In Texas, you usually have two (2) years from the date of incident to file a personal injury claim before it is barred by the statute of limitations. There are exceptions to this 2-year time limit in Texas, for minors and others. Further, other states have different time limits, and the limit that applies is typically for the state in which the accident occurred.
The safest course of action for someone injured in a car wreck, truck wreck, slip and fall, or any other type of accident is to consult with a personal injury attorney.  This will help ensure that you do not miss the applicable limitations period.  Moreover, it will ensure the right investigations are conducted, and the proper steps are taken to preserve the evidence, photos, witness statements, and records needed to successfully pursue your claim.
