The only way to claim a "zero tolerance" policy is to test everyone, otherwise...it's "random tolerance". NHRA will undoubtedly respond to that suggestion that they don't have the staff to administer that many tests on a daily basis. The two largest breweries (Anheuser-Busch & Miller) both have budgets for "responsibility" campaigns. It would be great public relations if they helped NHRA by supplying support staff to administer those tests. My Radio station receives a large monthly budget from AB advising our listeners to limit their drinking and not to drink and drive, so I know the money for something like this exists. Another source of help in each market would be M.A.D.D. They will always answer the call to help spread the message that drinking and driving is a terrible decision.
There are solutions available to NHRA that would solve (staff) the problem as well as give the sanctioning body the positive public relations they ultimately want.
Let's see if it really is "zero tolerance"...
