In The Sims 3, a curfew is given to children and teenagers to remind them that they need to go home. A child's curfew is 10:00 PM and a teen's is 11:00 PM.
Curfew can't be disabled in any legitimate way, but it does not apply if the child or teen is accompanied by a young adult, adult, or elder. This allows objects such as tents to be used.
Teens will be brought home by the police if they stay out past their curfew. If children stay out past their curfew, they will not be brought home by the police. Instead, they will automatically go home or to the nearest adult family member. This action cannot be canceled.
For The Sims 3 for Windows and Mac OS X (Does not work in Console Versions)
No Curfew Police is a mod that changes the way the curfew feature works.
When a teenager is out during curfew, it gives the pertaining moodlet until a police officer catches the Sim or the teen goes home. When he is caught, he cannot run away from the officer (unless using the testingcheatsenabled true cheat and deleting the officer, Windows and Mac OS X only) and the Sim gets a negative moodlet and a scolding from an Adult (that is able to be canceled) on the home lot.
To prevent getting caught by the curfew, use the "go here with..." action to have teens and children visit a community lot with an adult family member, and try not to stray to lots where it is more difficult for the adult to follow. This is useful when a Sim is trying to gain collectibles or is fishing away from home. If a Sim is at the graveyard mourning a dead family member, he or she doesn't get the positive moodlet for being out after curfew and won't be rounded up while mourning. As soon as the Sim stops mourning, he or she can be rounded up.
- In The Sims 2 and The Sims Stories, teens and children do not have a curfew and there were no time limits for how long they could be on community lots alone.
- Children and teens will be grounded if Generations is installed.
