In Colorado, seatbelt laws are enforced primarily through secondary enforcement, meaning a driver can only be ticketed for not wearing a seatbelt if pulled over for another violation, except when a child is unbuckled, which allows for a primary stop. Surrounding states vary in enforcement: Utah, New Mexico, Oklahoma, and Kansas have primary enforcement allowing stops solely for seatbelt violations, while Wyoming, Nebraska, and Arizona do not permit stops just for seatbelt non-use. Notably, New Hampshire is the only state with no adult seatbelt enforcement but does enforce it for minors.

Additionally, Colorado has introduced 12 new gun laws in 2025 aimed at tightening regulations on firearm ownership and use. Key measures include raising the minimum age to purchase ammunition to 21 starting in 2026, banning rapid-fire conversion devices, requiring background checks and firearm certification courses for certain gun purchases, mandating security plans for gun shows, and expanding felony prohibitions on gun ownership. These laws also address voter intimidation with firearms, improve responses to mass shootings, and create notification systems for protection order holders regarding gun purchases by protected individuals.
