<P> Budweiser, the best - known Anheuser - Busch brand, has sponsored IndyCar drivers such as Mario Andretti, Bobby Rahal and Paul Tracy, as well as NASCAR Cup drivers such as Terry Labonte, Neil Bonnett, Darrell Waltrip, Bill Elliott, Dale Earnhardt Jr., Kasey Kahne and currently Kevin Harvick . Meanwhile, Miller has sponsored Al Unser, Danny Sullivan, Bobby Rahal, Rusty Wallace, Kurt Busch and currently Brad Keselowski . </P> <P> Furthermore, NASCAR mandates drivers under 21 not be permitted to wear any alcohol - branded sticker on their cars . In cases with below drinking age drivers, a specialised "Coors Pole Award - 21 Means 21" sticker is placed on such drivers' cars . One team, Petty Enterprises, refuses to participate in alcohol advertising and forfeits all alcohol monies and bonuses . </P> <P> For distilled spirits, teams must run a responsible drinking sticker clearly visible on the car . For Jack Daniel's, the theme is "Pace Yourself, Drink Responsibly", and includes on NASCAR's Web site a waving yellow flag warning drinkers . For Crown Royal, the television ads feature the car with the slogan "Be a champion, Drink Responsibly" and it acting as a pace car to drivers, warning them of responsibility . Jim Beam has radio ads and NASCAR mandated statements about alcohol control . None of the three, however, is a full - time sponsor, as they alternate sponsorship with other products unrelated to their firm on the car . (Jim Beam's parent, Fortune Brands, sometimes has its Moen Faucets replace Jim Beam on the car in selected races .) </P> <P> Although tobacco companies have been the main source of financial backing in Formula One, some alcohol brands have also been associated with the sport . For example, Martini appears on the Williams F1 car while Johnnie Walker has sponsored McLaren since 2006 . </P>
