The issue of failing to maintain one’s lane of travel is a common factor in fatal motorcycle crashes in the Commonwealth. In 53 of the 79 (68.3%) fatal motorcycle crashes that occurred in 2008, the motorcycle driver failed to stay in his lane of travel (VMCIT analysis of FR300 reports for fatal motorcycle crashes in 2008). This usually resulted in the motorcyclist running off the road, often then striking fixed objects. In five cases, the motorcyclist crossed the centerline and struck another vehicle head on...
