Where to Stick the OBU?

[Adrian]

Typically, the ETC OBU is installed behind the rearview mirror or in the middle position of the windshield. Here is relevant information: 1. The Electronic Toll Collection System (ETC) is a fully automatic toll collection system that enables vehicles to pay highway tolls without stopping by communicating with microwave equipment in ETC lanes through "on-board electronic tags + IC cards." 2. By applying combined networked electronic toll collection technology at highway toll stations, the highway electronic toll collection system improves the traffic capacity of toll stations, alleviates congestion, and provides highway users with safe and convenient electronic payment and passage services. Using the electronic toll collection system can reduce vehicle wear and fuel consumption, decrease air pollution, achieve energy savings and emission reductions, and benefit environmental protection.
