Can a Bicyclist Be at Fault for an Accident?

Yes, a bicyclist can be at fault for an accident in Texas because bicyclists are considered vehicle operators and must follow applicable road rules. Fault depends on each party’s responsibility for causing the collision. Under Texas’ 51% modified comparative fault rule, an injured bicyclist or motorist who is more than 50% at fault cannot recover compensation, while those 50% or less at fault may recover reduced damages. Bicyclists can be liable for violations such as failing to signal, riding against traffic, cycling under the influence, or failing to use required lights.

When a bicyclist is harmed in a motor vehicle collision, most people automatically assume that a “negligent” motorist will be held responsible for the accident and any costs associated with the victim’s injuries. After all, bicyclists face higher levels of risk on the road, and drivers legally owe them a duty of care.

However, what many people don’t realize is that this onus is reciprocal – drivers and bicyclists have a shared responsibility to protect each other from undue injury and hazards.

So, when can a bicyclist be held liable for a collision?

Key Takeaways

  • Bicyclists can be at fault: Texas law requires bicyclists to follow applicable road rules because bicycles are considered vehicles.
  • Comparative fault applies: Under Texas’ 51% modified comparative fault rule, those more than 50% responsible cannot recover compensation; those 50% or less at fault may recover reduced damages.
  • Traffic violations can create liability: Examples include failing to signal, riding against traffic, cycling under the influence, passing between cars, or failing to use lights at night.
  • Drivers also have responsibilities: Motorists must yield the right of way to bicyclists because collisions can cause significant or fatal injuries.
  • Fault depends on the circumstances: Liability can be difficult to determine in complex bicycle accidents, making the applicable laws, regulations, and exceptions important when pursuing a civil claim.

Texas’ Modified Comparative Fault Laws

There are approximately 700 bicyclist fatalities in the United States each year. For this reason, many states, including Texas, have enacted laws to protect bicyclists and are even encouraging public road engineers to utilize design strategies that have been proven to reduce accident and fatality rates. Interestingly, only bicycle accidents involving fatalities are officially reported in Texas, meaning that the number of annual injuries is likely far greater than what safety reports and statistics project.

Per Tex. Transp. Code Ann. §§541.201(23); 551.101, a bicycle is a “vehicle,” which means that a bicyclist is required to follow the same road rules as any motorist. When an accident does occur, the question of fault or liability depends on which party was responsible for causing the accident and to what degree. Texas also follows a 51% modified comparative fault rule, which means that an injured bicyclist or motorist cannot recover compensation if they are found to be over 50% at fault for the collision. However, they can still recover compensation – if at a reduced amount – if they are found to be 50% or less at fault for the accident.

A bicyclist in Texas can be held accountable for the following actions:

  • Failing to follow traffic laws
  • Cycling under the influence of drugs or alcohol
  • Failing to ride with oncoming traffic
  • Incorrectly signaling or failing to signal at all
  • Failing to use a bike lane when traveling slowly
  • Passing in-between cars
  • Using limited state access highways without a bike path
  • Failing to use lights (such as a front light) at night

At the same time, drivers must yield the right of way to bicyclists because motor vehicles are capable of inflicting significant and even fatal damage. Because it can be difficult to determine liability after a complex bicycle accident case, it’s critical that both motorists and bicyclists seek legal representation to understand the various laws, regulations, and exceptions that can influence the outcome of a civil lawsuit.
