Can I park in a loading bay?
If you park in a designated loading bay, you must be seen to be loading or unloading continuously. The maximum period allowed for this activity is displayed on the sign. You cannot use these bays if you are doing your weekly shopping.
I think that pretty much nails it... Straight from Wandsworth Council's website.
