It is noon, and rain is falling hard enough that you need your windshield wipers to see. What does Missouri law require about your headlights?
Correct answer: Turn them on while you need the wipers.
Why
In rain, headlights matter as much for being seen as for seeing: gray light and road spray make an unlit car hard to spot, especially in mirrors. A simple habit keeps you legal: whenever your wipers go on, turn your headlights on too. Lights are also required from a half hour after sunset until a half hour before sunrise.
