Observation, Speed & SpaceStandalone practice
You are driving at night on a dark, unlit highway with your headlights on. Which rule should limit your speed?
A blue car travels on an unlit road with a limited area visible in its headlight beam.
Correct answer: Keep a speed that lets you stop within the distance your headlights light clearly.
Why
Headlights let you see clearly only about 250 feet ahead. The manual warns that above about 55 mph on a dark road, you cannot stop within that lit distance. Wyoming law requires a reasonable speed for the conditions, so slow down when you cannot see far and watch for wildlife.
