You see a vehicle approaching from the rear. When you check your mirror again to change lanes, you no longer see the vehicle. You should:

Check your outside mirror to see if the vehicle is in your blind spot.
Turn your signal on and change lanes slowly.
Look over your shoulder to be sure the vehicle isn’t in your blind spot.
All of the above.
Explanation

In order to change lanes safely, it is important to look in all your mirrors and then turn your head and look over your shoulder to check for vehicles in your blind spot. In this example, the vehicle that you initially saw in your rearview mirror may have moved into your blind spot while you were looking away. Before changing lanes, always look over your shoulder in the direction you plan to move and make sure that no vehicles are in your blind spot.
