Collierville, TN Noise from Specific Sources: Delivery Truck Noise (2026)

Delivery and heavy truck noise in the Town of Collierville is governed by the anti-noise chapter, § 130.022 of the Collierville Code of Ordinances. Division (D) makes it unlawful to operate a motorized vehicle, including cars, trucks, buses, motorcycles, motorbikes, minibikes and go carts, within the corporate limits on private or public property, if it creates noise above the listed limits. Because the rule reaches private property, a loading dock or store lot is covered the same as a street. For trucks and buses over 10,000 pounds, the maximum allowable limit is 87 db(A) measured at 50 feet, or 93 db(A) measured at 25 feet.

Measurement is controlled by division (E). A sound level meter meeting American National Standards Institute standards must be used and kept in calibration, and traffic, aircraft and other transportation noise are not counted unless they interfered with the primary noise being measured. A moving vehicle's reading must be confirmed by a measurement taken with the vehicle stationary, and the driver is required to accelerate the engine to one-half throttle for that reading.

The code lists exempt vehicles. They include ambulances on call, vehicles used as garbage collection trucks while performing duties and loading or processing garbage and debris, fire equipment on emergency call, law enforcement equipment on emergency call, vehicular equipment used to remove trees, brush and undergrowth, and trucks that have been issued permits by the Collierville Police Department. Except for Town of Collierville equipment, every exempt vehicle must still maintain mufflers and related equipment within the section's noise level regulations.

The code also lists, as its own category, the creation of any loud and excessive noise in connection with the loading and unloading of any vehicle or the opening and destruction of bales, boxes, crates and other containers. That language is the closest the Town comes to a delivery-specific rule, and it carries no decibel figure.
