Grand Junction, CO Mobility & Curb Rules: Bike Lane Rules (2026)

GJMC § 10.04.714 puts the burden squarely on motorists: the driver of a vehicle shall yield the right-of-way to a bicyclist or other authorized user of a bicycle lane whenever that person is riding in the lane. A driver who fails to yield commits a basic traffic infraction under subsection (2)(a). The penalty steps up sharply once the failure causes harm: subsection (2)(b) reclassifies the violation as careless driving under GJMC § 10.04.1402 if the driver's actions proximately cause a crash, and again if they proximately cause bodily injury to another person, each a misdemeanor rather than a civil traffic infraction.

The rule sits inside Grand Junction's broader set of bicycle-specific traffic rules. GJMC § 10.04.1412 gives bicyclists, electrical-assisted-bicycle riders, and electric-scooter riders the same rights and duties as any other vehicle driver, including the right to occupy a full lane when the available lane is too narrow to share safely, and it lets a rider avoid hazards such as parked cars, debris, or narrow lanes at the edge of the roadway without being cited. Motorists overtaking a cyclist face their own separation duty: GJMC § 10.04.1002(2) bars a driver from passing a bicyclist moving in the same lane when there is oncoming traffic unless the driver can give oncoming vehicles half the roadway and still leave the bicyclist at least three feet of clearance from the car's mirrors or other projections.

Grand Junction Police Department officers write these citations, most often after a same-direction sideswipe or a bike-lane merge conflict, and the Municipal Court applies GJMC § 10.04.1701's traffic-infraction cap of $1,000 unless the careless-driving misdemeanor track under § 10.04.1402 applies instead.
