Bicycles are considered vehicles in Texas. That means cyclists must follow the same rules of the road as cars, with a few exceptions as designated in the Texas Transportation Code. Here is a summary of Texas bicycle-related laws put together by the League of American Bicyclists.
All laws mentioned below were current as of August 2012 and may be subject to change.
Safe Passing Laws
Texas does not have a law that sets a specific distance for a motor vehicle overtaking a bicycle. The overtaking of a bicycle by a motor vehicle, or vice versa, is governed by general traffic laws and, in most circumstances, such overtaking must be done to the left at a safe distance.

Helmet Law
Texas has no helmet law. It is legal for all persons of any age to operate a bicycle without wearing a helmet unless otherwise provided by a municipal regulation.
However, Texas has designated April as Child Safety Month which, amongst other things, promotes ways to reduce accidental injury and death through the use of bicycle helmets.

Bicycling Under the Influence
Texas's law prohibiting driving while under the influence of alcohol or other controlled substances is written so that it applies to motor vehicles and therefore does not directly apply to bicyclists. Nevertheless bicycles should not be operated while intoxicated.

"Idaho Stop" and Vehicle Detection Errors
Texas does not provide any modifications to the requirement to come to a complete stop when directed to stop by traffic control devices and does not authorize bicyclists to disobey traffic lights that fail to detect bicyclists.

Authorization for Local Regulation of bicycles
Texas provides that its state traffic laws shall not prevent a local authority, with respect to a highway under its jurisdiction and in the reasonable exercise of the police power, from the operation and requiring registration and licensing of a bicycle or electric bicycle, including payment of a registration fee.
In addition, a governing body of a municipality may restrain or prohibit the firing of firecrackers or guns, the use of a bicycle or similar conveyance, the use of a firework or similar material, or any other amusement or practice tending to annoy persons passing on a street or sidewalk.
