Wear a helmet.
Minors (persons under 18 years of age) are required to wear a bicycle helment. Helmets are just a good idea.
Ride in the street, not on the sidewalks.
Riding on sidewalks is allowed outside of the central business district, but not encouraged.
Ride with traffic, not against it.
Stop at red lights and stop signs.
Obey all traffic signals, signs and pavement markings.
Use marked bike lanes or paths when available, except when making turns or when it is unsafe to do so.
If the road is too narrow for a bicycle and a car to travel safely side by side, you have the right to ride in the middle of the travel lane. Bicycling is permitted on all main and local streets throughout the City, even when no designated route exists.
Ride in a straight line, obey traffic signs and signals, and do not weave in and out of traffic.
Riding predictably reduces your chances of a crash with a motor vehicle.
Look, signal, and look again before changing lanes or making a turn.
Establish eye contact with drivers. Seeing a driver is often not enough. Make sure drivers see you before executing a turn or riding in front of a turning car.
Watch out for car doors.
Be prepared for the possibility that a car door may be opened in your path. When possible, leave room between yourself and parked cars (3 feet is generally recommended) so that you can avoid a door that opens unexpectedly.
Wear brightly colored clothing for daytime riding. At night, use reflective materials and lights.
Use a bell.
A bell alerts drivers, pedestrians and other cyclists to your presence.
Don't wear earphones while riding.
Keeping your ears clear is a much safer choice.
