The ambulance station has two entrances. Also, in an emergency an ambulance can contravene a one way street if safe to do so.

Unless it's been rebuilt since we moved out of Manor Mount 18 months ago, the ambulance station only has one entrance/exit.

And Manor Mount/Davids Road is definitely two-way between the two ends of Pearcefield. What road markings or street signs give any indication that it is a one-way street? (Arrows on Google Maps don't have any legal status, fortunately.)

It would appear the whole of Manor Mount is now two-way between 3.30pm and 5pm most days of the week.

Think this is correct, although you'd be a braver man than me to attempt to drive round the the Manor Mt/David's Rd corner in the 'wrong' direction considering the speed and racing line of downhill traffic.
