- Entry Level Driver Training Extreme Driving Conditions Questions and Answers Flashcards

When driving a CMV in heavy rain, how much should you reduce your speed?

Answer: Reduce speed by about one-third

In heavy rain, you should reduce speed by about one-third. For example, if the normal speed is 60 mph, slow down to 40 mph to maintain safe stopping distance.

What is the most dangerous time for reduced traction when rain begins?

Answer: During the first few minutes of rain

The first few minutes of rain are most dangerous because water mixes with oil and grease on the road surface, creating an extremely slippery film before it washes away.

When driving in fog, which lights should you use?

Answer: Low beams or fog lights

Low beams or fog lights should be used in fog. High beams reflect off fog particles and create glare that actually reduces visibility.

What should you do if you experience a blowout on an icy road?

Answer: Stay off the brake and gradually slow down

On icy roads, braking hard or steering sharply after a blowout will likely cause a skid. The safest response is to stay off the brake and let the vehicle slow gradually while maintaining steering control.

When driving in extreme cold, why is it important to keep the fuel tank as full as possible?

Answer: To prevent fuel line freeze-up from condensation

A partially empty fuel tank allows moisture to condense on the tank walls, which can freeze and block fuel lines in extreme cold.

What is the recommended following distance in severe weather conditions?

Answer: 7 seconds or more

In severe weather, following distance should be increased to at least 7 seconds or more to account for significantly longer stopping distances on slippery surfaces.
