Question 15

Heavy rain sharply reduces visibility and traction on a road posted at 65 miles per hour. What does California's basic speed rule require?

  1. Maintain exactly 65 because a posted limit overrides weather
  2. Drive at least 55 so traffic does not slow
  3. Reduce speed as needed to remain reasonable and prudentCorrect answer
  4. Stop in the travel lane whenever rain begins
