(1) This section applies to a dimension requirement imposed by reference to the overall width of a vehicle or combination with or without a load.
(2) In the case of a vehicle or combination with a load, a breach of a dimension requirement to which this section applies is categorised by reference to the length of the projection of the load from a side of the vehicle or combination.
(3) If the load projects from both sides and the length of the projection from one side is greater than the length of the projection from the other side, the breach is to be categorised by reference to the longer projection.
(4) Nothing in this section affects a person’s liability for a breach of a dimension requirement to which section 35 (Lower limits-width breaches) applies.
(5) Substantial risk breach The lower limit for a substantial risk breach of a dimension requirement to which this section applies is:(a) in the case of a vehicle or combination with a load projecting from a side of the vehicle or combination, 40 millimetres measured from a side of the vehicle or combination, or(b) in any other case of a vehicle or combination with or without a load, 40 millimetres over the maximum permissible dimension limit.
(6) Severe risk breach The lower limit for a severe risk breach of a dimension requirement to which this section applies is:(a) in the case of a vehicle or combination with a load projecting from a side of the vehicle or combination, 80 millimetres measured from a side of the vehicle or combination, or(b) in any other case of a vehicle or combination with or without a load, 80 millimetres over the maximum permissible dimension limit.
