Full Breakdown
Hesperia Municipal Code § 16.20.090(H) regulates commercial vehicle parking in residential and agricultural zoned areas, covering trucks and trailers with a manufacturer's gross vehicle weight rating of 26,000 pounds or more. Under subsection H.2.a, no commercial vehicle may be left to idle for longer than five minutes, and air horns may not be sounded. The same subsection bars transferring cargo between commercial vehicles on-site, and prohibits operating refrigeration units within 300 feet of any inhabited place without the occupant's consent. The rule targets the noise and disturbance created by trucks parked at operators' homes, not passenger vehicles or ordinary deliveries.
Violations & Fines
Idling or cargo-transfer violations fall under Hesperia's commercial vehicle parking permit program (§ 16.20.090); permit holders risk revocation, and general code violations are misdemeanors under HMC § 1.12.030 punishable by up to a $1,000 fine.
