type: "Bill"
title: "Bicycle Operation Approaching Intersection"
description: "The bill permits a municipality or county to adopt a local ordinance or resolution regulating the operation of bicycles approaching intersections with stop signs or illuminated red traffic control signals. The ordinance shall not, however, apply to any portion of the state highway system. Under a local regulation, a bicyclist approaching a stop sign must slow to a reasonable speed and, when safe to do so, may proceed through the intersection without stopping. A bicyclist approaching an illuminated red traffic control signal must stop at the intersection and, when safe to do so, may proceed through the intersection. The bill sets the reasonable speed limit at 15 miles per hour. However, a municipality or county may lower the reasonable speed to 10 miles per hour or raise the limit to 20 miles per hour at any individual intersection. If the local government sets a lower or higher reasonable speed limit, the local government must post signage indicating that speed limit at the intersection. If the municipality or county adopts an ordinance or resolution pursuant to the act, it must be consistent with the act. An ordinance adopted before the effective date of the act that similarly regulates bicycles remains valid."

# Colorado SB 18-144 (2018A) — Bicycle Operation Approaching Intersection

The bill permits a municipality or county to adopt a local ordinance or resolution regulating the operation of bicycles approaching intersections with stop signs or illuminated red traffic control signals. The ordinance shall not, however, apply to any portion of the state highway system. Under a local regulation, a bicyclist approaching a stop sign must slow to a reasonable speed and, when safe to do so, may proceed through the intersection without stopping. A bicyclist approaching an illuminated red traffic control signal must stop at the intersection and, when safe to do so, may proceed through the intersection. The bill sets the reasonable speed limit at 15 miles per hour. However, a municipality or county may lower the reasonable speed to 10 miles per hour or raise the limit to 20 miles per hour at any individual intersection. If the local government sets a lower or higher reasonable speed limit, the local government must post signage indicating that speed limit at the intersection. If the municipality or county adopts an ordinance or resolution pursuant to the act, it must be consistent with the act. An ordinance adopted before the effective date of the act that similarly regulates bicycles remains valid.
