Point #11 is "Count 1-2-3 Delay After the Car Ahead Starts to Move".

What is the safe thing to do when the light turns green and the car ahead starts moving? Simply count “one-two-three delay” then start to move.

This automatically gives you 2-4 seconds following time and allows you time to stop if the car ahead suddenly and unexpectedly comes to a halt. You’re re-establishing your space cushion.
