[Scenario]

I don't know what command processor you use, but if you have the /seatbelt command coded in ZCMD, something like this could work:

pawn Код:

public OnPlayerExitVehicle(playerid, vehicleid)
{
    // You should perform a check here to see if they have the seatbelt on, I added an example below.
    if(pSeatbelt[playerid] == 1) return cmd_seatbelt(playerid, params);
    return 1;
}
