Washington Rest Area & Parking Rules
You get 8 hours in any 24-hour period at a Washington rest area (RCW 47.38.020), and sleeping in your vehicle overnight is fine. Washington writes in the carve-out drivers want: a commercial vehicle may park up to one hour beyond a federally mandated rest period. Tents, camping, and shelters are banned. The State Patrol enforces it, and a disabled truck left past 48 hours gets impounded. This is a reference, not legal advice.

Limits, truck parking, and HOS rest
- Time limit: 8 hours in any 24-hour period; commercial trucks may park up to 1 hour beyond a federally mandated rest period
- Truck spaces on I-5 and I-90 fill by evening. Scout ahead on WSDOT's travel map and Washington 511. The state's Jason's Law survey flagged shortages on both corridors, and there's no full statewide real-time truck-parking board yet.
- hosException: yes - RCW 47.38.020 explicitly lets a commercial vehicle park up to one hour past a federally mandated rest period, so being out of hours is a written reason to stay past the 8-hour cap. Welcome centers follow the same 8-hour rule; weigh/inspection stations are for weighing, not overnight parking. Dual lens: statute and posted signs agree at 8 hours.
What overstaying costs
Citation and/or tow. A disabled vehicle left past 48 hours faces mandatory impound (RCW 47.38.020). No fixed dollar overstay fine set in statute.
