Tolls are paid for some bridges, tunnels and highways in Abu Dhabi and Dubai. Tolls are collected through a system that senses the passage of vehicles through toll gates and the 4 AED transit fee is subsequently charged from the prepaid account registered to the vehicle. In Abu Dhabi, the vehicle registration plate is used to identify the vehicle at the toll gate, in Dubai a chip sticker must be put on the windshield of the vehicle. The location of the Toll Gates is indicated on the map above.
