A person who, being in charge of a vehicle on a road, allows such quantity of mud, clay, farmyard manure, or other material (of whatever nature) from the vehicle, or from anything carried on the vehicle, to drop onto or be deposited on the road so as to create, or be likely to create, a danger or substantial inconvenience to road users and who fails to remove the material as soon as reasonably practicable commits an offence.

Expenses reasonably incurred by the roads authority F1. . . and necessitated by a contravention of this section may be recovered by them from the person in default.

In this section any reference to a person in charge of a vehicle shall be construed as a reference to a person who as owner or otherwise has the immediate charge or control of the vehicle or who being present is entitled to give orders to the person having such charge or control.

In this section, “vehicle” includes anything towed or pushed by a vehicle, and any appliance.

Subject to subsection (3) below, where as respects any public road it appears to the roads authority (where they are a local roads authority from a certificate of the proper officer of the authority) that having regard to the average expense of maintaining the road, or other similar roads in their area, extraordinary expenses have been, or will be, incurred by them in maintaining the road by reason of damage caused to it by excessively heavy, or other extraordinary, vehicles or traffic, they may recover from any person (in this section referred to as the “operator”) by or in consequence of whose orders the vehicles have, or traffic has, been on the road, so much of the expenses of maintenance as is, or is likely to be, attributable to that damage.

In subsection (1) above the expenses incurred by a roads authority in maintaining a road are (without prejudice to the application of this section to a by-pass provided under this Act for use in connection with a cattle-grid) to be taken to include expenses incurred by them in maintaining a cattle-grid provided for the road under this Act.

If, before operations which may cause such damage commence, the operator admits liability in respect of the vehicles or traffic, he and the authority may agree the payment by him to them of a sum by way of a composition of such liability, or either party may require that a sum to be so paid shall be determined by arbitration; and where a sum has been so agreed or determined the operator shall be liable to pay that sum to the roads authority and shall not be liable to proceedings for such recovery as is mentioned in subsection (1) above.

Subject to subsection (5) below, sums recoverable under this section shall be recoverable before the sheriff.

Such proceedings as are provided for in subsection (4) above shall not be commenced later than 12 months after the damage has been done unless that damage is the consequence of a particular building contract or of work extending over a long period, in which case they may, notwithstanding that such period of 12 months has elapsed, be commenced within six months of completion of the contract or work.
