Longmont's Mobility & Curb Rules: The Rules That Matter
Every city handles mobility & curb rules a little differently. In Longmont, Colorado, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Bike Lane Rules
Longmont's traffic code bars drivers from stopping, standing, or parking in any area marked with a bicycle lane, one of a list of specific places where stopping is prohibited citywide.
Key details: Prohibited act: Stop, stand, or park in bike lane. Governing rule: Model Traffic Code § 1204(1)(m). Case type: Civil traffic infraction. Exception: Police direction or traffic control device.
Stopping, standing, or parking in a striped bicycle lane is a civil traffic infraction under LMC § 11.06.020, fined per the schedule in § 11.04.140.
Red-Light Cameras
Longmont runs an automated vehicle identification system that photo-cites red-light-signal violations and speeding in school zones, residential streets, and 13 named corridors.
Key details: Signal violation penalty: Up to $75. Speeding penalty: $40, or $80 in school zone. Adopted: Ord. O-2024-77, Nov. 2024. Corridors: 13 named streets, per § 11.05.050.
A camera-detected signal violation carries up to a $75 civil penalty under § 11.05.040; camera-detected speeding carries up to $40 ($80 in school or work zones) under § 11.05.030: both are civil, not criminal, and owners may contest by written hearing request within 46 days.
E-Bike Classes
Longmont's traffic code defines electric-assisted bicycles by three classes based on motor assistance and top assisted speed, tracking Colorado's statewide e-bike classification.
Key details: Motor cap: 750 watts. Class 1 / 2 top speed: 20 mph assisted. Class 3 top speed: 28 mph assisted. Class 2 distinction: Throttle without pedaling.
There is no separate class-specific penalty; violations of the general bicycle operating rules in LMC § 11.04.113 apply equally across all three e-bike classes.
If you are coming from a city with tighter rules, you will find Longmont gives residents more flexibility on e-bike classes.
The Bottom Line
Longmont's mobility & curb rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Longmont is broadly strict or permissive.
