Learn more about chemical sobriety tests 

On Behalf of | Jun 20, 2024 | Criminal Defense |

One of the ways the police will gather evidence during a traffic stop is by having drivers take chemical sobriety tests. 

If you are asked to take a chemical sobriety test, it can help you to learn more about what is being asked of you. Here is what you should know:

What do chemical sobriety tests do? 

A chemical sobriety test evaluates the blood alcohol content (BAC) in your body. Your BAC reading will be higher with the more alcohol you drink. If your BAC exceeds the legal driving limit of 0.08% or higher in North Carolina, then you could be arrested and charged with drunk driving. 

What are the different types of chemical tests?

There are three types of chemical tests. The most common and convenient is a breath test, which reads your BAC by blowing into a machine. Alternatively, you could have your blood or urine tested. 

How accurate are sobriety tests?

While chemical sobriety tests can be accurate, that does not mean they are always right. For example, lab errors could cause urine and blood tests to read incorrectly. Breath tests may report a higher BAC if the driver had a breath mint before being administered the test. 

Can you refuse sobriety tests? 

Unless there is a warrant for the test, you may have the right to refuse. Yet, under implied consent laws, you may face steep penalties for refusing a post-arrest sobriety test.

You can reach out for legal help to discuss the matters of a traffic stop and a drunk driving case. Doing so could help you strategize a defense against serious criminal charges.
