The in-vehicle information systems (IVIS) aim to help the driver by providing information, for example, about routes, traffic congestion and accidents. Because these systems can provide drivers with real-time information there is a growing concern that they may interfere with the primary driving task and thus compromise safety.

Similarly, the possibility of providing drivers with an in-vehicle office environment (with telephone, fax machine, e-mail and computer) raises serious safety concerns - as do some advanced entertainment systems. While these systems should come with 'advice' about not using them while driving (as is currently the case with mobile phones) the driver may be tempted to ignore such advice. In addition to the distraction issue, there are also potential safety problems with respect to the driver being given incorrect information by the IVIS. It is thus essential that drivers be reminded about their responsibilities regardless of information provided by these systems.
