Sample Texas CDL Test Questions - General Knowledge

Question 1

Which practice is recommended when driving at night?

  1. A Use high beams continuously, regardless of other traffic
  2. B Look directly into approaching headlights
  3. C Drive slowly enough to stop within the distance you can see
  4. D Keep the instrument-panel lights at maximum brightness

Correct answer: C – Drive slowly enough to stop within the distance you can see

At night, drive slowly enough to stop within the distance you can see ahead. Headlights illuminate less roadway than daylight provides, and glare can make hazards harder to detect. Avoid staring into approaching headlights, dim your lights when required, and reduce speed when lighting is poor or confusing.

Question 2

Under ideal conditions, what is the minimum total stopping distance at 55 mph described in the handbook?

  1. A 277 feet
  2. B 350 feet
  3. C 419 feet
  4. D 500 feet

Correct answer: C – 419 feet

At 55 mph under ideal conditions, the handbook gives a minimum total stopping distance of 419 feet. This includes approximately 142 feet of perception distance, 61 feet of reaction distance, and 216 feet of braking distance. Actual stopping distance can increase because of poor traction, speed, vehicle condition, or other adverse factors.

Question 3

Under the general restrictions for a for-hire bus carrying passengers, which listed hazardous-material load is prohibited or exceeds permitted limits?

  1. A Any extremely dangerous Division 6.1 or Division 2.3 material, or any paranitroaniline
  2. B Class 1 explosives in the passenger space, except small-arms ammunition
  3. C More than 99 pounds of one non-Class 1 class or 496 pounds aggregate, unless a specific exception applies
  4. D All of the above

Correct answer: D – All of the above

Federal hazardous-material rules prohibit Class 1 explosives in passenger space except small-arms ammunition. They also prohibit extremely dangerous Division 6.1 or Division 2.3 materials and paranitroaniline on a passenger bus. Subject to specified exceptions, non-Class 1 hazardous materials are generally limited to 99 pounds per class and 496 pounds in aggregate.

Question 4

In a Texas temporary traffic-control zone, what does the Workers symbol sign warn about?

This sign warns drivers that _____________.
  1. A A sign intended only for the work crew
  2. B Workers in or near the roadway
  3. C A roadway that is completely closed
  4. D A mandatory detour route

Correct answer: B – Workers in or near the roadway

The Workers symbol sign alerts road users that workers may be in or near the roadway. Drivers should be prepared to respond safely to the temporary traffic-control conditions ahead. Road closures, detours, and operating machinery are communicated by other signs designed for those specific conditions.

Question 5

On a tractor-trailer air-brake system, what does the emergency air line do?

  1. A Supplies air to the trailer air tanks
  2. B Controls application of the trailer emergency brakes
  3. C Performs both functions
  4. D Carries only the normal foot-brake signal

Correct answer: C – Performs both functions

The emergency, or supply, line fills the trailer air tanks and controls the trailer emergency brakes. A loss of pressure in this line causes the trailer emergency brakes to apply. The Texas handbook also explains that the pressure loss may result from a trailer separation or a broken air line or component.

Question 6

Which component is part of a commercial vehicle's steering linkage?

  1. A Torque rod
  2. B Pitman arm
  3. C Leaf spring
  4. D Shock absorber

Correct answer: B – Pitman arm

The pitman arm is a steering-system component. It connects the steering gear's movement to other parts of the steering linkage. Torque rods, leaf springs, and shock absorbers are associated with the suspension rather than the steering linkage.
