Share the road. Don't assume motorists can see you.
Ride on the right, but not too close to parked cars. Drivers might open a car door without seeing you.
Never ride against traffic. Follow signs, signals and pavement markings.
When turning left, merge with left-turning traffic or walk your bike across as a pedestrian if traffic is heavy.
Inform others of turns by using hand signals. These are the same as motorists' hand signals except that for turning right you can use your right arm and point.
Slow down and yield for pedestrians.
Be predictable. Avoid sudden swerves.
Common sense, courtesy, and caution are the three C's of good cycling.
Watch the road. The American Automobile Association suggests using an accident avoidance technique called "SIPDA": scan, identify, predict, decide, and then act.
