Riding Against Traffic
Many bicycle accidents happen when the cyclist is riding against traffic. The first thing that bike riders need to realize is that in most states, a bicycle is considered a vehicle, therefore if you are riding your bike against traffic, you are breaking the law. Secondly, it's extremely dangerous for several reasons. When riding against traffic, you leave little time to maneuver away should a vehicle veer in your direction. It's also very dangerous should there be other cyclists riding with traffic in your direction.
Liability
If an accident is caused due to the cyclist riding against traffic, in almost all cases, the rider will be held liable for damages and injuries, just as a car owner driving the wrong way down the road would.
