Euro Truck Simulator 2 · Driver skill
Long-Distance skill
The Long-Distance skill relates to longer cargo contracts, which the starter guide says generally provide more money upon delivery.
How it works
The starter guide recommends Long-Distance as an early skill for hauling longer contracts. The overview says skill upgrades improve performance in their categories and affect how likely related jobs are to be offered and how lucrative they are. Neither passage gives level-by-level effects or exact payment changes.
