The word is out that the Colorado Supreme Court recently heard arguments for appealing the state's DUI implied consent laws, based on a trio of appeals of lower court rulings. According to an article published in the Denver Post, the Colorado Supreme Court Justices ruled against the appellants' arguments in each case, thereby effectively upholding the laws as they are now written.
Essentially, the expressed consent law means that every driver who gets behind the wheel in Colorado is subject to breath and blood alcohol tests if a law enforcement officer has probable cause to believe that they are operating the vehicle under the influence of drugs or alcohol. It's a strict law based on the premise that driving is a privilege in Colorado, not a legal right.
Proponents for implied consent laws argue that the law has significantly reduced the number of drunken driving accidents that result in injuries and fatalities throughout the state. Law enforcement agencies across the country are breathing a sigh of relief that the Colorado high court ruled in favor to uphold. If the judges had decided to weaken the DUI laws in this case, it likely could have set a precedent for other states to challenge their own implied consent laws.
