Arizona Driving Permit Written Practice Test

Making U-turns on a freeway is generally prohibited due to safety concerns and the high-speed nature of these roads. Freeways are designed for continuous traffic flow, and allowing U-turns would create hazards, including sudden stops or slow-moving vehicles in fast-moving lanes. The design of freeways, which typically lacks intersections and has limited access points, further emphasizes the importance of maintaining consistent traffic flow without abrupt maneuvers like U-turns.

The other options involve actions that may be regulated differently but are not outright prohibitions on the freeway. For example, driving in the left lane is allowed as long as it's for passing slower traffic, and you are required to use headlights during certain conditions or at night. Similarly, exceeding the speed limit is illegal on all roads, including freeways, but is not specifically a unique restriction to freeways alone.
