Arizona Drivers Permit Pactice Exam

When merging onto a freeway, what speed should you be driving?

1. At a speed limit of 25 mph

2. At least 10 mph below the traffic speed

3. At or near the speed of traffic

4. Always keep at a constant speed of 30 mph

The correct answer is: At or near the speed of traffic

Merging onto a freeway requires aligning your speed with the flow of traffic for safety and efficiency. When you drive at or near the speed of traffic, you minimize the risk of collisions and help maintain the smooth operation of the highway. Freeway traffic typically moves at higher speeds, and entering at a similar speed allows you to merge seamlessly without forcing other drivers to adjust their speed dramatically. Driving significantly faster or slower than the prevailing traffic can create dangerous situations. For instance, going too slowly can disrupt the flow and cause frustration among other drivers, while exceeding the speed can lead to a loss of control. Therefore, matching your speed to that of the current traffic is crucial for safe merging.
