Stuck in the ground and glitched

I was on a special transport drive on a straight road at 37mph when the front of the truck glitched halfway into the freeway. My truck slowly died, going to 100% damage, and I had to watch. I could do NOTHING! Anyway... it's a special transport so pressing F7 and asking for roadside service is out. I'm stuck and the game only loads to this wretched spot. Please help.
