Defensive driving is designed to heighten your awareness
of everything happening around you while driving.
If you start developing these habits early and realize
that every time you get in a car there is risk involved,
you increase your chances that you won't be involved
in a colision.
Start practicing now by checking your mirrors constantly.
Always be aware of what is on your right, your left
and behind you.
Check the road ahead. What is on the horizon, what
is happening in front of the car ahead of you.
Learn to make eye to eye contact with drivers and pedestrians.
That way you know they see you.
Look at the front wheels of the cars parked on the
side of the road. If you see a car with the wheels turned
to the left, is it going to suddenly pull out?
Of course you can also just drive around in a daze,
fool with the radio, use the mirrors for checking your
hair etc. and the rest of us will pay for it with higher
insurance rates, but you may pay with your life.
