Washington State's Department of Licensing outlines guidelines and specifications for all vehicles sold and repaired in the state. The DOL breaks down the different parts of vehicle guidelines, including windshields.
Required
All vehicles operating on Washington state highways must be equipped with a front windshield, according the Washington State Department of Licensing.
Keep It Clear
All vehicles must be equipped with a device to clean off rain, snow and other moisture from their windshields.
Damage
If a windshield is damaged, the car may not be sold. Likewise, if you are replacing a damaged windshield, it may not be replaced with another, less damaged windshield.
Tint
Washington's window tint law states that a non-reflective tint is allowed 6 inches down from the top of the windshield.
