Summary
Fullerton caps diesel truck idling at five minutes under FMC § 8.30.060, matching the state's 13 C.C.R. § 2485 anti-idling rule. Any diesel-fueled commercial vehicle rated over 10,000 pounds GVWR that stops, stands or parks on a public or private roadway in the city must shut its primary engine down after five minutes. First-offense fines start at $300 and rise to $750 for repeat violators.
§ 8.30.060 PROHIBITION OF IDLING DIESEL HEAVY VEHICLES.
(A) General prohibition. It shall be a violation for diesel-fueled commercial motor vehicles that operate in the state with gross vehicular weight rating of greater than 10,000 pounds that are or must be licensed for operation on highways parked or standing on any public or private roadway within the city to fail to comply with the following.
(1) Prohibition of idling diesel heavy vehicles. No vehicle subject to 13 C.C.R. § 2485(b), shall stop, stand or park in violation of 13 C.C.R. § 2485(c) by idling the vehicle's primary diesel engine for more than five minutes unless exempted in 13 C.C.R. § 2485.
Full Breakdown
060 folds the state's diesel idling limit directly into city law. § 2485(c). § 2485(c)(3) is flatly prohibited, not just time-limited. Enforcement is not left to one agency: the ordinance names the California Air Resources Board, any peace officer under Cal. Penal Code § 830 and their departments (including parking control personnel), and local air pollution control or air quality management districts as authorized enforcers. A driver or operator who is ordered by a peace officer to abate an idling violation and fails to do so commits a separate violation under division (C).
The rule was adopted with the city's 2010 truck-route package under Ordinance 3145 and amended by Ordinance 3180 in 2013, placing it alongside Fullerton's commercial-vehicle parking and interstate-truck-terminal rules in the same chapter.
Violations & Fines
Violating the five-minute idling limit costs $300 for a first offense, $500 for a second and $750 for each subsequent offense by the owner, operator or both. Unapproved auxiliary power system use is a flat $300 penalty each time it occurs. Ignoring a peace officer's order to abate the violation adds a separate $500 penalty. Penalties are infractions, enforceable through Fullerton's administrative citation process under FMC Chapter 1.10.
