Chariots cannot move over obstacles or difficult terrain, except to cross a river at a bridge or a ford. A chariot compelled to move over terrain it cannot normally cross is likely to be damaged as its wheels strike rocks, its body becomes entangled in undergrowth, or it careers headlong through a wall. If forced by circumstance into difficult terrain or over an obstacle, the chariot sustains D6 Strength 6 hits. These are randomly distributed among the chariot, crew, and creatures in the same way as hits from shooting (see below for a description of how to do this). Chariots sometimes have to cross obstacles or difficult terrain for reasons beyond their control, for example if they are forced to flee from close combat.
