Weather, Visibility & EmergenciesStandalone practice
The sun has set, but streetlights still let you see the roadway. What does Idaho require?
Correct answer: Turn on the required vehicle lights
Why
Idaho requires the appropriate vehicle lights from sunset to sunrise. They are also required when people and vehicles cannot be clearly seen 500 feet ahead. Do not rely on street lighting or parking lights alone.
