Difficulty: EasyTurning Procedures and Signaling

A driver is traveling on a two-lane road and wishes to make a U-turn. In which of the following scenarios is executing a U-turn illegal due to visibility regulations?

  1. On a curve or hill crest where approaching drivers from either direction cannot see the vehicle within 500 feet.Answer
  2. B
    Across a roadway marked with a single broken yellow centerline on a straight stretch of road.
  3. C
    At an uncontrolled intersection when yielding right-of-way to all oncoming traffic.
  4. D
    When turning left across an unprotected solid circular green traffic signal light.

Answer

Executing a U-turn is illegal on a curve or near the crest of a grade where the vehicle cannot be seen by drivers approaching from either direction within 500 feet.
Traffic safety regulations explicitly prohibit making a U-turn on any curve or near the crest of a hill where the turning vehicle cannot be seen by approaching traffic from either direction within 500 feet. This rule ensures approaching motorists have adequate time to perceive and brake for a vehicle maneuvering across lanes.

Step-by-Step Solution

1
Identify the core safety and visibility requirement for executing U-turns.
Driver visibility must be sufficient for approaching traffic to see the maneuvering vehicle in time to react.
U-turns require crossing across traffic lanes at slow speeds, creating a significant hazard if sightlines are obstructed.
2
Evaluate the visibility threshold established by traffic laws.
Standard motor vehicle codes prohibit U-turns on curves or hill crests where clear visibility is under 500 feet in either direction.
Approaching drivers traveling at highway speeds require adequate stopping sight distance to avoid colliding with a turning vehicle.
