Decoding Car Window Markings: A Comprehensive Guide

My friend, a long-time truck driver for a transportation company in Long Bien District, once confided in me about the challenges of buying a used vehicle. He said that inspecting the vehicle was difficult, but paying attention to the markings on the car windows was even harder. “Sometimes, the markings on the glass are like a protective talisman, indicating whether the car is ‘clean’ and ‘durable’,” he chuckled.

His story reminded me of the Dongfeng trucks that ply the streets of Hanoi every day. The markings on car windows, seemingly insignificant, actually contain more important information than we think.

What Are Car Window Markings?

Car window markings are a set of letters, numbers, and symbols printed on the windshield, side windows, or rear window of a vehicle. They provide information about the manufacturer, glass type, safety standards, origin, and other special features of the glass.

Why Should You Care About These Markings?

Ensuring Safety

Car window markings help you identify the type of glass and its safety standards, allowing you to understand its strength and impact resistance, ensuring safety for yourself and passengers.

Choosing the Right Replacement Glass

When you need to replace your windshield or windows, understanding the markings on the old glass will help you choose a compatible replacement, ensuring quality and aesthetics for your truck.

Identifying a “Genuine” Vehicle

Carefully inspecting the markings on the car windows is also a way to identify the origin of the vehicle, avoiding the purchase of low-quality vehicles or those that have undergone repairs or glass replacements with unknown origins.

Types of Car Window Markings

1. Manufacturer Information

Usually, this is the logo or abbreviated name of the glass manufacturer, for example:

• AGC: Asahi Glass Company (Japan)
• FY: Fuyao Glass (China)
• VG: Viet Glass (Vietnam)

2. Glass Type

• Laminated: Safety glass consisting of two or more layers of glass bonded together with a PVB plastic interlayer, which helps hold the glass together when shattered, enhancing noise reduction and UV protection.
• Tempered: Tempered glass, heat-treated to increase its hardness and strength. When broken, tempered glass shatters into small, relatively harmless pieces.

3. Safety Standards

• DOT: Safety standard of the US Department of Transportation.
• ECE: Safety standard of the United Nations Economic Commission for Europe.
• AS: Australian Safety Standard.

4. Other Information

• Year of manufacture: Usually represented by the last two digits of the production year.
• Country code: Indicates the country where the glass was manufactured.
