NHSA Module 9 Practice Test

Which scenario reduces the risk of an alcohol-related crash?

Two people share driving responsibilities. Only one person drinks a little. A designated driver remains sober throughout. Everyone drinks and no one drives.

Correct Answer:

A designated driver remains sober throughout.

Explanation:

When aiming to reduce alcohol-related crash risk, the key is ensuring the driver is sober. A designated driver who remains sober throughout the outing is best because they can drive with full alertness, quick reaction times, and clear judgment, keeping everyone in the vehicle safe. Sharing driving duties can help only if both drivers are completely sober at the moment of driving, which isn’t guaranteed. If the one who drinks drives, impairment still risks a crash. Having everyone drink and no one drive avoids an alcohol-impaired crash, but it isn’t a practical or reliable plan for getting home safely. So, the sober designated driver provides the most consistent safety benefit.
