crash is increased if the
doors are not locked. So, all
passengers should wear
safety belts properly and the
doors should be locked
whenever the vehicle is
driven.

unlocked vehicles may be
unable to get out. A child can

vehicle whenever leaving it.

through an unlocked door
when you slow down or stop
the vehicle. Locking the doors
can help prevent this from
happening.
