Is Using Interior Lights While Driving Illegal?: 1 Minute to Understand Car Light Regulations

Whether you can legally use interior lights while driving largely depends on your location. In many regions—including most states in the US—there is no specific law making it outright illegal to have your dome or cabin lights on while driving. However, if the interior lighting is bright enough to distract you, impair your line of sight, or obscure your view of the road, law enforcement could potentially cite you for unsafe driving due to distracted driving or impaired visibility. Police officers may stop you if they believe the light causes a hazard, especially during nighttime.

While it isn't strictly against the law, using interior lights while driving at night is often discouraged. The glare can reflect off your windshield, reducing your ability to see clearly and increasing the risk of an accident. If you need to read directions, search for an item, or attend to children in the backseat, it's best to pull over safely before turning on the lights.

As an interior designer, I always consider how both aesthetics and functional safety come together. When planning your car’s interior or even when thinking about interior lighting design at home, it’s about balancing comfort, utility, and safety. Choosing subdued, well-placed lighting (like low-level footwell LEDs) can provide just enough illumination without impairing night vision, which is a principle you can also apply to your home or workspace lighting for comfort and efficiency.

Tips 1:

If you must use interior lights while on the road, opt for dimmer, downward-facing options to minimize reflections and distraction. Consider using task lights, just as you would select ambient versus task lighting for different zones in a room.
