Question Author
Wow Tetjam, you answered someone else's question and I feel I have to add the expletive was an inspired touch. Well done you...
Neither I nor anyone I know has been cought speeding in this situation.
It is in fact a hypothetical question. However as 98% of the lower limit signage in (a rather large) city is uninforcable (due to the above) I wondered what the speed limit by law is.
If you know the answer please feel free to let me know otherwise I respectfully suggest you get your facts right and go and swear at someone else.
