The National Limousine Association is coming to aid of not-so-bright celebudorks who decide they have to drive after they've been drinking -- urging them to GET A RIDE!


TMZ has obtained an open letter sent to celebrity handlers and publicists, including reps for Britney, Lindsay and Paris, explaining that the NLA has more than 2,300 members -- and that finding a limo or town car over the holidays is not exactly rocket science. Plus, it reminds them that the fee for even a stretch limo is still far less than "DUI fees." Amen and hallelujah!

Remember, people: If you're tipsy, don't drive. And remember to tip your drivers!
