Sample Kentucky CDL Test Questions - General Knowledge

Question 1

A parking sign displaying the International Symbol of Accessibility identifies:

This sign indicates ___________.
  1. A Parking reserved for persons with disabilities
  2. B An area where parking is prohibited
  3. C A space available to any vehicle
  4. D Short-term parking for deliveries

Correct answer: A – Parking reserved for persons with disabilities

The Accessible Parking sign uses the International Symbol of Accessibility to designate a parking space reserved for persons with disabilities. It does not indicate general, short-term, or prohibited parking. Any additional plaque, such as VAN ACCESSIBLE, provides more specific information about the space.

Question 2

In safe commercial driving, what is the main purpose of communicating with other road users?

  1. A Making telephone calls while driving
  2. B Applying the brakes repeatedly
  3. C Sounding the horn at every intersection
  4. D Showing what you intend to do

Correct answer: D – Showing what you intend to do

Communicating means giving other road users information about your intentions. The Kentucky CDL manual emphasizes using signals before turns and lane changes and warning following drivers when slowing or stopping. Clear, timely signals allow others more time to respond safely.

Question 3

What does a SLOWER TRAFFIC KEEP RIGHT sign direct a driver to do?

This sign indicates that drivers ___________.
  1. A Use the right lane when traveling slower than the normal traffic flow
  2. B Remain in the right lane for the entire trip
  3. C Pass slower vehicles only on their right
  4. D Increase speed until matching the fastest traffic

Correct answer: A – Use the right lane when traveling slower than the normal traffic flow

The sign directs slower traffic toward the right lane on a multilane through roadway. It is used where slower vehicles in the left lanes may impede the normal flow of traffic or cause unnecessary lane changes. It does not direct drivers to exceed a safe or lawful speed.

Source: Manual on Uniform Traffic Control Devices, 11th ed. — § 2B.38, “KEEP RIGHT EXCEPT TO PASS Sign (R4-16), SLOWER TRAFFIC KEEP RIGHT Sign (R4-3), and TRUCKS USE RIGHT LANE Sign (R4-5)”

Question 4

A driver may transport liquid or gas in a tank that is leaking.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

The Kentucky CDL manual expressly prohibits carrying liquids or gases in a leaking tank. Before loading, unloading, or driving, inspect under and around the tank and check its shell, valves, pipes, connections, hoses, covers, and vents for leaks. A leaking tank must not be used to transport cargo.

Question 5

What is the primary safety benefit of using a helper while backing a commercial vehicle?

  1. A The helper can monitor blind areas the driver cannot see
  2. B The helper can eliminate the need to use mirrors
  3. C The helper can hold the passenger-side mirror in place
  4. D The helper can operate the steering wheel for the driver

Correct answer: A – The helper can monitor blind areas the driver cannot see

A helper can watch blind areas that the driver cannot see while backing. The Kentucky CDL manual directs the helper to stand near the rear where the driver can see them. Before moving, the driver and helper should agree on clear hand signals, especially a signal to stop.

Question 6

Under normal parking conditions, which location requires at least 300 feet of separation from a vehicle carrying Division 1.1, 1.2, or 1.3 explosives?

  1. A A bridge or tunnel
  2. B A dwelling or place where people work or gather
  3. C An open fire
  4. D All of these locations

Correct answer: D – All of these locations

Federal regulations generally prohibit parking these explosive loads within 300 feet of a bridge, tunnel, dwelling, or place where people work or gather. A narrow exception applies when brief operational necessities make other parking impracticable. A vehicle carrying hazardous materials must not be parked within 300 feet of an open fire.
