Never Lose Progress

Your progress is saved atomically. Game crash or PC shutdown? No problem. SimDuty restores the exact state of your trip.

Real Driving Rules

Hours of Service rules (USA, Canada, Brazil, EU) with dynamic switching. Rest, drive, and shift cycles calculated precisely.

Trip Proof

Every event is logged in a cryptographically chained Ledger (SHA256). Ideal for VTCs requiring proof of integrity.

Know Your Profit

Track every expense: fuel, tolls, fines. See exactly how much that speeding ticket cost you.

Smart HOS

No more math. No more fines.

SimDuty manages your Drive & Rest times automatically. Just drive until the clock turns red, then rest. It's that simple.
