Summary

Denton's vulnerable road user ordinance tells cyclists where to ride on the roadway and requires drivers to give bikes at least 3 feet of passing room, more for trucks.

(d)(1) A person operating a bicycle on a roadway who is moving slower than the other traffic shall ride as near as practicable to the right curb or edge of the roadway, unless... d. The person is operating a bicycle in an outside lane that is: 1. Less than fourteen (14) feet in width and does not have a designated bicycle lane adjacent to that lane; or 2. Too narrow for a bicycle and a motor vehicle to safely travel side by side. (3) Persons operating bicycles on a roadway may ride two (2) abreast.

Full Breakdown

City Code Sec. 18-36 requires cyclists moving slower than traffic to ride near the right curb, but lets them take the outside lane when it's under 14 feet wide with no adjacent bike lane, or too narrow to share safely with a car. Riders may go two abreast in a single lane without blocking traffic flow. Drivers passing a cyclist must move over a full lane if one is available, or leave at least 3 feet (6 feet for trucks and commercial vehicles) and may not cut back in front of the rider.

Violations & Fines

Traffic offense; Sec. 1-12 caps fines for traffic-related violations at $200 per offense, with each day of a continuing violation a separate offense.
