  • (b) 5.6 tonnes for Class 6 and Class 7 vocational vehicles and incomplete vocational vehicles,

  • (c) 7.5 tonnes for Class 8 vocational vehicles and incomplete vocational vehicles,

  • (d) 12.5 tonnes for Class 7 tractors and incomplete tractors, and

  • (e) 19 tonnes for Class 8 tractors and incomplete tractors;

  C

  is the number of vehicles in the fleet or subfleet, as the case may be; and

  D

  is the useful life for the class of vehicles, as follows:

  • (a) 110,000 miles for Class 2B, Class 3, Class 4 and Class 5,

  • (b) 185,000 miles for Class 6 and Class 7, and
