A chariot can continue to fight so long as it has at least one crewman left. If all its crew are slain, and assuming it can still move, then the chariot will move randomly in its own movement phase. This is worked out along with other compulsory movement (see the Movement section). The chariot rampages 2D6" up to its maximum speed in a completely random direction. This can be established using the Scatter dice. If you roll a double then the creatures collapse with exhaustion before the chariot moves and the model is removed from the battle. Otherwise, the chariot model is moved the distance indicated. If the chariot collides with troops then it comes to a halt and a round of hand-to-hand combat follows just as if the chariot had charged.
