Which is a possible restriction of drivers under the age of 18?

Graduated driver licensing rules often restrict young drivers from driving late at night, unless accompanied by a parent or another qualified adult. A restriction from 12:30 a.m. to 5:00 a.m. is a possible example. A weekend-wide ban and requiring two companions are not typical restrictions, and passenger limits usually allow exceptions rather than banning all passengers under 18.
