Arizona Driving Permit Written Practice Test

How should you enter and exit a highway to ensure safety and traffic flow?

1. Yield to vehicles already on the highway

2. Back up if you miss an exit

3. Change lanes suddenly to make an exit

4. Speed up significantly when merging

The correct answer is: Yield to vehicles already on the highway

Entering and exiting a highway requires careful consideration to ensure the safety of yourself and others on the road. Option B, back up if you miss an exit, should not be chosen because it is illegal to back up on a highway. Option C, change lanes suddenly to make an exit, should not be chosen because it can disrupt the flow of traffic and potentially cause accidents. Speeding up significantly when merging, option D, can also be dangerous as it requires other drivers to adjust their speed and can lead to collisions. Option A, yielding to vehicles already on the highway, is the safest and most courteous approach as it allows for a smooth flow of traffic and avoids potential accidents.
