California Driver License (DMV) Written Practice Test

When changing lanes, it is important to first check your blind spot by looking over your shoulder in the direction you want to move. This will help you ensure that there are no cars in your blind spot that you may not have seen when checking your mirrors. Turning on your signal light is also important to let other drivers know your intentions, but it should not be the first step as it may cause you to merge before you have fully checked for any potential obstacles. Making eye contact with other drivers is a good practice but it should not be relied upon as the sole method of ensuring your safety when changing lanes. Speeding up before entering the next lane is dangerous and can increase your chances of causing an accident.
