Answer 2

. Check your mirrors more often. Drivers should be checking their mirrors every five to eight seconds and then again when slowing or stopping. When coming to a stop at a traffic light or stop sign, always look in the rearview mirror to be sure vehicles behind you are also stopping. When traffic begins to slow or stop on the highway, always check your mirrors to be sure traffic is stopping behind you. You can never tell whether the driver on your rear bumper (or tire, if you’re a rider) is texting just as the vehicles in front of you are stopping.

3. Stay focused on your driving. There may not have been any vehicles behind you when you initially stopped, but they could be rushing up behind you as you sit and wait. It is not inconceivable that one of those drivers has been distracted by a cellphone. This has happened to me. Because I had left myself an escape route, I avoided being hit by that preoccupied driver.

4. As you slow to a stop, identify an escape route. Think of the shoulder, sidewalk, curb lane, left turn lane or any other safe route where you can get out of the way of a charging vehicle.

5. Never rush up to a stop sign or red light. Always slow gradually and this will force the vehicle behind you to also slow more gradually. If you rush up to a red light and then brake hard, the driver behind you may not react too swiftly. The advantage is the light may change to green before you get to it and you may not have to brake at all. Look farther up the road to spot traffic stopping long before the vehicle in front of you slams on its brakes. This will give you the time to brake sooner and gentler, which will force the vehicles behind you to brake sooner, minimizing drivers behind you panic-braking and possibly plowing into you.
