Losing Control
A collision or a failed stunt can cause a driver to lose control of his vehicle. In these cases, the driver must make a Drive check to retain control of the vehicle. If this check is successful, the driver maintains control of the vehicle. If it fails, the vehicle goes into a spin. If it fails by 10 or more, the vehicle rolls. Remember that the check/roll modifier from Table: Vehicle Speeds and Modifiers applies to all Drive checks.
An out-of-control vehicle may strike an object or other vehicle. When that happens, a collision occurs (see Collisions and Ramming).
Spin: The vehicle skids, spinning wildly.
At character scale, the vehicle moves in its current direction a number of squares equal to the turn number for its speed, then ends its movement. Once it stops, roll 1d8 to determine its new facing: 1, no change; 2, right 45 degrees; 3, right 90 degrees; 4, right 135 degrees; 5, 180 degrees; 6, left 135 degrees; 7, left 90 degrees; 8, left 45 degrees. Reorient the vehicle accordingly.
At chase scale, the vehicle moves 1 square and ends its movement. Roll to determine its new facing as indicated above.
Roll: The vehicle tumbles, taking damage.
At character scale, the vehicle rolls in a straight line in its current direction for a number of squares equal to the turn number for its speed, then ends its movement. At the end of the vehicle’s roll, reorient the vehicle perpendicular to its original direction of travel (determine left or right randomly).
At chase scale, the vehicle rolls one square before stopping and reorienting.
At either scale, a vehicle takes damage equal to 2d6 x the character scale turn number for its speed (use the turn number from character scale even at chase scale). The vehicle’s occupants take damage equal to 2d4 x the character scale turn number for its speed (Reflex save, DC 15, for half damage).
