vehicles

Hello, In my server people always spawn jeeps/airboats and kill people. Which i don’t like. So i ask can someone give me a good that only block jeeps/airboats to normal players and admins can spawn?

come on please? I know its not hard

[lua]
hook.Add(“PlayerSpawnVehicle”,“lol”,function(p,c)

if (c == "prop_vehicle_jeep" or c == "prop_vehicle_airboat") and !p:IsAdmin() then

    return false
end

return true

end)
[/lua]

Thanks
