Modifying Server Rules

Locate the server_config.sii file in your server’s configuration directory.
  • Police Enforcement: Set traffic_offence_police to true (Realism) or false (Arcade) to control if players receive fines for traffic violations.
  • Speed Limiter:
    • truck_speed_limit: 0 (Disabled - Unlimited speed).
    • truck_speed_limit: 65.0 (Enabled - Hard cap at 65 MPH).

Syncing Settings

Changes to these variables only take effect after a server restart. If you have “Convoy Racing” events planned, ensure the speed limiter is set to 0 well in advance.
