A TAC permit is required for tridem axles or loads exceeding a GVW of 53,500 kg.  This permit allows tridem axles and/or vehicle configurations with a GVW greater than 53,500 kg to operate on local roads at the same legal maximum weights as on Provincial Highways as per Alberta Regulation 315/2002.  A tridem axle is restricted to 17,000 kg on any municipal roadway unless a TAC Permit is acquired.

The TAC permit can be obtained through RoaData Services.
