In Klarfeld v. State of California (1983) 142 Cal. App. 3d 541, the court determined, in light of the federal regulations and administrative interpretation of the above statutes, that it was reasonably clear sections 26708 and 26708.5 proscribed the driving with and the application of transparent coating to a vehicle's windshield or its front windows to the sides of the driver unless certain exceptions applied. (Id. at pp. 547, 550.) Further, under the federal standards tinted front side windows must allow 70 percent light transmission. (People v. Niebauer (1989) 214 Cal. App. 3d 1278, 1290.) However, any after-factory tinting is illegal regardless of the amount of light transmission allowed by the tint. (Klarfeld v. State of California, supra, 142 Cal. App. 3d at p. 550.)
