- The HI-pass system allows drivers to pay highway tolls without having to stop and hand over cash.
Hi-pass requires both an Onboard Unit (OBU) and a Hi-pass card.
You can charge the car with amounts ranging from W10,000 to W480,000. There is a W5,000 deposit when your first purchase the card, which can be topped up at any bank.
The discount drivers get from using Hi-pass varies from 5% to 50% depending on the time of day and the specific highway. There is a section on the hi-pass website where you can calculate what your discount will be by inputting, in Korean, the road information and the time of day/night when you will be travelling on it.
