If you are on a bicycle, you are required to ride with traffic as Texas Transportation Code considers bicycles vehicles. That means a person on their bike has the same rights and responsibilities as those in vehicles. The only exception is if a contra-flow bike lane is provided, allowing people on bicycles a travel lane that goes against traffic. If you are a pedestrian, and there is a sidewalk, you can walk either with or against traffic. If no sidewalk is present, then State law states that you must walk against traffic.
