In 2014 the National Highway Traffic Safety Administration (NHTSA) issued a rule requiring rear visibility technology in all new passenger vehicles by May 2018 to significantly reduce the risk of fatalities and serious injuries caused by backover crashes. While research has shown that rearview video systems (RVSs), when used appropriately, can reduce crash risk, a number of drivers with RVSs report that they ignore them and instead rely on mirrors to avoid obstacles when backing. Previous research by NHTSA and others has found that training can improve drivers' ability to use the systems effectively. Older adults in particular may benefit from this type of training because they are likely to be less comfortable with technology and therefore have more difficulty learning to use these systems than younger adults. In addition, older drivers, particularly ones with age-related stiffness in the spine, may gain the benefit of fewer pedal misapplications if they learn to use the systems effectively. Using an RVS and mirror to check behind the vehicle, instead of turning to the right to check before backing, could help the driver retain his or her position in the seat and thereby reduce the risk of pedal errors. The objective of this study is to assess driving performance of older adults using inside and outside rearview mirrors compared to using an RVS while operating a motor vehicle in reverse. After documenting participants' performance, the project will develop and evaluate an RVS training protocol that addresses the errors identified during the performance period. |
