If you are pulled over under suspicion of drunk driving, you will be asked to undergo DUI testing. A breathalyzer or blood test serves as incriminating evidence against you. Know your rights when it comes to requests to undergo these examinations. Here’s what drivers in Missouri need to know.

FAQ About DUI Testing

What warrants a request for a DUI test?

The police who pulled you over must have evidence of intoxication. This could include your behavior, such as not driving in a straight line, as well as statements you made. Saying something like "I just had three beers" is technically an admission of guilt.

How is DUI testing done?

The officers will first ask you to conduct field sobriety tests, including tasks like touching your finger to your nose with your eyes closed. If they have probable cause to suspect intoxication, they will then request an on-site portable breath test. When breathalyzer results are over 0.08, they will take you into custody and ask for a blood test; these results are harder to dispute in court.

What if you refuse to take a test?

Like many states, Missouri has an implied consent law. If you refuse to take a breath test, you are thus subject to a one-year license revocation. You may be able to get a limited driving privilege license during this period of time; this allows you to only get behind the wheel for certain approved reasons, like getting to work.

Can you beat DWI charges? 

A skilled DUI attorney can offer many possible defenses depending on your situation. If you didn’t take the breath or blood test, for instance, the case basically comes down to your word versus the police officer's. Your lawyer could argue that the police actually didn't have reasonable cause to stop you and request a test.
