Dear Mr. Hatt: This is in reply to your letter of June 8, 1987, to this agency askin about the legality of having 'a lighted sign on the side of a car door used for advertising purposes.' You have also asked whether such a sign would be a safety hazard to other drivers.; There is no Federal prohibition against installation of such a sign Its legality would be determined under local laws where a vehicle with a lighted sign would be registered and operated. You might wish to seek the advice of Arlington traffic officials and the Virginia State Police on this subject. It is not possible to say whether such a sign would be a safety hazard. Unlit advertising signs seem permissible in some areas on the sides of buses.; Sincerely, Erika Z. Jones, Chief Counsel
