Earlier in June, after months of fighting for change, surrounded by supporters, cyclists and lawmakers, Gov. Jared Polis signed "Magnus' Law" — SB26-132 - Voluntary Alcohol Breath Test. "This is now officially the law of Colorado," Polis said at the bill signing. The law requires officers investigating crashes involving death or suspected serious bodily injury to offer drivers a voluntary preliminary breath test. Drivers still retain the right to refuse.
