Sample Mississippi CDL Test Questions - General Knowledge

Question 1

About how far ahead do low-beam headlights normally illuminate the road?

  1. A 250 feet
  2. B 200 feet
  3. C 150 feet
  4. D 350 feet

Correct answer: A – 250 feet

Low-beam headlights normally let a driver see about 250 feet ahead. At night, adjust your speed so the vehicle’s stopping distance remains within the illuminated area. If you cannot stop within the distance you can see, you may not have enough time to respond after noticing a hazard.

Question 2

A parking sign marked RESERVED PARKING and displaying the blue wheelchair symbol identifies:

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

Correct answer: A – Parking reserved for persons with disabilities

The RESERVED PARKING sign containing the International Symbol of Accessibility identifies parking reserved for persons with disabilities. It is an accessible-parking sign, not a general parking or no-parking sign. Any additional plaque, such as VAN ACCESSIBLE, provides further information about the designated space.

Question 3

Which condition is a suspension-system defect?

  1. A A leaking shock absorber
  2. B An underinflated tire
  3. C A loose wheel lug nut
  4. D A cracked brake cylinder

Correct answer: A – A leaking shock absorber

The Mississippi CDL manual lists leaking shock absorbers among the defects to check in a suspension system. Shock absorbers should be secure, undamaged, and free of leaks. The other choices concern the tires, wheel hardware, or braking system rather than the suspension itself.

Question 4

A right-curve warning sign has a 40 MPH advisory plaque beneath it. What does the plaque indicate?

This sign warns drivers to _______________.
  1. A Vehicles traveling below 40 mph must use the right lane
  2. B Traffic must maintain a minimum speed of 40 mph
  3. C The advisory speed for the curve is 40 mph
  4. D Drivers should exceed 40 mph through the curve

Correct answer: C – The advisory speed for the curve is 40 mph

The 40 MPH plaque gives the advisory speed for the curve identified by the warning sign. Advisory speed plaques supplement advance warning signs and are based on an engineering study. Drivers of commercial vehicles may need to travel even more slowly when vehicle weight, a high center of gravity, weather, or road conditions require it.

Question 5

Which activities can distract a commercial driver?

  1. A Talking with passengers
  2. B Adjusting the radio or climate controls
  3. C Eating, drinking, or smoking
  4. D All of the above

Correct answer: D – All of the above

Talking with passengers, adjusting vehicle controls, and eating, drinking, or smoking are all listed as possible driver distractions. These activities can divert visual, mental, or physical attention from driving. A commercial driver should minimize distractions and keep full attention on traffic, the roadway, and vehicle control.

Question 6

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

  1. A Making telephone calls from the cab
  2. B Applying the brakes frequently
  3. C Sounding the horn continuously
  4. D Signaling your intentions

Correct answer: D – Signaling your intentions

Communicating includes signaling what you intend to do. Other road users cannot know that you plan to turn, change lanes, slow down, or stop unless you provide an appropriate signal. Clear and timely signals give others an opportunity to recognize and respond to your planned movement.
