Eats, shoots, and leaves!
There is a proposed new TRO to extend the restrictions on the high street to Sundays and BHs:
Medway Council download - Traffic Regulation Orders | Parking, roads, travel | Roads and pavements
The idea (I think) is normally access to that section of road is from the other end, but 10-4 Saturdays that is pedestrian only, so they have allowed access from this end on Saturday 10-4.
This looks like one of those cases where (as Gov agencies like to do) they have tried to dumb down things, but ended up making it so complicated in double speak that it's actually harder to understand.
I think it's supposed to say:
No vehicles
10 am - 4 pm
Except for access
on Saturdays
Based on the above that's not right either, better might have been:
No Vehicles except for:
Access only on Saturdays 10am - 4pm
If they implement the new TRO, it will be even more complicated and confusing!!
