We’ve had a few really foggy mornings lately, and it got me thinking about folks who still don’t know how to properly use their headlights in that situation. That led me to think about the actual legality of headlight usage in Indiana.

What I found might come as a surprise to a lot of folks – and a lot of drivers may be accidentally breaking the law without even realizing it, just by how they use (or don’t use) their headlights.

Think back to when you first learned to drive. You were probably focused on parallel parking and not hitting the curb. But do you remember anyone clearly explaining when you’re supposed to use your headlights – and when you’re not? It feels like common sense, but we all know common sense doesn’t always come standard.

What Indiana Law Says About Headlights

So, let’s keep it simple and keep it legal. Here’s what Indiana law actually says about headlights, high beams, and hazards:

  • Headlights must be on from sunset to sunrise.
  • Headlights must also be on if you can’t see at least 500 feet ahead of you.
  • High beams must be dimmed when oncoming traffic is within 500 feet.
  • High beams must also be dimmed when you’re following within 200 feet of another vehicle.
  • Hazard lights are only allowed while driving to signal an emergency.
  • Hazards can also be used for a disabled vehicle along the roadway.

High Beams And Hazard Lights Rules

Now, what about some of those everyday situations? Flashing your brights at another driver – whether you’re reminding them to turn theirs on, dim their brights, or even warning about police – generally isn’t illegal. And using headlights in rain, snow, or fog? It’s definitely smart and safer, but surprisingly, it doesn’t appear to be specifically required by law unless visibility drops below that 500-foot rule.

Next time you’re heading out, take a second to think about how and when you’re using those headlights. And hey, if you’re feeling ambitious, the Indiana Driver’s Manual is only 84 pages – it could make for some good bathroom reading!

Rejected License Plates by the Indiana BMV in 2025

Since the start of the year, over 700 personalized license plate requests have been denied in Indiana. Many were too vulgar to include on this list, but you might get a good laugh at some of the best ones that were rejected.
