Where they start to apply and where they end
Supplementary signs detail the traffic arrangement: they show lane directions (F-10, F-11), warn of prohibitions beyond the intersection (F-5, F-6), guide along diversions (F-8, F-9), count down the distance to a motorway exit (F-14) and indicate lanes for specific vehicles. Lane directions given by sign F-10 are binding, just like the arrows on the carriageway.
