Refusing to take a test in Texas will likely result in license suspension. However, you do have a 15-day window to request a hearing for the purpose of preventing your license from being revoked.
The duration of driver’s license suspensions depends on how often you’ve refused or failed a breathalyzer test. If it’s your first refusal, then you may lose your driver’s license for 180 days. If you have a prior DWI conviction or a prior refusal, then your license may get suspended for 2 years.
If you do request a hearing regarding your license suspension, then an administrative hearing will determine if you lose your license and for how long. If you do not request this hearing, then your license will be suspended for the maximum allowable period.
