Safe zones are important for 3 reasons:
You can pit/spec there without losing your trip (see bonus system
You can pit/spec there without being pit-fined (see bottom)
The primary safe-zone is usually the active pit-lane. TC tracks do usually offer 2, sometimes 3 safe-zones.
Safe-zones are indicated in the location-bar as Safe Zone
Note: Please be careful when moving close to the end/side of a Safe-Zone, ie pit-wall. Insim may sometimes falsely assume you're outside.
Pit fines were introduced to encourage players to drive more responsibly, crash less and drive back to pits instead of using Shift + P. If you leave the track outside a safe-zone, you will be fined a €500 tow charge. Nevertheless, you're allowed to leave the track wherever you want once time every 5 minutes. The pit-timer (shown display at the top) will start counting down from 5:00 when you leave pits. Once it reached zero, it will show Free Pit
. That means you can leave without getting fined.
Note: You won't get fined when leaving the server. You also don't need to drive back to pits to leave (unlike other cruise-servers). Leaving the server will never be fined or otherwise punished.
WARNING: Users constantly disconnecting and reconnecting to the servers to avoid the pit fine, will be dealt with accordingly.
