In Texas, DWI laws consider anyone who is under the age of 21 to be a minor. In Texas , driving on the roads implies that you are giving police officers implied consent to check your breath or your blood for the presence of alcohol or other drugs. This means that just by driving, you are already agreeing that it is ok for an officer to ask you to take a breath or blood test. If you refuse to do so your driver’s license could be suspended for 180 days on the 1st offense and 2 years on the second. If you do not have a driver’s license, then your driving privileges will be suspended the same number of days or years once you become eligible. Now this doesn’t mean you have to take a test, it is perfectly legal, and sometimes smarter to refuse any test that an officer might want you to take.
