Do I have to take a breath test just because a police officer wants me to?

No, you cannot be forced to take a breath test. However, Texas is an implied consent state, those who are asked to provide a breath test to a police officer with risk having their licenses suspended if they refuse. A blood test, however, can be forced upon you. As this type of test becomes more and more prevalant, new defenses must be incorporated to prevent admission of this evidence.
