What happens if a vehicle has been modified after passing inspection?

When a vehicle has been modified after it has passed inspection, it may require re-inspection if those modifications impact safety or emissions. This is crucial because the primary purpose of vehicle inspections is to ensure that vehicles meet safety standards and comply with environmental regulations. Modifications such as changes to the exhaust system, suspension, or braking components can alter the vehicle's performance and safety profile. Therefore, if such modifications are made after the initial inspection, they could lead to potential hazards or non-compliance with emissions requirements, prompting the need for a follow-up inspection to ensure the vehicle is still safe and roadworthy.

The focus on safety and emissions underscores the importance of maintaining strict standards, which is why re-inspection is necessary when modifications could influence these critical aspects.
