i dont know if you guys know this already or whatever but here it is anyway. if you are driving a truck or something like one (eg a trashmaster or an ambulance, spelling??)and if it falls over onto its side just move the d-pad in the direction that you fell (if you fell onto the left side hold it to the left, same with the right) and hold x, it will move back up but make sure to stop holding it just as its about to come back up, it will start rocking back and forward so just move the d-pad in the oposite direction to the way that you are rocking (if it moves to the right move the d-pad to the left, same with the left side) and tap the square button, keep doing it until it stopps rocking.
