What happens if you refuse a breathalyzer in Colorado?

Refusing a breath or blood test after a lawful DUI arrest triggers an automatic license revocation under Colorado’s express consent law, typically longer than the revocation you’d face for testing and failing: 1 year for a first refusal, 2 years for a second, and 3 years for a third or subsequent refusal, with early reinstatement generally available after 2 months. It can also trigger a persistent drunk driver designation and additional mandatory programs, and prosecutors are allowed to tell a jury you refused and argue it shows consciousness of guilt.
