An assessment is required following modifications to your vehicle. When must this be performed?

According to German traffic regulations, any significant modification to a vehicle must be assessed promptly after the change. This is to ensure that the vehicle still meets safety and legal standards before it is used on public roads. Waiting until the next scheduled inspection or only when requested by authorities is not sufficient because the modification could affect roadworthiness or compliance immediately. Therefore, the assessment must be done right after the modification to guarantee safety and legality.
