A DWI means you are driving while intoxicated. It can be intoxication with drugs or with alcohol. The penalty can be quite severe including losing your license.
Class C for DWLI with insurance Class B for DWLI with no insurance or prior DWLI conviction Class A if DWLI and cause a crash with serious bodily injury
That depends on what you mean. If you mean "how long can I be arrested for DWLI" then the answer is "as long as you're driving on an invalid license or privilege." DWLI 1st is a Class B Misdemeanor. DWLI beyond the first is a Class A Misdemeanor. Misdemeanors in Texas generally have a statute of limitations of 2 years - meaning that a department or court may bring charges within 2 years of the date of the offense. Hope this helps.
