How long to wait after car window tinting before installing ETC?

[Marty]

You need to wait one month after car window tinting before reinstalling the ETC. ETC working principle: Through the on-board electronic tag installed on the vehicle's windshield, dedicated short-range communication is established with the microwave antenna in the ETC lane at toll stations. This utilizes computer networking technology to perform background settlement processing with banks, achieving the purpose of vehicles passing through highway or bridge toll stations without stopping while still paying the fees. ETC usage precautions: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the preceding vehicle in case its ETC device malfunctions or is absent. The recognized speed for ETC lane passage is 20km/h. Excessive speed may prevent reading vehicle device information, leading to failed fee deduction. Unauthorized removal or displacement of OBU devices, or detachment/loosening of ETC electronic tags will cause tag deactivation. These can be taken to the bank where the ETC card was issued or highway service offices for inspection. Non-deliberate loosening or detachment only requires reactivation. When using debit cards bound to ETC, insufficient balance may cause fee deduction failure. Follow on-site staff guidance to use manual MTC lanes with cash or card payment. Excessively thick windshields may cause poor signal reception. This is particularly noteworthy for vehicles that have had windshield replacements after accidents or modified front windshields.
