Yes, driving with interior lights on is not explicitly prohibited in Maryland, but it may violate §21-1208 of the Maryland Vehicle Law if deemed a distraction under “unsafe operation.” Local jurisdictions like Montgomery County have signaled stricter enforcement post-2026 under updated distracted driving ordinances.
Key Regulations for Driving With Interior Lights On in Maryland
- Distraction Clause (§21-1208): Interior lighting that impairs the driver’s view or distracts other motorists may be cited as “unsafe operation,” a primary offense under Maryland’s distracted driving statute.
- Local Ordinances: Counties such as Prince George’s and Baltimore have signaled alignment with 2026 AAA recommendations, which may classify excessive interior lighting as a primary violation in distracted driving crackdowns.
- Commercial Vehicles (COMAR 11.17.03): Fleet operators must ensure interior lighting complies with federal FMVSS 108 standards; non-compliance risks citations during Maryland State Police roadside inspections.
The Maryland Motor Vehicle Administration (MVA) defers enforcement to officer discretion, emphasizing that interior lights must not compromise visibility or driver focus. While no statewide ban exists, courts have upheld citations under broader distracted driving precedents. Drivers should err on the side of caution, particularly in high-traffic corridors like I-95 or I-495.
