When must high beams be changed to low beams for an approaching vehicle?
Correct answer: At least 500 feet before reaching it.
Why
Use low beams within 500 feet of an approaching vehicle so glare does not blind its driver. When following another vehicle within 300 feet, use a permitted lower beam rather than high beams. Dim sooner when needed to avoid glare.
