If a vehicle does not move it can shoot all its weapons up to their maximum range. Rapid Fire weapons can shoot once up to 24", or twice up to 12", otherwise Heavy and Assault weapons shoot the number of times listed.
If a vehicle moves up to 6" it can shoot one weapon. This can be any weapon, including a weapon held by a driver or crew member, but it can only shoot one weapon. Rapid Fire weapons can shoot once at long range, twice at short range, otherwise Heavy and Assault weapons shoot the pre-requisite number of times.
Note that the normal restrictions for infantry moving and shooting don't apply to weapons fitted to vehicles. So a heavy weapon mounted on a tank can still shoot even though the tank may have moved.
Vehicles that have moved more than 6" do not shoot at all.
Note that a twin-linked weapon counts as a single weapon for the purposes of shooting so it may be fired on the move.
Fast vehicles and Walkers follow their own versions of this rule, allowing them to fire more freely on the move.
