When you run a race or a car meet, vanilla GTA will delete cars that are "unoccupied." A premium Traffic Menu allows you to toggle Freeze Traffic State or No Despawn for a radius around the meet. This ensures the 50 show cars stay parked even if no one is sitting in them.
To prevent abuse, the menu should be restricted. In server.cfg: traffic menu fivem
add_ace group.admin "command.traffic" allow
add_principal identifier.steam:110000112345678 group.admin
Then, in the client script, wrap the command: When you run a race or a car
if IsPlayerAceAllowed(PlayerId(), "command.traffic") then
RegisterCommand('traffic', OpenTrafficMenu, false)
end
Most modern frameworks (like QBCore) come with a built-in admin menu that has robust traffic controls. While not flashy, they are the most stable because they hook directly into the framework’s resource management system. Then, in the client script, wrap the command:
Running a 1980s Vice City themed server? Use the traffic menu to block all modern supercars. Running a post-apocalyptic server? Reduce traffic to 5% and only spawn rusty, beat-up vehicles. The Traffic Menu turns your server into a theme park.
