Sample Alabama CDL Test Questions - General Knowledge

Question 1

A yellow warning sign shows a sharp right turn followed by a sharp left turn. What does it indicate?

This sign warns drivers to _____________.
  1. A A gradual right curve followed by a gradual left curve
  2. B One sharp right turn
  3. C One sharp left turn
  4. D Two sharp turns ahead, first right and then left

Correct answer: D – Two sharp turns ahead, first right and then left

This is a Reverse Turn warning sign. It indicates two changes in roadway alignment in opposite directions, with the first turn matching the direction shown at the bottom of the symbol. It differs from a Reverse Curve sign, which represents more gradual changes in alignment.

Question 2

A yellow diamond sign contains a black symbol shaped like the letter Y. What is ahead?

This sign warns drivers to _____________.
  1. A A T-intersection
  2. B A Y-intersection
  3. C A road construction zone
  4. D A dip at an intersection

Correct answer: B – A Y-intersection

The Y-Intersection warning sign indicates that the roadway ahead forms a Y-shaped intersection. It alerts drivers to the presence of the intersection and the possibility of turning or entering traffic. The sign depicts the general roadway configuration rather than assigning right-of-way.

Question 3

Into how many numbered hazard classes are hazardous materials organized?

  1. A 3
  2. B 6
  3. C 9
  4. D 12

Correct answer: C – 9

Federal hazardous-materials regulations organize regulated materials into nine numbered hazard classes. The classes cover hazards such as explosives, gases, flammable liquids, corrosives, radioactive materials, and miscellaneous dangerous goods. Several classes are further divided into divisions that describe more specific hazards.

Question 4

An 8-foot cargo article is not blocked or positioned to prevent forward movement. What is the minimum number of tiedowns required?

  1. A 1
  2. B 2
  3. C 3
  4. D 4

Correct answer: B – 2

Federal cargo-securement rules require at least two tiedowns for an unblocked article that is longer than 5 feet but no longer than 10 feet, regardless of its weight. Different minimums apply to shorter, lighter articles and cargo that has been blocked or braced. The securement system must also prevent cargo movement.

Question 5

Under which conditions should a driver turn off a vehicle's retarder?

  1. A When the roadway is wet, icy, or snow-covered
  2. B Whenever traveling through mountainous terrain
  3. C Only when the pavement is clear and dry
  4. D A retarder cannot be switched off

Correct answer: A – When the roadway is wet, icy, or snow-covered

A retarder applies braking force to the drive wheels. On wet, icy, or snow-covered roads, poor traction can allow those wheels to skid when the retarder operates. Turn the retarder off under these conditions unless the vehicle manufacturer provides different instructions for the specific system.

Question 6

A round yellow sign marked with a black X and the letters RR warns of:

These signs alert the driver _____________.
  1. A A school zone ahead
  2. B Debris or another roadway obstruction
  3. C A four-way stop ahead
  4. D A railroad crossing ahead

Correct answer: D – A railroad crossing ahead

This round sign is the advance warning for a railroad-highway crossing. The Alabama CDL manual instructs drivers who see it to slow down, look and listen for a train, and be prepared to stop. The sign is placed before the tracks and is different from the crossbuck located at the crossing.
