No, driving with interior lights on is not explicitly prohibited in Washington D.C. under the D.C. Municipal Regulations (DCMR) or the D.C. Code, but it may violate broader traffic safety statutes if deemed a distraction under D.C. Official Code § 50-2201.04, enforced by the D.C. Department of Transportation (DDOT). Local law enforcement retains discretion to cite drivers under reckless or unsafe operation provisions if interior lighting impairs visibility or distracts other motorists.
Key Regulations for Driving With Interior Lights On in Washington D.C.
- Distraction Statutes: Interior lights may violate D.C. Code § 40-611, which prohibits operating a vehicle in a manner that endangers others, as excessive interior illumination could distract drivers or reduce reaction times.
- DDOT Enforcement: The D.C. Department of Transportation (DDOT) interprets interior lighting as a potential traffic hazard under DCMR Title 18, § 1201.1, particularly in high-traffic zones like downtown or near Metrobus stops.
- 2026 Compliance Shifts: Pending updates to DCMR Title 18 (expected 2026) may formalize restrictions on non-essential interior lighting to align with Vision Zero safety goals, per DDOT’s 2024 Traffic Safety Action Plan.
Local courts have historically upheld citations under general safety statutes when interior lighting contributes to accidents or near-misses. Drivers should exercise caution, as ambiguity in the law grants officers latitude to issue warnings or fines.
