Chariots cannot voluntarily move over obstacles or difficult terrain, except to cross a river at a bridge or a ford, that is safe to cross. A chariot compelled to move over terrain it cannot normally move through is likely to be damaged as its wheels strike rocks, its body becomes entangled in undergrowth, or it careens over a wall. If forced by circumstances into difficult terrain or over an obstacle, the chariot sustains D6 S6 hits. Apply these as hits from close combat and all the bits are directed toward the chariot. Chariots sometimes have to cross obstacles or difficult terrain, for example, if they are forced to flee from close combat. Chariots cannot charge over obstacles.
