Question: 1 / 400

What should a CDL driver do if they feel drowsy while driving?

Turn up the radio

Keep driving to reach the destination quickly

Pull over safely and take a break

When a CDL driver feels drowsy behind the wheel, the most appropriate and safe action is to pull over safely and take a break. Drowsiness significantly impairs a driver’s ability to concentrate, react quickly, and make sound judgments, just as alcohol does. Taking a break allows the driver to rest, rejuvenate, and be more alert when they continue driving.

Continuing to drive while drowsy increases the risk of accidents, as fatigue can result in slower reaction times and lapses in attention. The other choices, such as turning up the radio or ignoring the drowsiness, do not address the core issue of fatigue and can lead to dangerous situations on the road. Seeking a safe place to stop and rest is the best course of action to ensure the safety of the driver and others on the road.
