No doubt, the Texas DWI laws are very stringent and punitive. These laws are imposed on people who are caught driving while intoxicated. As generally seen, most of the DWI or DUI laws refer to those under the age of 21 operating a motor vehicle with detectable alcohol in the body. Here we should note that one must be proved intoxicated to obtain a conviction. The person must be in the state of intoxication while operating a vehicle in a public place, such as highways or general roads.
