ROUNDABOUTS
Although popular in Europe for many
years, roundabouts are relatively new to
Colorado. A roundabout is designed to
slow traffic and reduce hazards common
to four-way intersections.
Rules for navigating
roundabouts:
• Vehicles entering the circle yield
the right-of-way to traffic already
in the circle.
• Traffic proceeds in a
counterclockwise direction around
the circle, even when making a left
turn at the intersection.
• All vehicles yield to pedestrians in
crosswalks.
• When approaching the roundabout,
bicyclists should merge to the
center of the lane (take the lane).
• Motor vehicles should follow
bicyclists through the circle.
• Motor vehicles should not speed up
to pass bicyclists.

RIDING ON SIDEWALKS & IN CROSSWALKS
You are allowed to ride your bicycle on a sidewalk or in a crosswalk unless it is prohibit-
ed by official traffic control devices or local ordinances. When riding on a sidewalk or in
a crosswalk, you must observe all the rules and regulations applicable to pedestrians,
yield the right-of-way to pedestrians, and give an audible signal before passing them. An
audible signal can be a bell, horn or your voice saying, “Hello, passing on your left.”
However, riding on sidewalks is not recommended. Many crashes between bikes and
cars occur on sidewalks at driveways and street crossings, especially when bicyclists
ride against the flow of traffic. You should always walk your bicycle in busy shopping
areas or on downtown sidewalks. Sidewalks are for pedestrians, not bicyclists, and you
should be courteous and ride slowly and cautiously.
