Question 1

When driving a CMV through a flooded roadway, what is the safest action to take?

Accepted Answer

Avoid the flooded area entirely and find an alternate route

Answer

You should never attempt to drive through flooded roadways in a CMV. The depth and current of floodwater are difficult to judge, and even shallow water can sweep a vehicle off course or hide washed-out road surfaces. Finding an alternate route is always the safest choice.

Question 2

Which of the following is a warning sign that a road surface is likely to be icy?

Accepted Answer

Pavement appears dark and wet after temperatures have dropped below freezing

Answer

Black ice forms when pavement looks dark and wet but the temperature is at or below freezing. Unlike snow, black ice is nearly invisible and provides almost no traction warning. Drivers must be especially alert when road surfaces appear wet during or after a temperature drop below 32°F.

Question 3

What is the primary risk associated with driving a CMV through a highway crosswind zone?

Accepted Answer

Loss of vehicle control or trailer sway

Answer

Strong crosswinds can cause trailers to sway and push the vehicle out of its lane, potentially leading to a rollover or jackknife. High-profile vehicles like tractor-trailers are especially vulnerable. Drivers should reduce speed, maintain a firm grip on the wheel, and be alert to wind advisory signs.

Question 4

When descending a steep grade in icy or snowy conditions, what braking technique is most appropriate for a CMV equipped with a manual transmission?

Accepted Answer

Downshift to a lower gear before the descent and use controlled, steady brake applications

Answer

Selecting a lower gear before beginning a steep descent allows engine braking to assist in speed control and reduces reliance on the service brakes. On slippery surfaces, smooth and controlled brake applications help prevent wheel lockup and loss of steering. Coasting in neutral is especially dangerous as it removes engine braking entirely.

Question 5

During a severe thunderstorm with high winds, a CMV driver spots a funnel cloud approaching. What is the recommended action?

Accepted Answer

Abandon the vehicle and seek shelter in a low-lying ditch away from the truck

Answer

A CMV cab offers very little protection from a tornado. Overpasses can actually concentrate wind speeds and create deadly debris traps. The safest action is to leave the vehicle, move away from it, and lie flat in a low-lying area such as a ditch, protecting your head.
