Analysis of pass/fail rates and accidents for different vehicle types in relation to PTI - frequency and vehicle age. AUTOFORE study on the future options for roadworthiness enforcement in the European Union, workpackage WP 540.

The results of the periodic motor vehicle inspections show that the percentage of vehicles with defects related to road safety increases significantly as the car ages. Older cars were the cause of a far greater proportion of fatal accidents compared with newer cars. The increase in accidents caused by a car as it gets older approximates the age-related increase of the number of faults found in cars during the periodic motor vehicle inspection. The compared failure (and accident) rates between different member states show also approximately the same factors. Therefore it is a adoption to devolve the detailed german cognitions to other member states, because the same expected circumstances. A decision for changed PTI-periodicities for the first or following inspections can’t give this document. But it ist possible to show the most applied succesfully methods because experience in the member states regarding to failure rates, vehicle age and accident causes. Under the point of subsidiarity the member states can follow the proposals or apply own methods in the given frame of 96/96/EC.
