Sample Connecticut CDL Test Questions - General Knowledge

Question 1

Under Connecticut’s definition, what is included in the gross weight of a tractor-trailer unit?

  1. A The tractor and driver only
  2. B The trailer and its load only
  3. C The tractor, trailer or semitrailer, and the load
  4. D Only the manufacturers’ weight ratings for the two units

Correct answer: C – The tractor, trailer or semitrailer, and the load

For a tractor-trailer, gross weight includes the light weight of the tractor, the light weight of the trailer or semitrailer, and the weight of the load. This is different from a gross combination weight rating, which is based on specified vehicle weight ratings. The question asks about actual gross weight.

Question 2

If reflective triangles are used as a commercial vehicle’s required warning devices, how many must be carried?

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

Correct answer: C – 3

Federal equipment rules specify a set of three bidirectional emergency reflective triangles as one permitted warning-device option for covered commercial power units. The Connecticut CDL manual likewise lists three red reflective triangles as required emergency equipment when triangles are used. Drivers should confirm that all three are present during the vehicle inspection.

Question 3

An orange diamond sign displaying the worker symbol warns that:

This sign warns drivers that _____________.
  1. A The sign applies only to road-crew vehicles
  2. B Workers may be in or near the roadway
  3. C The roadway is closed to all traffic
  4. D A marked detour must be followed

Correct answer: B – Workers may be in or near the roadway

The Workers sign alerts road users that workers may be in or near the roadway. It does not by itself indicate that the road is closed or that a detour is required. Drivers should recognize the possibility of people working close to moving traffic and respond to any additional work-zone controls.

Question 4

Which description best defines a driving hazard?

  1. A A road condition or road user that presents a possible danger
  2. B Only a solid object lying in the travel lane
  3. C Only something that completely blocks the roadway
  4. D Any situation involving financial risk

Correct answer: A – A road condition or road user that presents a possible danger

The Connecticut CDL manual defines a hazard as a road condition or road user—such as a driver, bicyclist, or pedestrian—that presents a possible danger. A hazard does not have to block the road or have already created an emergency. Identifying it early gives the driver more time to prepare and act.

Question 5

What is the minimum tread depth for a tire on the steering axle of a commercial vehicle?

  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 rules require at least 4/32 inch of tread-groove depth on the front wheels of covered buses, trucks, and truck tractors. The CDL manual describes this as 4/32 inch in every major groove on front or steering-axle tires. Most other tires require at least 2/32 inch.

Question 6

Wet commercial-vehicle brakes may cause which problems?

  1. A Wheel lockup
  2. B A trailer jackknife
  3. C Pulling to one side
  4. D All of these

Correct answer: D – All of these

The Connecticut CDL manual explains that brakes can become wet in heavy rain or deep standing water. Wet brakes may apply weakly or unevenly, or they may grab. The resulting problems can include reduced braking power, locked wheels, pulling to one side, and a jackknife when the vehicle is towing a trailer.
