Yes, driving with interior lights on is legal in Washington, provided they do not impair the driver’s visibility or distract other motorists. State law prioritizes visibility and safety, but excessive interior lighting may violate distracted driving statutes. Local jurisdictions, including Seattle and Spokane, enforce stricter nuisance ordinances.
Key Regulations for Driving With Interior Lights On in Washington
- Visibility and Distraction Standards: RCW 46.61.675 prohibits any interior lighting that obstructs the driver’s view or creates a hazard. Courts interpret this as requiring lights to be dimmed or shielded if they interfere with safe operation.
- Local Nuisance Ordinances: Cities like Seattle (SMC 11.44.020) and Spokane (SCC 10.16.020) classify overly bright interior lights as a public nuisance. Violations may result in fines up to $250, enforced by local police.
- 2026 Compliance Shifts: The Washington State Department of Transportation (WSDOT) is drafting updated guidelines for 2026, aligning with federal distracted driving initiatives. Future enforcement may target “excessive” lighting as a primary violation.
Washington’s framework balances driver discretion with safety obligations. While no explicit ban exists, courts and local agencies evaluate cases under existing distracted driving and nuisance laws. Drivers should exercise caution to avoid citations.
