To steer or maneuver a mount or vehicle in the right direction, a mounted character must make a dice roll using his/her Riding (including relevant specialisms) + CO..
The difficulty depends on how difficult the course that the character is trying to negotiate and how fast the character is travelling as follows:
| Course | Slow speed (e.g. walk) | Average speed (e.g. trot) | Fast speed (e.g. canter) | Breakneck speed (e.g. gallop) |
| Easy (e.g. steady direction, gentle turn) | 1 | 2 | 4 | 6 |
| Average (e.g. several twists and turns) | 3 | 5 | 8 | 10 |
| Difficult (e.g. trail up a canyon wall) | 6 | 8 | 11 | 14 |
If the dice roll fails, the mount or vehicle will veer off course - the amount of course deviation depends on the amount by which the dice roll is failed.
