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.
driving while license invalid
DWLI means Driving While License Invailed. Usually when you have an occupational license and your driving out of your hours. It's like driving while your license is suspended but not as bad. The ticket is ridiculously expensive though. In TX it was $576
