As more people are downsizing their vehicles because of high gas prices, motorcycle and bicycle collisions are rising. The San Diego County Bicycle Coalition believes that the amount of bike-commuters has doubled in the past year. The number of motorcycle licenses has also increased in the California from 908,000 in 2002 to over 1 million currently. Consequently, deaths involving motorcycle and bicycle accidents are rising throughout California, as well as the nation. Considering the state of the economy, it is likely that more people will take to the road in motorcycles and bikes, even scooters and mopeds. However, this is not the first time this has happened. Accidents increased several years ago when bikes became more common on the roads because of environmental concerns. In order to reduce the amount of accidents, both cyclists and drivers need to become more aware. Motorists must learn how to share the road properly, and bikers need to follow safety laws, such as observing stop signs. The Motorcycle Safety Foundation offers classes for new motorcyclists that includes 10 hours of driving instruction.
