Sample Montana CDL Test Questions - General Knowledge

Question 1

Backing a school bus is a preferred maneuver whenever it saves time.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

Backing a school bus is strongly discouraged because it increases collision risk and should occur only when no safe alternative exists. Never back while students are outside the bus. Montana’s CDL manual directs a driver who must back to use a lookout, check mirrors and rear windows continuously, and move slowly and smoothly.

Question 2

Which practice does NOT follow safe guidance when backing toward a loading dock?

  1. A Approach from the driver’s side when practical
  2. B Use a visible helper and agreed hand signals
  3. C Increase backing speed after the vehicle is aligned

Correct answer: C – Increase backing speed after the vehicle is aligned

Always back as slowly as possible, including during the final approach to a dock. Driver-side backing improves visibility, and a helper can warn you about hazards in blind areas. Before beginning, make sure you and the helper understand the hand signals, especially the signal to stop.

Question 3

At a Montana four-way stop, another driver reaches a complete stop before you. Who normally proceeds first?

  1. A The driver who stopped before you
  2. B The driver on the left
  3. C The driver on the right, regardless of arrival order
  4. D Neither driver

Correct answer: A – The driver who stopped before you

After each vehicle makes the required complete stop, the driver who arrived first normally proceeds first. If two vehicles arrive at approximately the same time, the driver on the left must yield when the vehicle on the right is close enough to present an immediate hazard. Drivers should proceed only after confirming that the intersection is clear.

Question 4

During an air-brake inspection, a dual air system at operating rpm should normally build pressure between which levels within 45 seconds?

  1. A 85 to 100 psi
  2. B 40 to 60 psi
  3. C 60 to 80 psi
  4. D 100 to 120 psi

Correct answer: A – 85 to 100 psi

With the engine at operating rpm, pressure in a dual air system should normally rise from 85 to 100 psi within 45 seconds. Vehicles with air tanks larger than the required minimum may have a longer safe buildup time. In that situation, use the vehicle manufacturer’s specifications to evaluate the system.

Question 5

Which speed rule applies when operating a school bus in Montana?

  1. A The bus may never exceed 50 mph
  2. B The bus may never exceed 55 mph
  3. C The bus may never exceed 65 mph
  4. D Obey the posted limit and drive slower when conditions require it

Correct answer: D – Obey the posted limit and drive slower when conditions require it

School-bus drivers must follow all posted speed limits. They must also avoid driving faster than is reasonable and prudent for the weather, visibility, traffic, and roadway conditions, even when the posted limit is higher. Speed must never endanger students or property.

Question 6

Before transporting a sealed load, which condition must the driver verify?

  1. A Every item inside the sealed container is tied down
  2. B The shipper used a particular type of door lock
  3. C The contents are arranged by delivery order
  4. D Gross and axle weight limits are not exceeded

Correct answer: D – Gross and axle weight limits are not exceeded

A driver ordinarily cannot inspect the contents of a sealed load. The driver must still verify that the vehicle does not exceed applicable gross or axle weight limits. Containerized cargo must also be properly attached or secured to the vehicle, whether the container uses its own locking devices or is carried on a flatbed.
