Summary
Spokane Valley caps commercial vehicle idling in residential zones at 15 consecutive minutes, or 15 minutes total per calendar day, under SVMC § 9.30.060. The limit covers the R-1 through R-4 and MF-1/MF-2 zoning districts and any street off the City's arterial map. Truck refrigeration units face an overnight curfew too.
No person shall cause a commercial vehicle to idle in any residentially zoned area for more than 15 consecutive minutes, or more than 15 minutes total in any single calendar day.
Full Breakdown
Spokane Valley Municipal Code § 9.30.060 sets a hard time limit on commercial vehicle idling in residential areas: no more than 15 consecutive minutes, and no more than 15 minutes total in a single calendar day. "Residential area" is defined in SVMC § 9.30.020 as the R-1 Single-Family Residential Estate, R-2 Single-Family Residential Suburban, R-3 Single-Family Residential, R-4 Single-Family Residential Urban, MF-1 Multifamily Medium Density Residential, and MF-2 Multifamily High Density Residential zoning districts, and applies on any "residential street," meaning a street or alley not on the City's arterial road map.
"Commercial vehicle" takes the definition in RCW 46.04.140. The same chapter also restricts refrigeration units: SVMC § 9.30.070 bars running a refrigeration unit on a commercial truck or trailer in a residential zone between 10:00 p.m. and 7:00 a.m., except during an actual local delivery. Chapter 9.30 is part of a broader truck-traffic package that also lets the City post "No Trucks" signs closing specific residential streets to trucks with a gross licensed weight of 10,000 pounds or more (SVMC § 9.30.030), with exemptions for government, emergency, utility, and active local-delivery vehicles, plus residents commuting in their own trucks.
Enforcement of the idling limit does not require the owner to be behind the wheel: SVMC § 9.30.040 lets the citing officer issue the citation to the vehicle's registered owner under RCW 46.44.120 if the operator isn't the owner, and the operator may sign the promise to appear on the owner's behalf.
Violations & Fines
Violating the idling limit, the refrigeration-unit curfew, or the "No Trucks" restrictions in Chapter 9.30 SVMC is a Class 1 civil infraction under Chapter 7.80 RCW, per SVMC § 9.30.080. Officers may cite the vehicle's registered owner even when someone else was driving, and the operator can accept the ticket and sign the promise to appear on the owner's behalf.
