FAQ about Automatics:-
In a automatic car when you stop at lights or at a give way sign do you need to put the car into "park" or "neutral" or put the handbrake on in either of these , or just brake?
From time to time you will stop in traffic. On these occasions you need to make sure that the car is secure. Whether driving a manual or automatic, it's a good idea to use the handbrake to secure the car when you stop for more than a moment. This helps to prevent the car from being shunted forward if hit from behind.
In an automatic it's even more important to use the handbrake; if you are hit from behind the car will try to take off! Stay in drive so that you are ready to move and apply the handbrake firmly.
If waiting a long time, apply the handbrake and then select neutral. This removes the chance of 'creep' if the handbrake is not securely applied.
When parking use the 'park' position as soon as you stop. This locks the transmission.

I'm learning how to drive an automatic :D
