Dangerous roads and intersections are not generally considered in a bicycle accident but they are a leading factor in bicycle accidents. A dangerous road condition can involve, but is not limited to: Potholes and street deterioration, Bike lanes placed adjacent to parked cars, Lack of bicycle lanes, Construction zones that obstructs the bike lane, Drastic downhill incline, and overgrown weeds and brush.
According to the Journal of Public Health, when bike lanes have been placed on the road, the risk of cyclist injury can decrease by 50 percent. When a city constructs protected bike lanes, the risk of injury is reduced by 90 percent.
As previously mentioned, driver negligence is the top contributing factor of bicycle accidents. When a driver is speeding, is distracted, or is driving under the influence, he or she can strike a cyclist causing him or her catastrophic injuries. Other negligent actions can include: Driving while sleep deprived or fatigued, Aggressive driving, Failing to properly signal before changing lanes, Changing lanes excessively, Failing to yield, and/or Failing to follow posted street signs.
When a cyclist is traveling down a bike lane that runs adjacent to parked cars, he or she runs the risk of suffering a dooring accident. A dooring accident can occur when the driver of a vehicle exits his or her car without first checking for an oncoming cyclist. When a rider collides with the suddenly opened door, he or she can suffer serious head injuries, including facial disfigurement. In other cases, the rider can be placed in even greater danger when he or she instinctively drives into the oncoming traffic in an attempt to avoid colliding with the suddenly opened car door.
