It depends on the age of the teenagers. Young teens who are ages 13-16 should definitely have a curfew. There are some kids who just shouldn’t be out at certain times of the night. Most 16-year-olds are just getting a license, which means it’s restricted, which means they have to be home by 9 anyway. However, the 16-year-olds who have their full licenses should be home at a certain time still. Most 17-year-olds are seniors in high school, so the curfew should be nearly dissolved for them.
