Step-by-step explanation:
When driving, you should make a SPECIAL point of checking traffic behind you in certain situations. One such situation is when there is an emergency vehicle or police car behind you with flashing lights and sirens. In this case, you should check your mirrors frequently to ensure you can safely pull over to the side of the road and let the emergency vehicle pass.
Another situation where you should check traffic behind you is when you need to change lanes. Before changing lanes, it's important to look over your shoulder and check your blind spot to make sure there are no cars approaching from the rear.
Lastly, you should check traffic behind you when you are preparing to stop or slow down. This is important to ensure that the cars behind you have enough time to react and avoid a collision.
