Looks like the residents of Llangadog have had even more unsuitable traffic 

 From a recent traffic report:

It's interesting that all the news reports of buildings being crashed into by 
lorries don't actually specify that the road in question has any official 
restrictions or signs about length, weight or width restrictions.

It's also interesting that lots of people are blaming foreign truck drivers.
Maybe if any official signage in the UK was clearly in metric units like the 
rest of the civilised world (sorry to offend any citizens of Burma, or the 
United States of America), it would be much clearer. Should a Polish 
articulated lorry driver driving a truck registered in the Netherlands with a 
trailer owned by an Italian company need to know that the combined truck and 
trailer is longer than 32 feet six inches?

Then they shouldn't need bizarre signs such as
