Texas Transportation Code Chapter 551 (the bicycle chapter) is silent on sidewalk riding, so the matter is left entirely to municipalities. Houston Code of Ordinances § 45-302 prohibits riding on sidewalks in the central business district; Austin City Code § 12-1-32 prohibits sidewalk riding in business districts marked by signs; Dallas, San Antonio, and Fort Worth each have their own downtown carve-outs. Outside the marked districts, sidewalk riding is generally allowed in most Texas cities.
Texas's DWI statute (Tex. Penal Code § 49.04) applies only to operators of a 'motor vehicle.' The Penal Code definition (§ 49.01) does not include bicycles, so a cyclist cannot be charged with DWI in Texas. Riders who appear impaired in public can still be arrested for public intoxication under § 49.02, a Class C misdemeanor with a fine up to $500.
White headlamp visible from a distance of at least 500 feet to the front.
Rear requirement
Rear reflector or light
Rear spec
Red reflector visible from 50 to 300 feet when directly in front of motor-vehicle low-beam headlamps, or a red rear lamp visible from 500 feet to the rear in lieu of the reflector.
Tex. Transp. Code § 551.103(c) permits persons operating bicycles on a roadway to ride two abreast. Riders riding two abreast on a laned roadway shall ride in a single lane and may not impede the normal and reasonable flow of traffic; on other roadways riders shall ride single file when traffic conditions warrant.
Bicycles are prohibited on the Interstate system in Texas under TxDOT regulations governing controlled-access highways. The TxDOT Roadway Design Manual and posted on-ramp signage exclude non-motorized traffic; rural 'no reasonable alternative' exceptions, common in Western states, are not in force in Texas.
