Excerpt from: preventing backovers in america's driveways national highway transportation safety administration 1 vehicle backover injuries and deaths occur when someone, without a driver’s knowledge or awareness, is positioned behind a vehicle as the driver is backing out of a driveway or other parking spot. most victims of backovers are the elderly and children. 2 to add to the tragedy of backover injuries and deaths, the driver is often a neighbor or relative. when a child is the victim, the driver may even be the child’s mother or father. 3 since most of these heartbreaking incidents occur in private driveways rather than on the road, they are not typically included in traffic-crash fatality data. therefore, experts often don’t agree on the exact number of children injured or killed in backover incidents each year. 4 but even one child who dies from a backover incident is one too many. awareness and understanding of the problem are the first steps toward reducing the risk of backover deaths. based on the passage, you can infer that these accidents are particularly devastating because a) victims are often adults. b) the driver is often a relative. c) there are usually no witnesses. d) they happen on private property.
