Tennessee drivers caught with obscene or patently offensive bumper stickers, window signs or other markings on their vehicle visible to other drivers face an automatic $50 fine. The law also includes movies other drivers can see playing inside of vehicles, including adult films. Tennessee code 55-8-187 had allowed judges to decide on a fine from $2 to $50 based on their opinion.
Democratic State Representative Gary Moore, of Joelton, one of the sponsors of the bill introduced the bill to stiffen the fine after he got several angry calls from constituents. Drivers question if the law violates their rights to free speech.
