Summary
Surprise bans loud or unnecessary vehicle engine noise, tire squealing, and unauthorized use of engine-compression (Jake) brakes under Code § 54-2. Running a Jake brake where a sign specifically prohibits it, or otherwise making loud vehicle noise anywhere in the city, is a civil traffic violation, not a criminal offense, unless the driver was avoiding an imminent risk to life or property or was responding to an emergency.

Full Breakdown
Code § 54-2(a) prohibits three specific acts by anyone operating a vehicle anywhere within the city: creating loud or unnecessary engine noise, creating loud or unnecessary noise by squealing or spinning tires, and using an engine-compression braking device (commonly called a Jake brake) at any location posted with a sign notifying motorists that the device is prohibited there. Two affirmative defenses apply to the Jake-brake prohibition: it was necessary to apply the brake to avoid an imminent risk of injury to life or property, or the brake was applied to slow or stop a fire or other emergency vehicle responding to an emergency.
) and article 4. § 28-955, which independently requires vehicles to be equipped with a muffler that prevents excessive noise. Because Section 54-2 applies 'anywhere within the city,' it is not limited to public streets and can reach noise made on private lots, parking areas, or driveways.
Violations & Fines
A vehicle-noise violation is charged as a civil traffic violation, the same category used for speeding and other moving infractions, and is handled through Arizona's civil traffic citation and hearing process rather than criminal court. There is no separate fine schedule specified in Section 54-2 itself; penalties follow the state civil traffic violation procedures referenced in the section, and a driver cited for an unauthorized Jake brake can avoid liability by showing one of the two affirmative defenses built into the ordinance.
