[LeLukas]

Obstructing the rear windshield of a car is considered illegal. Both the front and rear windshields, as well as the front engine hood and trunk lid, are not allowed to be severely obstructed. Below is relevant information about car windshields: 1. Function: The front windshield of a car is primarily made of laminated tempered glass or zoned tempered glass, capable of withstanding strong impacts. 2. Maintenance methods: Use windshield washer fluid appropriately. During regular windshield maintenance, choose the right washer fluid based on the season and weather conditions. There are mainly three types: summer windshield washer fluid, winter antifreeze windshield washer fluid, and special-effect antifreeze windshield washer fluid.
