To pass, the applicant must answer at least 16 questions correctly. Test questions come from the Wyoming Driver License Manual for Commercial and Heavy Vehicles. Questions come from chapters covering: Driving Safely, Tank Vehicles, Hazardous Materials and Combination Vehicles. The Tank endorsement can be used with the Class A, B or C CDL.

1. Passive railroad crossings:

Are controlled by flashing lights.

Are not controlled by any type of traffic control device.

Have gates that lower when trains are approaching.

Should never be crossed by a CMV.

Railroad crossings that are not controlled by any type of traffic control device are known as passive crossings. The decision to proceed across tracks at a passive crossing is entirely up to the driver.

2. The amount of liquid cargo than can be loaded into a tank depends on:

The time of year.

Legal weight limits.

The ability of the driver.

Factors that affect how much liquid is safe to load into your tank include how much the liquid will expand in transit, the weight of the liquid, and legal weight limits. If you are loading a particularly dense liquid, make sure you do not exceed legal weight limits.

3. When driving a vehicle with empty cargo tanks that are used to carry hazardous materials, the driver:

Can cross railroad tracks without slowing or stopping.

Needs to slow when approaching railroad tracks, but is not required to stop.

Must stop at railroad crossings before proceeding.

Should never drive over railroad tracks.

A vehicle with tanks that are used to transport hazardous materials must always be stopped before being driven over railroad tracks, even if the tanks are empty.

4. When using mirrors while driving, you should:

Look in the mirrors quickly.

Look in the mirrors for extended periods of time.

Use only the rearview mirror.

Use only the driver’s side mirror.

Focusing on your mirrors for too long can be dangerous because you will have traveled a substantial distance without looking at the road ahead.

5. Texting while driving a CMV is:

Acceptable if the text is work-related.

Acceptable if there are fewer than 10 words in the text message.

Encouraged because it is safer than talking on the phone.

Prohibited.

Texting while driving a commercial motor vehicle is both illegal and dangerous. Manually entering text into or reading text from any electronic device is considered texting.

6. On slippery roads, you should:

Pass vehicles if they aren’t driving the speed limit.

Adjust driving to match the conditions.

Drive on the shoulder.

Accelerate and decelerate frequently.

Make sure to drive slowly and smoothly on slippery roads. Do not pass slower vehicles unless it is necessary to do so. Avoid frequently changing your speed under such conditions.

7. If approaching a railroad crossing that is being approached by a train, you should:

Try to cross the tracks quickly.

Drive around any lowered gates.

Stop and wait for the train to pass before beginning across the tracks.

Never attempt to beat a train to a railroad crossing. It is very difficult to accurately judge the speed of an approaching train. If you come upon a crossing that is being approached by a train, you must stop and wait for the train to pass before you attempt to cross the tracks.
