Getting into a car accident is terrible and can lead to a serious injury, but if you're riding a bicycle and crash, the chances of suffering a major, life-threatening injury increases exponentially. It's an inherent risk of being a cyclist. You're body is exposed to the elements and the full onslaught of damage if struck by a vehicle, or if you slam into an object like a tree or guardrail.
Even with increased awareness to bicycle safety, 716 cyclists were killed in traffic accidents back in 2008. In addition, 52,000 cyclists were injured in accidents in 2008, a 21 percent increase.
