane space.
