On August 5, 2009 the Bicycle Safety Act went into effect in Colorado. This act helps to clarify several areas of the law relating to bicyclist’s and motorist’s responsibilities on our roads.

The first section addresses a safe passing distance. Motorists need to allow at least three feet of space when passing a bicyclist. – This section also allows a motorist to cross the centerline to make sure that the three feet can be achieved. It’s safest for motorists to wait to cross the centerline if there is oncoming traffic. It is also safer for motorists not to pass heading into a blind curve where oncoming traffic cannot be seen.

The second major provision of the law allows bicyclists to ride side-by-side. These cyclists are required to move to single file when they are aware that a vehicle is approaching and may pass. Motorists should recognize that it takes a few seconds for cyclists to hear them coming and organize themselves into a single file line. So, please be patient, tap on the break if necessary, and give them a chance to single up.

The third area addresses lane positioning. Bicyclists are permitted to ride as far right as is safe. This means that bicyclists can determine how far right is safe so that they don’t ride too close to parked cars, road debris, potholes, and other hazards. Normally, riding in the right half of the lane is generally appropriate for both safety and visibility.

The final point of clarification comes in regard to cycling on one-way streets. Cyclists may ride on the far left or far right on a one-way street. This makes sense for cyclists who are turning left and don’t want to cross several lanes of traffic before their turn (a dangerous maneuver for sure).

The act also makes it illegal for motorists to swerve at (buzz) or throw things at cyclists. – Can you believe we actually need to point this out?

Remember, autos and bicycles must share the road. Especially when you’re in a hurry, don’t do anything that could harm someone else. It’s not worth it!
