Recovery of damage to road or bridge

(1) If, by reason of an offence against this Act or any regulations, any injury is caused to any road or bridge, the authority responsible for the repair of the road or bridge may cause such injury to be made good, and may, either before or after the injury is made good, recover the estimated or actual cost thereof from the owner of the motor vehicle by the use of which the offence was committed. (2) A certificate under the hand of the Chief Engineer, or any person authorised by him in that behalf, of the amount of the cost of making good the injury mentioned in this section, shall, without proof of signature, be sufficient evidence of the amount payable by the owner of the vehicle unless the contrary is proved.
