Samenvatting
A not inconsiderable share of accidents is partly caused or worsened by vehicle faults. These faults- the collapse of parts - occur when it is not recognized in time that parts are not functioning as they should do. Faults can among others be remedied by design measures, such as safety margins and double or separate systems; or in the phase of use, like preventive maintenance, periodical inspection and fault-indication in or at the vehicle. It will be shown that it is important to look at maintenance habits of motorists and that fault indication can offer a good solution in prevention defect accidents.
