Check your physics book. If the road way lies below the parabolic path that the truck would take through the air, given its initial speed and direction corresponding to the slope of the road, the vehicle will leave the ground, at least momentarily. You can probably take the inclination a horizontal, assuming that the truck is at the crest of the bridge, and figure the parabola on that basis.
