Curfews are just another way that causes trouble in a teenagers life. Like the driving curfew, it has done more damage than justice. All this curfew does is make teens rush to get home faster and which may cause a wreck. And the same for a teen being home at a certain time. If they're around the age of 13 or 16, a curfew can be alright, just to teach some type of responsibility, plus, teens at that age are quite vulnerable. Once the teen is 16+, there is really no real reason for the curfew. If you can trust them with a care, I'm pretty sure you can trust them enough to get themselves home safely, unless you live in a very bad area.
