Use the following values when a tractor is attached to a trailer. Note that there is only a single performance value for rigs, regardless of what type of cab is attached. Dark Future doesn't really go into detail for cargoes and the like, but it is assumed that the larger the cab, the greater the amount of cargo carried.
| Acc. | Speed | Brake | Non HE | HE |
Tractor with empty trailer | 5 | 70 | 10 | -2 | +2 |
Tractor with half-full trailer | 4 | 67 | 9 | -2 | +2 |
Tractor with full trailer | 3 | 65 | 8 | -2 | +2 |
