No. Norway prohibits excessive noise from vehicle exhausts under the Road Traffic Act and Pollution Control Act, enforced by the Norwegian Public Roads Administration and local police. Modified exhausts emitting over 93 dB(A) in stationary tests face fines or confiscation, with stricter urban zones (e.g., Oslo, Bergen) enforcing 85 dB(A) limits. From 2026, digital noise monitoring systems will enhance enforcement, targeting aftermarket modifications.
Key Regulations for Loud Exhausts in Norway
- Decibel Limits: Stationary tests cap exhaust noise at 93 dB(A) nationally; Oslo and Bergen enforce 85 dB(A) in urban areas. Vehicles exceeding limits are deemed non-compliant.
- Type Approval: Aftermarket exhausts must hold ECE Regulation 59.02 certification or equivalent. Unapproved systems are illegal, regardless of noise output.
- Enforcement Actions: Police may issue immediate fines (NOK 5,000–10,000) or confiscate exhausts. From 2026, AI-driven noise sensors will trigger automated penalties.
Non-compliance risks vehicle impoundment, fines, or criminal charges under Section 39 of the Pollution Control Act. Local municipalities (e.g., Trondheim, Stavanger) conduct periodic crackdowns, prioritizing residential zones. Foreign-registered vehicles are subject to identical standards upon entry.
