Under the Highway Code for smart motorways, match each active traffic sign or signal to its corresponding legal requirement or function.
- Red 'X' displayed on an overhead electronic gantry signThe lane is closed and you must not drive in it
- White diagonal arrow pointing downwards to the leftYou must safely change lanes to the left as the current lane closes ahead
- Blue sign displaying an orange SOS telephone symbolIdentifies an emergency area for vehicles experiencing a breakdown
- Number displayed inside a red circle on an electronic gantryIndicates a mandatory maximum speed limit that must not be exceeded
Answer
Red 'X' matches 'The lane is closed and you must not drive in it'; White diagonal arrow pointing left matches 'You must safely change lanes to the left as the current lane closes ahead'; Blue sign with orange SOS phone matches 'Identifies an emergency area for vehicles experiencing a breakdown'; Number inside a red circle matches 'Indicates a mandatory maximum speed limit that must not be exceeded'.
On smart motorways, overhead signals convey specific legal instructions: an illuminated Red 'X' strictly prohibits driving in that lane; a diagonal arrow instructs drivers to change lanes safely ahead of a closure; the blue sign with an orange SOS phone marks an emergency area; and a speed limit displayed inside a red circle is a legally binding mandatory limit.
