Colorado Governor Jared Polis on Thursday signed a bill into law that establishes a new protocol for crash investigations.

Under the law, police officers are required to offer a voluntary breathalyzer test after every crash involving a death or serious bodily. The law is known as Magnus’ Law, named after Magnus White, a champion cyclist killed near Boulder in 2023. He was 17.

Polis signed the bill into law at Valmont Bike Park in Boulder, one of White’s favorite places, according to a news release from the White Line, an organization that advocates for road safety laws.

Prior to the signing of the bill, there was no statewide protocol to offer a breath test following a crash. Now, there is a clear and consistent process to help investigators gather evidence quickly.

The woman convicted of hitting and killing White was driving while sleep deprived when the accident occurred around noon on July 29, 2023. She was sentenced to four years in prison after a jury convicted her of vehicular homicide.

White’s parents had previously advocated for changes to the law in the wake of their son’s death. Their resilience has paid off, and in a quick way, as the bill was quickly moved through the legislature. According to the release from the White Line, the bill was introduced in March and received overwhelming bipartisan support.
