Implications for Personal Injury Law

Understanding Chapter 545 is particularly important in personal injury cases. For instance, if you’re involved in an accident where a driver failed to yield right-of-way, knowing the specific statutes can help establish liability. At Ryan Orsatti Law, we specialize in plaintiff personal injury law and can help you navigate these complex legal issues.

Case Example: Failure to Yield

Consider a scenario where a driver fails to yield at an intersection and causes a collision. According to Section 545.151, the driver must yield the right-of-way to any vehicle that has entered the intersection from a different highway. Failure to do so can be used as evidence of negligence in a personal injury lawsuit.

Comparative Negligence in Texas

It’s also important to understand Texas’s comparative negligence rule, which can affect the outcome of your case. Even if you were partially at fault for the accident, you might still recover damages, though they may be reduced by your percentage of fault. This principle is outlined in Section 33.001 of the Texas Civil Practice and Remedies Code.


Navigating the intricacies of Texas Transportation Code Chapter 545 can be daunting, but it’s essential for ensuring safety and understanding your rights and responsibilities on the road. Whether you’re a driver, pedestrian, or involved in a personal injury case, knowing these laws can make a significant difference.
