Sample Kentucky CDL Test Questions - General Knowledge

Question 1

A yellow diamond sign shows the roadway bending left, with an advisory-speed plaque below it. What does the sign indicate?

This sign warns drivers to ____________.
  1. A A curve to the right at the posted advisory speed
  2. B A curve to the left at the posted advisory speed
  3. C A required left turn at the regulatory speed limit
  4. D A sharp right turn followed by a stop

Correct answer: B – A curve to the left at the posted advisory speed

The curve symbol indicates that the roadway bends to the left. The plaque below it displays the advisory speed for that roadway alignment, rather than establishing a regulatory speed limit. Kentucky has adopted the MUTCD as its standard for traffic-control devices.

Question 2

A tire becomes hot during travel and its pressure rises. Should you release air to return the pressure to its cold reading?

  1. A Yes
  2. B No

Correct answer: B – No

Air pressure normally increases as a tire becomes hot. Releasing air from a hot tire can leave it underinflated after it cools. If a tire is too hot to touch, remain stopped until it cools because continued operation could result in a blowout or fire.

Question 3

Which feature identifies a commercial vehicle equipped with an antilock braking system?

  1. A A speed-retarder control
  2. B A warning that appears only during hard braking
  3. C A yellow ABS malfunction lamp
  4. D An automatic transmission

Correct answer: C – A yellow ABS malfunction lamp

ABS-equipped trucks, tractors, and buses have a yellow ABS malfunction lamp on the instrument panel. An equipped trailer has a yellow lamp on its left side. The lamp normally illuminates briefly during a system check; a lamp that remains on or comes on while driving indicates that ABS may not be working properly.

Question 4

When backing a commercial vehicle toward a loading dock, which practice is unsafe?

  1. A Positioning the vehicle for driver-side backing when possible
  2. B Using a helper and agreed-upon hand signals
  3. C Continuing backward until contact with the dock stops the vehicle

Correct answer: C – Continuing backward until contact with the dock stops the vehicle

Back slowly enough to correct steering errors and stop quickly when necessary. Driver-side backing improves visibility, and a helper can monitor blind areas if the driver and helper agree on signals beforehand. The vehicle must remain under the driver’s control rather than relying on contact with the dock to end the maneuver.

Question 5

What must a driver do when approaching an octagonal red STOP sign?

When approaching this sign, you are required to _____________.
  1. A Slow down only if other traffic is present
  2. B Proceed cautiously without stopping
  3. C Come to a complete stop at the proper stopping location
  4. D Stop only when pedestrians are crossing

Correct answer: C – Come to a complete stop at the proper stopping location

Kentucky law requires a complete stop at the marked stop line. If there is no stop line, stop before entering the near crosswalk; if neither exists, stop at the nearest point where approaching traffic can be seen before entering the intersecting roadway. After stopping, yield to traffic presenting an immediate hazard.

Question 6

Which action should a driver perform while monitoring a commercial vehicle during a trip?

  1. A Concentrate only on pedestrians near the roadway
  2. B Open the hood to check fluid levels while traffic is moving
  3. C Watch the gauges for indications of trouble
  4. D Ignore instruments until the next scheduled fuel stop

Correct answer: C – Watch the gauges for indications of trouble

The Kentucky CDL manual directs drivers to watch their gauges during a trip and use sight, hearing, smell, and feel to detect trouble. Critical items such as tires, wheels, brakes, lights, trailer connections, coupling devices, and cargo securement should be examined when the vehicle is stopped.
