`  == Non-mandatory or “suggested” speed limits ==  In addition to mandatory speed limits, the UK has non-enforceable “suggested speed limit” signs. They look somewhat like the US signs, only they are wider, with ``MAX SPEED`` to the left. There is no corresponding “end of suggestion” sign. Do other countries have a similar thing? (While they're unenforceable, they could probably be used to support a charge of “driving too fast for the conditions”.) It seems the US uses mandatory limits where in the UK a suggested limit would be posted. `
