What is the difference between the symbols for the front windshield and the rear windshield?

Here are the differences between the symbols for the front windshield and the rear windshield: Shape difference: The symbols for the front windshield and the rear windshield represent the wipers, mainly the wipers and washers for the front windshield glass and the rear windshield glass. The semicircular one is for the front windshield, while the square one is for the rear windshield. Front windshield: If there is a single semicircle with a line, it represents the front windshield wiper. If there are two curved water lines above it, it represents both the wiper and washer. Rear windshield: The rear windshield follows the same representation, but the window pattern is square without any curves.
As a seasoned driver with over a decade of experience, I often observe the details of vehicles while driving. The markings on the front windshield and rear windshield differ significantly. The front windshield typically displays more information, such as the Vehicle Identification Number (VIN), safety certification codes, and manufacturing date, which are etched in a small corner of the glass. These are designed to be compact to avoid obstructing the driver's view, primarily due to regulatory requirements aimed at ensuring driving safety. In contrast, the markings on the rear windshield are much simpler, mostly consisting of icons for heating and defrosting functions—a circle with wavy lines—or occasionally a few antenna symbols, as they do not directly affect the driving visibility. I’ve noticed that some cars even have minimal or no obvious markings on the rear windshield. Overall, the number and complexity of markings are far lower on the rear windshield compared to the front. This reflects how, in automotive design, the front windshield carries more critical functions and information, while the rear windshield focuses more on practical auxiliary features.
I'm a car enthusiast who enjoys tinkering with vehicle maintenance. The contrast between the markings on the front and rear windshields is quite interesting. The densely packed small print on the front windshield typically includes the VIN code and safety standard numbers, such as DOT or ECE certifications, positioned in corners where they minimally obstruct visibility for easy technician inspection. The rear windshield, however, usually features minimalistic symbols for heating elements, occasionally accompanied by antenna or rain sensor information, but overall has significantly fewer markings. This difference stems from functional priorities: front windshield markings serve compliance and safety purposes, requiring quick identification, whereas rear windshield designs prioritize unobtrusiveness since their primary function is defrosting. I'd advise owners who notice abnormal markings to first check the front windshield—it's often the first indicator of potential issues.
