Will traffic police check the decals on both sides of a car?

As long as the area covered by the decals does not exceed 30% of the entire vehicle, traffic police will not check it, and it will also pass the annual inspection without any issues. Relevant regulations: Since the firefighting-specific red color, the engineering rescue-specific yellow color, and the national administrative law enforcement-specific white-on-blue color scheme are all designated for special-purpose vehicles, ordinary vehicles are not allowed to use them. Safe driving: Sprayed or pasted logos or advertisements on the car body must not affect safe driving. The area covered by car decals must not exceed 30%. As long as the area covered by the decals does not exceed 30% of the entire vehicle, traffic police will not check it, and it will pass the annual inspection without any issues. If it exceeds 30%, an application for record filing should be submitted to the traffic management department.
I've been driving for over a decade, and putting small decals on both sides of the car body is usually not a big issue, but traffic police do check them. The key is the size and placement of the decals. The regulation states that the total area of car body decals should not exceed 30%. If they are too high or too large, they might be considered modifications and checked. My friend covered an entire side with a pattern, and the traffic police stopped him, saying it exceeded the limit, and fined him 200 yuan. Don’t let the decals cover the license plate or windows—that will definitely result in a fine and is also dangerous. Before applying decals, I suggest taking a photo with your phone and measuring the area ratio to ensure compliance. Also, be mindful when driving—avoid reflective materials that could interfere with visibility. Safety comes first; flashy decals are no substitute for steady driving. If you get stopped, explaining clearly or removing the decals on the spot is better than resisting. Knowing traffic rules well can save you a lot of trouble.
