You always have the right to refuse to give a sample of your breath or blood. However, many agencies are now set up to obtain an expedited search warrant to obtain a sample of your blood. If you have been arrested in Texas, you impliedly consented to being tested when you obtained a driver license. This is the law of implied consent. What this means to you is that should you refuse to give a sample of your breath, the State of Texas is able to move to suspend your driver license or your privilege to drive in Texas. Nevertheless, should you consent to give a sample of your breath, and the machine shows you are over the legal limit, your license or privilege to drive could be suspended—although a suspension would be for a shorter period of time.
