We can evaluate your case, determine your legal options, and find any weaknesses in the prosecution’s case to protect your rights, reputation, and freedom.

DUI Breath Test vs. Preliminary Breath Test

As a licensed driver in Colorado, you automatically provide consent to a chemical test if you are lawfully arrested for driving under the influence. This is known as the state’s “express consent” law.

That means if you refuse a post-arrest breath test, you will lose your driver’s license for one year. If you refuse a second time, you lose your license for two years. For your third or any subsequent refusal, it results in a three-year license suspension.

On the other hand, when a person is pulled over for a traffic violation or suspected of DUI, a police officer may ask him/her to take a roadside preliminary breath test (PBT). If you at least 21 years of age, you may decline this type of breath test without facing legal consequences. Similar to all field sobriety tests, it’s a tool that helps law enforcement establish probable cause for arrest.

Ready to Challenge the Results of the Breath Test Today!

There is a wide range of legal defenses that can challenge the results of the chemical test. In many cases, law enforcement failed to properly administer the test, leading to discrepancies in the results. Additionally, it is possible that the testing device wasn’t adequately calibrated.
