Johannesburg - The e-tolls bill, signed into law on September 25, could see daily car hire rates hiked by an estimated 10%.Travelbuyer.co.za reports the president of the South African Vehicle Rental and Leasing Agency (Savrala), Marc Corcoran expects the yet to be decided tarrifs to affect both international and domestic customers renting cars in South Africa. Gauteng Tourism spokesperson, Barba Gaoganediwe, says the e-tolls will work like any other toll gate or traffic fine and that tourists renting cars should simply be billed for these fees by the rental companies.Corcoran explains that there are still major industry concerns, however, including that Savrala members are expected to pay for e-toll transactions within 48 hours, even though a renter may only pay the car rental company much later. Following are the proposed toll tariffs per kilometre according to the Government Gazette - these have been open for public comment for a period of 30 days until 8 November.Class A1 (motorcycles): 35c/km standard, 18c/km e-TaggedClass A2 (light vehicles): 58c/km standard, 30c/km e-TaggedClass B (medium heavy): 145c/km standard, 75c/km e-TaggedClass C (large heavy): 290c/km standard, 150c/km e-TaggedDawn Nathan-Jones, CEO of Europcar said,"We have made a considerable investment in time, funds and resources to contain the costs to customers.""To achieve this and to pass on tagged rates, Europcar has created integrated systems with SANRAL and tagged its entire fleet, not just Gauteng-based vehicles, to reflect customer travel patterns.""Europcar will bill their customers the gazetted fee per toll gantry passed plus an administration fee per gantry. These fees will be included on the customer’s rental invoice to avoid multiple invoices per transaction, " Said Nathan-Jones.Due to the SANRAL processing and a required transaction validation period, customers could expect billing to be delayed by an additional 24 hours.Europcar said this solution applies only to the Gauteng Open Road Tolling (GORT) system and customers would continue to pay at Bakwena and other interoperable tolling stations throughout the country.Car-rental customers could also expect an increase in deposit requirements to cater for e-toll charges on leisure and international customers.
