Arizona Drivers License Practice Test

The correct answer is that the driver already on the highway has the right of way when entering. This rule is designed to maintain a safer flow of traffic on highways, which typically have higher speeds and less frequent stops compared to other roads. Drivers entering the highway must yield to oncoming traffic to avoid collisions. This gives the vehicles already on the highway the opportunity to maintain their speed and ensures that merging maneuvers are conducted safely. It is crucial for drivers to be aware of their surroundings and judge the speed and distance of vehicles on the highway before entering. The other options, including the entering driver, the driver with the largest vehicle, and the fastest vehicle, do not hold validity in traffic laws. The priority is always given to those already on the highway regardless of the size or speed of any vehicles involved.
