the vehicle in a 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.
.Young children who get into unlocked vehicles
may be unable to get out. A child can be
overcome by extreme heat and can suffer
permanent injuries or even death from heat
stroke. Always lock the vehicle whenever
leaving it.(Continued)

unlocked door when you slow down or stop
the vehicle. Locking the doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
