Highland, CA Noise from Specific Sources: Delivery Truck Noise (2026)

Two items in § 8.50.050 of the Highland Municipal Code govern delivery and heavy truck noise. Item B covers loading and unloading. It is unlawful to load or unload any vehicle, or to operate or permit dollies, carts, forklifts or other wheeled equipment, in a way that causes any impulsive sound, raucous or unnecessary noise within 1,000 feet of a residence, at a time other than the controlled hours. Those hours are 5:00 a.m. to 10:00 p.m. on any day in the industrial (I) zone and 7:00 a.m. to 10:00 p.m. on any day in all other zones. A loading dock or delivery bay in the City of Highland that sits within 1,000 feet of a home is covered by the rule even when it is in a commercial zone, and the 10:00 p.m. cutoff applies to the noise-making activity rather than to the whole delivery.

Item I covers idling and auxiliary equipment. It applies to any motor vehicle with a gross vehicle weight rating in excess of 10,000 pounds, and to any auxiliary equipment attached to it, including refrigerated truck compressors. The vehicle cannot run for a period longer than 15 minutes in any hour while it is stationary and on a public right-of-way or public space. The only printed exception is when movement of the vehicle is restricted by other traffic. Item I does not carry the controlled-hours framing in practice: it is a duration limit that the section's lead sentence places outside the permitted window.

Related rules sit nearby. Item K bars handling garbage cans, recycling bins or similar objects between 10:00 p.m. and 7:00 a.m., except city-permitted trash collection. Section 8.50.060(K) exempts equipment and facilities of essential public services, including trash collection and public utilities under the Public Utilities Commission.

The city manager, chief of police and their designees enforce Chapter 8.50 (§ 8.50.070). A business that holds a city permit or license and violates the chapter more than twice in any six-calendar-month period can face modification, suspension or revocation of that permit or license at the city manager's discretion (§ 8.50.140).
