Sample Maine CDL Test Questions - General Knowledge

Question 1

When backing, why should you turn toward the driver’s side whenever possible?

  1. A Traffic law requires all backing turns to be made that way
  2. B The maneuver can be completed faster
  3. C You have a better view of the vehicle’s path and rear
  4. D You do not need to use the passenger-side mirror

Correct answer: C – You have a better view of the vehicle’s path and rear

The Maine Commercial Driver License Manual recommends driver-side backing because it provides better visibility. When turning toward that side, you can monitor the vehicle’s rear through the side window while continuing to check both mirrors. Back slowly, inspect the path beforehand, and use a helper whenever possible.

Question 2

A yellow diamond sign showing a walking person warns that:

This sign warns drivers  _____________.
  1. A Pedestrians may enter or cross the roadway
  2. B Only bicycle traffic may cross ahead
  3. C Every vehicle must make a complete stop
  4. D Pedestrians are prohibited from the area

Correct answer: A – Pedestrians may enter or cross the roadway

The walking-person symbol is a pedestrian warning sign. It alerts drivers to a location where pedestrians may enter, cross, or share the roadway unexpectedly. Watch the road and nearby areas carefully, control your speed, and be prepared to respond if someone enters your path.

Question 3

Before departure, you find that a hazardous-material package is visibly leaking. What must you do?

  1. A Accept it if the trip will be short
  2. B Load it carefully and avoid rough roads
  3. C Carry it only on local streets
  4. D Refuse it and do not transport it in that condition

Correct answer: D – Refuse it and do not transport it in that condition

Maine’s CDL manual directs drivers to refuse leaking hazardous-material packages. Federal hazardous materials regulations require packages to prevent an identifiable release under conditions normally encountered in transportation and prohibit transporting a shipment that is not properly prepared. The package must be corrected or properly repackaged before it may be accepted for transport.

Question 4

Which is one basic reason for covering cargo carried on an open bed?

  1. A To prevent theft during every stop
  2. B To satisfy the vehicle manufacturer’s warranty
  3. C To protect the cargo from weather
  4. D To increase the vehicle’s legal weight limit

Correct answer: C – To protect the cargo from weather

A cargo cover can protect a load from weather while it is being transported. The CDL manual also identifies protecting people from spilled cargo as a basic reason for using a cover. Any tarp or other covering must be secured properly so it does not tear, billow, block mirrors, or obscure required lights.

Question 5

What does a red WRONG WAY sign tell a driver?

This sign warns drivers that  _________________.
  1. A An expressway entrance is ahead
  2. B Traffic volume will increase ahead
  3. C The vehicle is traveling against the permitted direction of traffic
  4. D The road ahead is open but requires extra caution

Correct answer: C – The vehicle is traveling against the permitted direction of traffic

A WRONG WAY sign warns that you are proceeding opposite the lawful direction of traffic. It is commonly used with DO NOT ENTER signs where wrong-way entry onto a one-way roadway is possible. Do not continue into or along the roadway against approaching traffic; correct the situation as safely as conditions permit.

Question 6

How does a bridge formula generally affect allowable weight when axles are placed closer together?

  1. A It permits more weight on the axle group
  2. B It permits less weight on the axle group
  3. C It allows the same weight at every axle spacing
  4. D It changes only the manufacturer’s GVWR

Correct answer: B – It permits less weight on the axle group

The federal bridge formula considers the number of axles and the distance between the outer axles in a group. Shorter spacing generally results in a lower allowable weight for that axle group. Maine’s CDL manual summarizes this principle as allowing less maximum axle weight when axles are closer together, helping prevent bridge and roadway overloading.
