Regulation 5 Place and manner of payment
Except where paragraph (2) applies, all tolls leviable in respect of a vehicle, shall be paid by the driver of the vehicle, in cash to an appointed person at a toll-booth, or by the insertion of coins into a machine provided near a toll-booth for the purpose of collecting tolls, not being in either case a toll-booth at which a sign is displayed indicating that its use is restricted to either—
vehicles of a class which does not include the relevant vehicle, or
vehicles for which the toll leviable has been paid in advance.
Where, pursuant to a pre-payment agreement, the toll leviable for a vehicle has been paid in advance, the driver shall present or display such evidence of payment in such manner and at such place within the existing toll plaza area as the agreement may provide.
Every driver of a vehicle, proceeding westbound in the existing toll plaza area, shall stop the vehicle in a position where he can, in accordance with this regulation, pay any toll leviable for the vehicle or present or display evidence of payment of the toll without leaving the vehicle or, if the toll has been paid in advance and the pre-payment agreement so provides, he shall slow down the vehicle sufficiently to enable the evidence of payment to be verified.
When a red light is displayed at a toll-booth, the driver of a vehicle proceeding westbound in the existing toll plaza area in the traffic lane alongside that toll-booth shall not allow the vehicle to proceed beyond the toll-booth, until a green light is displayed or a constable in uniform or an appointed person allows or directs him to proceed.
