IRVINE, Calif., May 6, 2010 - Half of all motorcycle crashes involve a collision with another vehicle and the car driver is most often at fault. The Motorcycle Safety Foundation urges all drivers to give riders some space and to not "be that guy" that hits a motorcyclist. Killing or injuring a rider is something that you would have to live with for the rest of your life, and nobody needs that guilt. Remember, drive nice, look twice and see the riders.
