A camera dolly has wheels that can be positively steered via a steering bar operating a corrective and crab mode steering system. A spring holds a steering transmission of the steering system into the crab mode. The dolly operator may shift from the crab mode into the corrective mode by momentarily pushing down on a plunger on the steering bar, when the wheels are straight. After performing a corrective steering maneuver, the spring causes the steering system to automatically return to the crab steering mode when the wheels are steered back to the straight position.
