A vehicle's Acceleration value is how many inches per turn it can increase its current speed. A pickup with an Acceleration of 5, for instance, can increase its movement by 5“ every action, up to its Top Speed. A vehicle can decrease its speed by twice its Acceleration (or more in a Hard Brake; see Maneuvers).

The player controlling the vehicle decides his speed at the beginning of his action, and moves it that many inches. The vehicle remains at that speed until the driver's next action, so record the current speed somewhere for the next round and in case it hits something.

Vehicles have some restrictions on maneuvering, particularly in how they turn. Use the Turning Template for normal turns, or perform a maneuver (see below) for tighter moves.

Action Cards: Vehicles move on their driver's Action Card. Driving is a free action unless the driver attempts a maneuver. Passengers act on their own initiative as usual.

Speed Kills: It's much easier to maneuver a vehicle slowly than it is at high speed. A vehicle moving over 15” a round on the tabletop inflicts a -2 handling penalty on its driver. A vehicle moving over 30“ inflicts a -4 penalty.

Difficult Ground: Slippery gravel, uneven ground, and mud are all difficult ground and work just as for characters on foot. Count each inch moved through such rough terrain as two, and apply a -2 penalty to all Driving rolls made while in rough terrain. Driving through rough terrain at over half of Top Speed requires a Driving roll every round.

Reverse: A vehicle can move up to half its Top Speed in reverse. Driving rolls made while in reverse suffer a -2 modifier.

Aircraft: Aircraft ignore terrain. Unless the aircraft has the ability to hover, it must move at least half its Top Speed each action. Climb isn't used in table-top battles–only in Chases.

Animals and Conveyances: Animals don't have to worry about Acceleration or Top Speed–they simply move their Pace (plus any running roll) each round. Animal-drawn transportation has an Acceleration equal to half the animal's basic Pace. Carts and wagons don't have a Top Speed because the animal simply moves its Pace as usual (plus a running die if it runs).
