Signatures submitted for Colorado initiative to spend motor vehicle and fuel tax revenue on roads; legislature passes bill to counter measure, if approved by voters

In Colorado, signatures were submitted to the secretary of state on May 26, 2026, for a ballot initiative related to funding road transportation expenses.

More specifically, the measure — referred to as Initiative 175 — would add a new section to Article X of the Colorado Constitution to require both the state and local governments to spend any state revenue collected to support road transportation on costs related to:

• the construction, maintenance, and operation of public streets, roads, highways, or bridges;
• the development and improvement of safety measures for motor vehicles traveling on public streets, roads, highways, or bridges;
• the design, engineering, and management required for road transportation; and
• the Colorado state patrol.
