Windshield requirements

  • All vehicles are required to have safety glazing material for the windshield and windows. This material is glass that is manufactured in a way that lessens the potential for shattering and flying glass.

  • Anyone driving a vehicle that does not have safety glazing material for the windshield must wear goggles, face shields or safety glasses at all times while the vehicle is being operated.

  • Windshield wipers that are controlled by the driver and in good working condition are required on all vehicles for the removal of rain, snow, sleet and other moisture.
