New Brunswick RCMP have released updated guidelines on vehicle modifications that pass provincial road safety inspections. The clarification aims to help drivers understand which alterations are legal and safe for public roads.
Key Modification Rules
According to the RCMP, modifications affecting lights, tires, suspension lifts, and exhaust systems must meet specific standards. Headlights and taillights must be properly aimed and functional, with no unauthorized colored bulbs. Tire modifications must not exceed manufacturer-recommended sizes without proper certification.
Suspension and Lift Kits
Lift kits are allowed but must not raise the vehicle beyond safe handling limits. The RCMP emphasizes that any modification altering the vehicle's center of gravity requires a professional inspection to ensure stability.
Exhaust Systems
Aftermarket exhausts must comply with noise regulations. Excessively loud systems or those that remove catalytic converters are prohibited. Drivers should check local bylaws for additional restrictions.
Inspection Process
Vehicle owners must present their modified vehicles at an authorized inspection station. The RCMP recommends consulting a certified mechanic before making changes to avoid costly adjustments later. Failing modifications can result in fines or vehicle impoundment.
