Tornado season has violently started in the u.s already so take it from a hardened Midwesterner who has been on the highways and interstate when the radio starts doing the RRRRRRRNGH. RRRRRRRNGH. RRRRRRRNGH. BEEEEEEEEEP thing:
DO NOT TAKE SHELTER UNDER AN OVERPASS. EVEN IF YOU CLIMB UP THE HILL THING. CONGRATS YOU JUST ENTERED A WIND TUNNEL DURING A TORNADO. DON'T DO THAT
What to do if you are driving and there is a tornado:
If you can reach a building in which to shelter, do so.
If it is moving away from you/you can turn and drive away from it, do that.
If you can't do that, pull over and get to lower ground. A ditch, a ravine, any noticeably lower ground. Lay flat on your belly and cover your head.
If you can't do THAT, stop your car and pull over. Stay buckled up but get as low as possible, covering your head with your hands, and ideally your whole body with a coat or blanket in case windows break or debris is thrown into the car.
And as OP said, never, ever, EVER shelter under an overpass or in a tunnel.
