A window acts like a sunscreen. It does not block all the UV radiation but it does block the most dangerous wavelengths of UV radiation. Glass absorbs short wavelength ultraviolet light, but it does pass 350 to 400 nanometer ultraviolets. While this longer wavelength ultraviolet is less harmful than the shorter wavelength variety, you can still tan or burn if you get enough exposure. You will burn much more quickly when driving with the windows down and exposed to the sun as compared to driving with the windows up and exposed to the sun.
