[HELP]Trailer

[Black2]

Hello,I have this script, it adds trailer to the vehicle can see, I wonder how do to disconnect the trailer when the vehicle he comes back doing what ever the trailer is there.

Any idea ? Thx.

function attachTrailer (theVehicle, seat, jacked ) 
    if ( getElementModel (theVehicle) == 514 ) then 
    local x,y,z = getElementPosition(theVehicle) 
        trailer = createVehicle ( 584, x-11, y, z)  
        setElementRotation (trailer, getElementRotation (theVehicle))    
        attachTrailerToVehicle (theVehicle, trailer)  
    end 
end 
addEventHandler("onPlayerVehicleEnter", getRootElement(), attachTrailer)

Use detachTrailerFromVehicle. I didn't understand when exactly the trailer should be detached.
