Car window tinting is not illegal. Below are the precautions and identification methods for car window tinting: Precautions for car window tinting: When performing car window tinting, it is necessary to inspect the workshop where the work will be done. Car window tinting should be carried out in a fully enclosed dust-free workshop. During the tinting process, there should be no floating dust in the air. Also, observe whether the workshop has spray dust suppression facilities, which can provide a better environment for car window tinting. The workshop should also have a humidifier to ensure the proper environment for tinting. Identification of car window tinting: Make a general judgment of the car window tinting based on its color. Generally, high-quality car window tinting uses lighter colors that are comfortable for the eyes, such as light green, sky blue, gray, brown, and natural colors. The tinting color should not fade.

I've been driving for over 30 years, and whether car window tinting is illegal depends on specific regulations and application methods. In China, tinting regulations are quite strict - for example, the light transmittance of front windshields must exceed 70%, otherwise you'll face fines or removal orders if caught by traffic police. I once got fined 200 yuan after a minor accident caused by poor nighttime visibility from dark tint I installed to stay cool. Excessively dark tint isn't just a legal issue - it creates safety hazards, especially during rain or night driving when traffic signals become hard to see. Always check local traffic laws before tinting and choose professional shops installing compliant films with proper light transmittance to avoid trouble. Don't risk safety for temporary comfort - safety should always come first. Regularly inspect tint condition to prevent degradation affecting visibility.

A friend just bought a car and applied ultra-dark tint, only to be pulled over by the police and warned for violating regulations due to insufficient light transmission affecting safe visibility. Standards vary by region—some allow darker side windows but require the windshield to remain clear. I've seen new drivers apply low-transmittance tint in summer while overlooking the law, getting fined and having to redo it. It's not just about the cost; the potential danger is significant, especially when turning at night and risking collisions. When choosing tint, opt for brand-certified products and ensure a light transmittance of at least 70% to stay safe. Test the light intensity yourself, and consult the dealer if unsure. Maintain clear driving visibility—don’t let personal preference override the rules.

Car window tinting violations are primarily based on light transmittance requirements. For example, in China, the front windshield must have over 70% light transmittance. Excessively dark films can obstruct visibility and increase accident risks, hence being deemed non-compliant. I've learned that side windows can have slightly lower but still limited transmittance, avoiding fully reflective designs. Choosing certified films saves hassle, and checking manufacturer specifications during installation ensures compliance. Remember, violations may result in fines or failed annual inspections. While tinting offers sun protection and heat insulation, safety comes first - ensure proper light transmission. Use professional tools to test transmittance rather than relying on intuition to choose dark shades that may cause future issues.
