Motorcyclists face a number of risk factors that do not affect car drivers. The main risk factors are decreased stability and a much lower level of occupant protection than is provided by a car. In addition, a motorcycle is less visible to other road users than a car or a truck. These factors together give motorcycling a higher level of risk per kilometre travelled than other modes of transport.
