Is it true that just by driving in Colorado a person expressly consents to have their Blood Alcohol Content evaluated?
Yes. The Colorado Express Consent law assumes that if you are driving on the roads of Colorado, you have automatically given consent to have your Blood Alcohol Content evaluated if an officer has reason to believe you have been drinking. This means the DMV has the authority to take away your license if you do not do so. However, at the same time you have the right to refuse the test based on your constitutional right to not incriminate yourself.
