CAUTION:
Unlocked doors can be dangerous.

--
Passengers especially children
easily open the doors and fall out of a
moving vehicle. When a door is locked,
the handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.
D
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 your vehicle
whenever you leave it.
D
Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
