21 true or false: those using a learner's permit have restrictions on when they may drive because alcohol-related crashes are most likely to occur during school hours on a weekday.

This is FALSE.

Explanation:

A learner's permit is a kind of provisional  license which is given to the one who is still "learning" to drive, but still has not obtained a driver's license. Such people do have certain restrictions such as they cannot drive alone and need to be accompanied by 25-year old. They are also not allowed to take specific routes like that of  a school in some states. These are mandatory restrictions and not related to alcohol crashes. Thus, the given statement is False.
