Full Breakdown
Sec. 34-365 lists specific acts the city treats as loud, disturbing or unnecessary noise regardless of a decibel reading. Subsection (1) bars sounding a horn or signal device on any automobile, motorcycle, bus or other vehicle while it is not in motion, except as a genuine danger signal, and separately bars creating an unreasonably loud or harsh sound with a signaling device or sounding it for an unnecessary or unreasonable length of time. Subsection (5) prohibits operating an automobile, motorcycle or vehicle that is so out of repair, or so loaded, that it creates loud or unnecessary grating, grinding, rattling or other noise, covering vehicles with failing exhaust systems, loose parts or overloaded beds.
Subsection (8) flatly bans using an engine-exhaust braking system, the compression-release "Jake brake" that converts diesel engine power into an air compressor to slow a vehicle, while operating a motor vehicle anywhere in the city, with no time-of-day carve-out, a rule with real bite given Baytown's heavy petrochemical and highway truck traffic. These specific prohibitions work alongside the general noise ban in Sec. 34-362 and the decibel ceilings in Sec. 34-363, but none of the three vehicle acts here require a meter reading to support a citation.
Violations & Fines
Sounding a horn while parked outside a true emergency, driving a vehicle so out of repair it grinds or rattles, or using an engine-exhaust brake anywhere in the city are each specific violations of Sec. 34-365 that Baytown Police can cite without a decibel measurement. Conviction carries the general penalty fine under Sec. 1-14, up to $500, and each day a violating condition continues counts as a separate offense.
