Being pulled over by a police officer can be a stressful and troubling experience, regardless of the possible violations that a driver may be charged with. Those who are pulled over on suspicion of drunk driving may be looking at serious penalties if they are arrested on DWI charges. A DWI conviction can result in significant fines, time in prison, and the loss of one’s driver’s license. Because of this, drivers may wonder about their options when an officer asks them to take a breathalyzer test that will measure the alcohol in their system. By understanding whether these tests can be refused and the potential consequences of doing so, drivers can make the right decisions that will help them minimize the possible penalties they may face.
Implied Consent, Roadside Breathalyzer Tests, and Other Chemical Tests
Texas, like most states, uses the principle of “implied consent” when addressing permission to take chemical tests of a person’s blood alcohol levels. According to the state’s laws, a person who is arrested based on the suspicion that they have operated a motor vehicle on a public road while they were intoxicated is deemed to have consented to give a breath or blood sample that can be used to determine their blood alcohol content (BAC).
It is important to note that implied consent applies to blood alcohol tests taken after a person is arrested, and not to any roadside tests that a police officer may ask a person to take. In many cases, an officer will ask a driver to blow into a portable breathalyzer to determine whether they are over the legal blood alcohol limit. These devices can provide an estimate of a driver’s BAC, but they are not sensitive enough to give an accurate reading, and their results cannot be used as evidence in a criminal case. Instead, they are used to determine whether an officer can reasonably suspect that a driver has violated the law, and they may provide an officer with probable cause to make an arrest. Drivers are allowed to refuse these tests, as well as any field sobriety tests requested by an officer, with no legal consequences, although that refusal may provide an officer with reasonable suspicion that the driver has been drinking alcohol, and the officer may perform an arrest.
