Opening the tablet
Press F6 or type /tablet. The tablet opens the app for your current class automatically: Freight for truckers or Roadside for mechanics. Press ESC to close. Closing the tablet does not cancel your job; reopen it to check your progress.
Freight — for truckers
Clock in and visit the depot to accept an unlocked contract and collect a suitable rig. The contract shows cargo, route, pay and XP. Fleet manages your trucks; History shows past jobs and payslips. Click your rank to see milestones and claim rewards. You can check your fleet, history and ranks off duty, but contracts require a shift.
Roadside — for mechanics
As a mechanic, F6 opens Roadside directly. While on duty, take calls under Dispatch and follow GPS to the vehicle. Your rank badge opens XP, ranks and rewards, including off duty.
Need help with your own vehicle? From the driver seat, press K and choose Assistance: it shows the most the call can cost; press Enter twice to call. Mechanics see what is damaged, so there is nothing to fill in.
