Bicycles are vehicles too.
Some bicyclists ignore the rules.
That doesn't mean you should imitate their behavior. Most crashes involving bicyclists and motorists occur at intersections. This often happens when a motorist pulls out from a stop sign or driveway without yielding, or turns across the bicyclist's path. When turning right, slow and merge behind a bicyclist ahead of you to make your turn from the right edge of the road. When turning left, yield to on- coming bicyclists, even those at the far side of the road.
