Interpretation
	2.	In these Regulations, “the Act” means the Road Transport Charges (Australian Capital Territory) Act 1993.
What are the axle load limits for special purpose vehicles?
	3.	For the purposes of the definitions of “special purpose vehicle (type 1)” and “special purpose vehicle (type 2)” in Part 1 of the Schedule to the Act, the load limit for an axle or axle group specified in column 2 of Part 1 of the Schedule to these Regulations is specified in column 3 of Part 1.
How is N ascertained for the purposes of Part 3 of the Schedule to the Act?
	4.	(1)  For the purposes of the formula set out in Part 3 of the Schedule to the Act, the number N, in relation to a vehicle or a combination of vehicles that includes one or more trailers, is the sum of the equivalent standard axles for each of the rows of tyres across the trailer or trailers.
	(2)	For the purposes of subregulation (1):
	(a)	the number of equivalent standard axles for a row of 8 tyres across a trailer is determined by reference to Table A in Part 2 of the Schedule; and
	(b)	the number of equivalent standard axles for a row of 4 tyres across a trailer is determined by reference to Table B in Part 2 of the Schedule.
	(3)	For the purposes of subregulation (2) and Part 2 of the Schedule, the average load (in tonnes) for a row of tyres across a trailer is worked out using the following formula:

			C
			B

where:
		C is the loaded mass  (in tonnes) of the trailer;
		B is the number of rows of tyres across the trailer.
