# How to Configure Speed Limiters & Police in ATS

> Customize police fines and truck speed limiters on your ATS server to create either a realistic highway simulation or a fast-paced arcade racing environment.

## Establishing the Rules of the Road

Whether your goal is a hyper-realistic simulation with strict law enforcement or a high-speed racing environment across the American highways, customizing these core mechanics is essential. American Truck Simulator (ATS) allows for granular control over police activity and vehicle performance through its server configuration.

## Modifying Global Server Rules

The primary behavioral constraints for your server are defined within the `server_config.sii` file.

<Steps>
  <Step title="Access the File Manager">
    Log in to your [Game Panel](https://panel.freakhosting.com), select your ATS server, and navigate to the **Files** tab.
  </Step>

  <Step title="Locate the Configuration File">
    Find and open the `server_config.sii` file located within your server's configuration directory.
  </Step>

  <Step title="Control Traffic Offences">
    Locate the `traffic_offence` parameter to manage police interactions:

    * **`true`:** Players receive monetary fines for speeding, red-light violations, and collisions (Sim-Ready).
    * **`false`:** Law enforcement actions are disabled, and no fines are issued (Arcade-Ready).
  </Step>

  <Step title="Define Speed Constraints">
    Find the `truck_speed_limit` line to establish vehicle caps:

    * **`0`:** Disables the internal speed limiter entirely.
    * **`65.0`:** Implements a hard cap at 65 MPH (or your preferred numerical value).
  </Step>
</Steps>

## Defining Your Community Tone

The combination of these settings directly influences the type of drivers your server will attract.

<Tabs>
  <Tab title="Professional Realism">
    For a serious trucking experience, we recommend enabling `traffic_offence` and setting a realistic `truck_speed_limit` (typically 65.0 or 75.0 MPH). This configuration rewards disciplined driving and promotes synchronized convoy maneuvers.
  </Tab>

  <Tab title="Casual Arcade & Racing">
    If you are hosting a high-stakes truck race or a casual social event, set the speed limiter to `0` and disable traffic offences. This allows drivers to push their customized rigs to their maximum mechanical limits without penalty.
  </Tab>
</Tabs>

<Warning>
  ### Server Initialization

  Updates to these variables are not dynamic and require a full server restart to take effect. Always verify these settings before publicizing a scheduled event to ensure a consistent experience for all participants.

## Technical Details

<AccordionGroup>
  <Accordion title="Unit of Measurement">
    In the `server_config.sii` file, speed is generally calculated in kilometers per hour internally, even if your in-game dashboard displays MPH. Ensure you verify the in-game behavior after setting a custom limit.
  </Accordion>

  <Accordion title="Client-Side Overrides">
    Note that the server-side speed limiter acts as a hard cap. If a player has their own local limiter enabled at a lower speed, they will still be restricted by their client settings.
  </Accordion>
