You see this sign on a smart motorway. Which lane can you use?

Explanation: Mandatory speed-limit signs above the hard shoulder and all other lanes show that you're on a smart motorway. In this case, you can use the hard shoulder as a running lane. You must stay within the speed limit shown. Look well ahead for any vehicles that have broken down and are blocking the hard shoulder.
