NSM Certification




THE NATIONAL SAFETY MARK (NSM) Canadian trailer manufacturers and truck body and equipment installers are required to have National Safety Marks (NSM's) issued by Transport Canada in manufacturing trailers, installing truck bodies and equipment, and modifying wheelbases and gross vehicle weight ratings (GVWR). Vehicles built in America and shipped to Canada must also have the NSM certification.

Are Surge Brakes Legal In Canada?

An electronic breakaway switch is required on all trailers equipped with brakes. Brakes are required on each axle of a trailer with the exception of three-axle trailers, where brakes are needed only on the first two. On trailers with a gross weight of more than 6160 pounds, surge-type brakes are not acceptable.

World Manufacturer Identifier (WMI)

Vehicle Identification Number

A VIN consists of 17 characters which uniquely identifies a vehicle or trailer. The VIN shall be permanently marked on right side of the vehicle and also appears on the manufacturer’s plate affixed to the vehicle. The characters “I, O and Q” shall not be used anywhere in the VIN as these can be confused with numerical characters.

The 17 characters of the VIN can be divided into 3 sections:

World Manufacturer Identifier (WMI)

A WMI is the first 3 characters of a vehicle Identification Number (VIN) which uniquely identifies the manufacturer of a motor vehicle or trailer. The code is assigned to a vehicle manufacturer in order to allow identification of the said manufacturer and when used in conjunction with the remaining section of the VIN, ensures uniqueness of the VIN for all vehicles manufactured for a period of 30 years.

NSAI is the Irish national organisation responsible for issuing manufacturers with a WMI in accordance with International standard ISO 3780. If the manufacturer produces fewer than 500 vehicles in the year the 3rd character of the WMI will be denoted with the number “9” and the 12th, 13th and 14th characters of the VIN will also be assigned by NSAI.

Vehicle Descriptor Section (VDS)

It provides information describing the general attributes of the vehicle. This shall consist of 6 characters. If the manufacturer does not use one or more of these character spaces the spaces not used shall be filled by alphabetical or numeric characters of the manufacturer’s choice. The coding and sequence of this section are determined by the manufacturer.
