Parking notices are usually so badly written and designed that they appear to be deliberate traps to attact fines (see Martin Cutts's worthy campaign on this).
But I saw this sign at Westbury railway station* the other day, and thought: nice one, Apcoa.
I stumbled on the term 'knee rail', which was new to me although in context understandable. Off the central road the ground surface is gravel so they have painted white bars on the low rails at the end of parking bays.
*'Railway station' is old-geezer for train station.
