	Historically, about one in every three fatal accidents is a result of a single vehicle leaving the roadway and striking a fixed object or overturning. Guardrail and guard cable play a major role in saving lives in vehicle crashes by preventing vehicles from leaving the roadway and striking a hazard. Guardrail and guard cable work by containing the errant vehicle and redirecting the vehicle away from hazards. Guardrail and guard cable can shield fixed objects and steep slopes, can be used in tangent or curved sections of roadway and can be used to shield bridge ends and piers from vehicle impacts.

			Multiple roadway safety studies have shown that guardrail along the edge of the road can reduce the number of crashes and their severity. A 1995 study cited in an ATSSA roadside safety report indicates that the presence of guardrail reduced the overall crash rate by approximately 30%, reduced fatality crashes by 45% and reduced injury crashes by 50 percent. NCHRP Report 490 (2003) presents in-service performance evaluation findings from studies in Connecticut, Iowa and North Carolina that found only a 3% severe injury rate for crashes involving w-beam guardrails.
