Recent research indicates that driver error contributes to most accidents. Despite this, only relatively little is currently known about the types of errors that drivers make and of the causal factors that contribute to these errors being made. This paper presents an overview of the literature on driver error in road transport. A generic driver error classification scheme is proposed based upon the dominant psychological mechanisms thought to be involved. A range of potential technological solutions that could be used to either prevent, or mitigate, the consequences of the driver errors identified are specified
