Short description: Vehicle meeting acceptable standards for safe driving


Roadworthiness[1] or streetworthiness is a property or ability of a car, bus, truck or any kind of automobile to be in a suitable operating condition or meeting acceptable standards for safe driving and transport of people, baggage or cargo in roads or streets, being therefore street-legal.

In Europe, roadworthy inspection is regulated by:

  • Directive 2014/45/EU, on periodic roadworthiness tests for motor vehicles and their trailers,[2]
  • Directive 2014/46/EU, on the registration documents for vehicles,[3]
  • Directive 2014/47/EU, on the technical roadside inspection of the roadworthiness of commercial vehicles.[4][5]

Certificate

A Certificate of Roadworthiness (also known as a ‘roadworthy’ or ‘RWC’) attests that a vehicle is safe enough to be used on public roads. A roadworthy is required in the selling of a vehicle in some countries. It may also be required when the vehicle is re-registered, and to clear some problematic notices.[6]

"roadworthiness certificate" means a road-worthiness test report issued by the competent authority or a testing centre containing the result of the road-worthiness test
— DIRECTIVE 2014/45/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 3 April 2014 on periodic roadworthiness tests for motor vehicles and their trailers and repealing Directive 2009/40/EC
