Difficulty: MediumFreeway, Highway, and Expressway Driving Rules

You are traveling in the right lane of a multi-lane freeway where the posted maximum speed limit is 65 mph. Heavy rainfall begins, significantly reducing visibility and causing water to pool on the road surface. Under traffic laws, which action is legally required?

  1. Reduce your vehicle speed below 65 mph to a rate that is safe and prudent for the hazardous weather conditions.Answer
  2. B
    Maintain the posted 65 mph speed limit because maximum posted limits remain legally enforceable baseline speeds in all weather.
  3. C
    Cross over the solid yellow line onto the left paved median shoulder to pass slower-moving traffic.
  4. D
    Accelerate and execute rapid passing maneuvers within 100 feet of upcoming freeway interchange ramps to clear heavy traffic quickly.

Answer

Reduce your vehicle speed below 65 mph to a rate that is safe and prudent for the hazardous weather conditions.
The correct answer specifies reducing vehicle speed to match conditions. The Basic Speed Law dictates that no person shall drive at a speed greater than is reasonable or prudent under existing weather, visibility, and road conditions.

Step-by-Step Solution

1
Identify the driving conditions and posted limits
The posted speed limit is 65 mph, but heavy rain has reduced visibility and road traction.
Environmental hazards change safe operating parameters.
2
Apply the Basic Speed Law
Drivers are legally obligated to adjust their speed below posted limits when road, weather, or traffic conditions make higher speeds unsafe.
The posted limit represents the maximum speed permitted under ideal driving conditions, not adverse weather.
