If you were hurt in a car accident, there are several factors that could impact the strength of your personal injury case:

1. Liability: To have a successful personal injury case, you need to be able to show that the other driver was at fault for the accident. This might involve proving that they were distracted, driving under the influence, or breaking the law in some other way.

2. Injuries: The severity of your injuries will play a role in the value of your personal injury case. If you've suffered significant harm, you're likely to have a stronger case.

3. Insurance coverage: The availability of insurance coverage can also impact your case. For example, if the other driver was uninsured or underinsured, you may need to look to your own insurance coverage for compensation.

4. Evidence: Gathering evidence can be critical to the success of your personal injury case. This might include photographs of the accident scene, eyewitness statements, and medical records documenting your injuries.

5. Statute of limitations: In Texas, you generally have two years from the date of the injury to file a personal injury lawsuit.

It's also important to keep in mind that personal injury cases can be complex and often require the assistance of a knowledgeable attorney. An attorney can help you understand your legal rights and options, and can represent you in negotiations with the insurance company or in court, if necessary.
