Sample Mississippi CDL Test Questions - General Knowledge

Question 1

What handling problem can result from placing excessive weight on the steering axle?

  1. A Hard steering
  2. B Unusually light steering
  3. C Easier braking
  4. D Reduced brake-pedal effort

Correct answer: A – Hard steering

Too much weight on the steering axle can make steering difficult. It also may damage the steering axle and tires. Cargo must be distributed so that the steering and drive axles carry enough weight for safe control without exceeding their appropriate limits.

Question 2

Before using a helper while backing, which hand signal is most important to agree upon?

  1. A Stop
  2. B Continue straight back
  3. C Turn toward the driver’s side
  4. D Turn toward the passenger’s side

Correct answer: A – Stop

Before backing, the driver and helper should establish hand signals that both understand, especially a clear signal for “stop.” The helper should remain near the rear of the vehicle in a position where the driver can see the helper. Back slowly and stop if the helper disappears from view or gives the agreed signal.

Question 3

A Mississippi CDL holder is convicted of speeding while driving a personal vehicle. When must the driver notify the current employer?

  1. A Within 74 hours
  2. B Within 3 days
  3. C Within 30 days
  4. D Only when the conviction involved a commercial vehicle

Correct answer: C – Within 30 days

Federal regulation requires notification to the current employer within 30 days after a conviction for a state or local motor-vehicle traffic-control violation, other than a parking violation. The rule applies regardless of whether the violation occurred in a commercial or personal vehicle. The notification must be made in writing and include the required identifying and conviction information.

Question 4

Under normal parking conditions, a vehicle carrying Division 1.1, 1.2, or 1.3 explosives must not park within 300 feet of:

  1. A A bridge, tunnel, or dwelling
  2. B A place where people work, congregate, or assemble
  3. C An open fire
  4. D All of the above

Correct answer: D – All of the above

A vehicle carrying Division 1.1, 1.2, or 1.3 explosives generally may not park within 300 feet of a bridge, tunnel, dwelling, or place where people work or assemble. Federal rules provide a limited exception for brief stops required by operating necessities when no other location is practical. A hazardous-materials vehicle may not park within 300 feet of an open fire.

Question 5

Unless the manufacturer specifies a different procedure, how is hydraulic brake-pedal pressure checked?

  1. A While moving, pump 3 times and hold for 5 seconds
  2. B While moving, pump 5 times and hold for 3 seconds
  3. C With the vehicle in park, pump 3 times and hold for 5 seconds
  4. D With the vehicle in park, pump 5 times and hold for 3 seconds

Correct answer: C – With the vehicle in park, pump 3 times and hold for 5 seconds

Place the transmission in park, identify the normal pedal height, pump the brake pedal three times, and hold it down for five seconds unless the manufacturer specifies otherwise. After the initial application, the pedal should remain firm and should not continue moving downward. Hydraulic systems vary, so the driver must know the manufacturer’s procedure for the vehicle being tested.

Question 6

An empty truck generally has better braking performance than the same truck when loaded.

  1. A True
  2. B False

Correct answer: B – False

Empty trucks may require more stopping distance because they have less traction. With less weight pressing the tires against the road, the wheels can lock and skid more readily during hard braking. An empty truck should not be treated as though it will always stop more quickly than a loaded one.
