Austin, TX Parking Rules: Commercial & Oversized Vehicles (2026)

Section 12-5-9 of the Austin City Code sets a weight line at 9,000 pounds. Subsection (A) says a person may not park a motor vehicle with a gross vehicle weight greater than 9,000 pounds on a public street with a speed limit of 30 miles per hour or less. Two things trigger the rule together: the vehicle's gross vehicle weight and the posted speed limit of the street. A vehicle at exactly 9,000 pounds is not covered, because the text says greater than 9,000 pounds. A street posted above 30 miles per hour is also outside this section.

Subsection (B) lists two exemptions. The restriction does not apply to a motor vehicle engaged in loading, or unloading, of materials or property, and it does not apply to a motor vehicle of a public utility making emergency utility service repairs. A delivery truck that stops at the curb to unload is therefore outside § 12-5-9, but a heavy truck left on the street overnight is not.

The ban sits beside other Chapter 12-5 rules that reach work vehicles. Section 12-5-5 defines a commercial vehicle as a motor vehicle designed, used, or maintained primarily to load, transport, and unload material or property, and requires the enterprise name on each side in letters at least two inches high and one inch wide. Section 12-5-10 prohibits parking a trailer or other non-motorized equipment designed to be towed on a public street. Section 12-5-11 caps a self-propelled motor home at 72 continuous hours on a public street or alley. Section 12-5-12 requires a permit from the director of the Austin Transportation and Public Works Department before a commercial vehicle loads or unloads from a metered space, commercial loading zone, or curb-side travel lane.

Responsibility follows the registration. Under § 12-5-1, a person may not park in violation of the chapter or allow a vehicle owned by the person or registered in the person's name to be parked in violation, and proof of registration is prima facie evidence the person committed the violation. Under § 12-5-57, the registered owner is liable to the City for parking violations unless an exception applies, such as the operator being named in the citation or proof that the vehicle was sold before the violation.
