How to use transit adjustment

ETC customers

Customers using ETC should use wireless communication to drive through the designated exit IC and also to drive through the designated re-enter IC. (ETC vehicles will not be issued a "transfer certificate.")
The connected journey will be treated as a single journey and the ETC time-of-day discount will be applied.
Please note that tolls are adjusted at the time of billing, so they may differ from the toll displayed on the toll booth.
Please insert the same ETC card for the entire journey and pass through the ETC lane at the toll gate.

Customers such as cash

Customers paying with cash, etc. should receive a "transfer certificate" at the outflow designated IC, then take a "transit ticket" at the re-inflow IC, and then take the "transition certificate" at the toll booth where they pay the toll for the first time. Please hand over your ``book'' and ``traffic ticket.''

Common to ETC and cash customers

If the suspension of traffic is released after the outflow designated IC is released, the fare will be adjusted even if it is re-introduced from the IC (including the outflow designated IC) in the closed road section in the forward direction.
