Board Certified in Personal Injury Trial Law
The Texas Board of Legal Specialization, which is a State of Texas Organization, certifies lawyers to be Board Certified in Personal Injury Trial Law (and other specialties). There are only 1800 lawyers out of over 100,000 in the entire state that are Board Certified in Personal Injury Trial Law. In order to obtain the certification you have to have tried 10 jury trials as lead counsel, pass a written 1 day test, and obtain the recommendation of 5 Judges and other lawyers.
Negligence is defined in Texas law (and most other states) as the failure to do what a reasonable person would have done under the same or similar circumstances, or doing what a reasonable person would not have done under the same or similar circumstances (such as hitting the accelerator instead of the brake). You have to have a legal duty to the other person such as to drive safely and not hit them. The person is entitled to damages caused by your breach of the duty to drive safely, and not hit them.
Texas is a comparative fault state. If you are found 51% Negligent in Texas (and 32 other States) you get zero.
