A large percentage of the motorcycle accidents in Louisiana happen because of the small size of the bikes. Since they are so much smaller than cars and other vehicles, the drivers of those vehicles will often not notice where they are on the road -- even though bikers have as much of a right to use the road as anyone else.
This can lead to many types of accidents. In some cases, cars will turn left, as if the road is clear, cutting across the path of a bike that is coming the other direction. In other cases, drivers will merge into the same lane as a motorcycle that is traveling in the same direction that they are. Furthermore, some accidents happen at stoplights when cars and trucks do not stop quickly enough, running into the backs of bikes that are already at a standstill.
