The plastic under the car door is called the door seal strip. The car door requires good sealing performance, dustproof, waterproof, and sound insulation. In addition to the reasonable size matching between the door and the car body, the important part is the seal strip embedded or pasted on the door frame and the door. Sealing is an important indicator of the overall quality of the car, and the car seal strip product is one of the important components that determine the quality of this indicator. The seal strip is a rubber product with a hollow cross-section, and its softness allows it to fill gaps of different sizes. When the gap is large, the pressure on the seal strip is small, and when the gap is small, the pressure on the seal strip is large.

What to Do If ETC Fails to Deduct Fees on the Highway?

If you have already passed the exit but the ETC did not deduct the fee, the fee from the previous trip can be deducted together the next time you exit a toll station. If the toll station cannot resolve this issue, you need to bring your ID card, vehicle registration certificate, and OBU device to the local ETC service center for fault inspection. How ETC Works: Through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to perform backend settlement processing with the bank. This allows vehicles to pass through highway or bridge toll stations without stopping while still paying the required fees. Where ETC Can Be Installed: For small vehicles such as cars and minivans, the OBU device is installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC Installation Requirements: The height should be no less than 1.2 meters and no more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane).
