Arizona Driving Permit Written Practice Test

The best approach when uncertain about the safety of changing lanes due to a blind spot is to refrain from making the maneuver until you can be confident that it is safe to do so. Blind spots are areas around your vehicle that cannot be easily seen through mirrors, making it crucial to double-check for other vehicles or obstacles before changing lanes. Taking the time to ensure that the way is clear not only keeps you safe but also promotes safety for other drivers on the road.

Proceeding slowly while assuming there is no danger could lead to a collision since it disregards the importance of actively checking your surroundings. Simply signaling without checking does not ensure your safety either, as it could result in a dangerous situation if another vehicle is in your blind spot. Rolling down the window is impractical and does not effectively help in assessing the situation, as it does not provide a better view of the blind spot.

Safety first: wait until you are completely assured that it is safe to change lanes.
