Sample Kansas CDL Test Questions - General Knowledge

Question 1

Which statement about night driving and fatigue is correct?

  1. A High beams should be used continuously from 7 p.m. to 7 a.m.
  2. B Most drivers are more alert at night than during daylight hours
  3. C Many serious commercial-vehicle crashes occur between midnight and 6 a.m.
  4. D Road hazards are generally easier to identify at night

Correct answer: C – Many serious commercial-vehicle crashes occur between midnight and 6 a.m.

Driving through the night or during hours when you normally sleep raises the risk of drowsiness. The CDL manual notes that many serious crashes involving heavy motor vehicles occur between midnight and 6 a.m. Darkness also makes hazards harder to see, while fatigue can slow recognition and reaction.

Question 2

For a truck operated in Kansas, what is the minimum tread depth required on a front tire?

  1. A 2/32 inch
  2. B 4/32 inch
  3. C 6/32 inch
  4. D 1/4 inch

Correct answer: B – 4/32 inch

Federal equipment rules require at least 4/32 inch of tread in a major groove on each front tire of a bus, truck, or truck tractor. Measurements are not made at tie bars, humps, or fillets. Other tires generally require at least 2/32 inch of tread in a major groove.

Question 3

Which driver should be watched especially carefully as a possible traffic hazard?

  1. A A driver using a turn signal, because the signal confirms exactly where the vehicle will turn
  2. B A rental-truck driver who may be unfamiliar with the vehicle’s limited side and rear visibility

Correct answer: B – A rental-truck driver who may be unfamiliar with the vehicle’s limited side and rear visibility

Kansas CDL guidance identifies rental trucks as vehicles that deserve careful observation. Their drivers may not be accustomed to the restricted view along the sides and rear of a large truck. Recognizing such clues early gives a commercial driver more time to maintain space and respond safely if the other vehicle makes an unexpected movement.

Question 4

What does a SLIPPERY WHEN WET warning sign tell a commercial driver to do?

This sign warns drivers to _________________.
  1. A Reduce speed and use extra care to avoid skidding on a wet surface
  2. B Avoid using the road whenever rain is falling
  3. C Watch for a shoulder where vehicles may become stuck
  4. D Expect the road to be equally slippery in all weather

Correct answer: A – Reduce speed and use extra care to avoid skidding on a wet surface

The sign warns that unexpected slippery conditions may exist when the pavement is wet. A commercial driver should reduce speed and make smooth steering and braking inputs because wet roads increase stopping distance and make skidding more likely. The sign is a warning, not a prohibition against driving in rain.

Question 5

At a Kansas all-way stop, another driver stopped first and has begun entering the intersection. To whom must you yield?

  1. A The driver who stopped first and is entering the intersection
  2. B A driver on your left, regardless of arrival order
  3. C A driver on your right, regardless of whether that driver has stopped
  4. D No one once you have made a complete stop

Correct answer: A – The driver who stopped first and is entering the intersection

After stopping, a driver must yield to a vehicle already in the intersection or approaching closely enough to be an immediate hazard. Thus, the driver who stopped first and has begun entering should be allowed to proceed. If two vehicles enter from different roadways at approximately the same time, the driver on the left yields to the driver on the right.

Question 6

According to CDL safety guidance, what is the leading cause of injury and death in roadway work zones?

  1. A Speeding traffic
  2. B Wet pavement
  3. C Poorly adjusted brakes
  4. D Reduced nighttime visibility

Correct answer: A – Speeding traffic

The CDL manual identifies speeding traffic as the leading cause of injury and death in roadway work zones. Drivers should observe posted speed limits while approaching and passing through these areas. They must also remain alert for narrow lanes, workers, equipment, sudden stops, and changing traffic patterns.
