The National Heavy Vehicle Accreditation Scheme (NHVAS) has been developed to offer transport operators a voluntary alternative means to comply with the regulatory requirements for mass limits and vehicle maintenance.
Operators are able to gain accreditation to the NHVAS if they prove they comply with the law through meeting the alternative compliance standards. Accredited operators need to:
Develop an in-house assurance system
Document the procedures staff must follow to achieve compliance
Produce (and keep for audit) sets of documents that prove compliance
Undergo independant audits from time to time.
There are currently 2 modules available under the NHVAS:
Mass Management
Maintenance Management
