Sample CDL Doubles & Triples practice questions
Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.
- Question 1Weight Limits
When driving a commercial vehicle combination consisting of a tractor and two trailers (a double), what is the maximum gross vehicle weight rating (GVWR) allowed by Connecticut law for a vehicle operating with a Class A CDL, assuming all equipment is properly rated and placarded?
- A.120,000 pounds
- B.80,000 pounds(Correct)
- C.There is no specific GVWR limit for doubles, only that each component must be rated for its load.
- D.100,000 pounds
Explanation
The maximum gross vehicle weight rating (GVWR) for any commercial motor vehicle, including doubles and triples, is generally 80,000 pounds, as per federal regulations adopted by Connecticut. Exceeding this limit requires special permits.
- Question 2Pre-Trip Inspection
You are performing a pre-trip inspection on a tractor-trailer with a single 28-foot trailer. You notice a significant amount of slack in the steering wheel, approximately 3 inches of total play at the rim. According to CDL standards, what is the maximum allowable free play for a steering wheel on a heavy commercial vehicle?
- A.6 inches
- B.3 inches
- C.2 inches(Correct)
- D.1 inch
Explanation
For most heavy commercial vehicles, the maximum allowable steering wheel play is 2 inches at the rim when the wheels are pointed straight ahead. More than 2 inches of play can indicate worn steering components and is considered a safety defect.
- Question 3Air Brakes
While inspecting the air brake system of a tractor-trailer, you observe that the service brake application causes the tractor to pull sharply to the left. What is the most likely cause of this issue?
- A.A malfunctioning anti-lock braking system (ABS).
- B.Low air pressure in the service brakes.
- C.Worn brake pads on the left side of the tractor.
- D.A stuck or seized brake on the right side of the tractor.(Correct)
Explanation
A vehicle pulling sharply to one side during braking typically indicates that the brakes on one side are not applying as much force as the brakes on the other. A stuck or seized brake on the right side would cause the vehicle to pull left.
