Match each smart motorway signal or feature to its correct legal meaning and driver requirement.
- Solid illuminated Red 'X' displayed above a laneMandatory lane closure: you must not proceed in this lane and must safely move into an open lane as soon as possible.
- Speed limit displayed within a solid red ringMandatory speed limit: you must not exceed this numerical limit under any circumstances while it is illuminated.
- Speed limit displayed with flashing amber lights and no red ringAdvisory speed limit: you should adjust your speed for prevailing hazards, though it is not legally binding on its own.
- Emergency Area (EA) indicated by blue signs with an orange SOS symbolDesignated refuge area: strictly reserved for vehicle breakdowns or genuine emergencies, never for routine stopping.
Answer
Each signal matches its specific legal obligation: a Red 'X' indicates a mandatory lane closure; a red ring denotes a legally enforceable speed limit; amber flashing lights signify an advisory speed recommendation; and an Emergency Area provides refuge solely for breakdowns and emergencies.
On smart motorways, overhead signals communicate enforceable traffic management rules. A Red 'X' strictly prohibits driving in that lane; numbers within a red circle set a mandatory statutory limit; flashing amber lights without a red ring provide advisory warnings; and Emergency Areas are reserved exclusively for breakdowns and emergencies.
