When driving on a smart motorway or active traffic management section, electronic signs and road infrastructure convey critical regulatory rules. Match each overhead signal or infrastructure feature to its corresponding legal rule or operational status.
- Overhead gantry displaying a number inside a red circleMandatory, legally enforceable maximum speed limit that must not be exceeded
- Red 'X' displayed on an electronic gantry above a laneLane is closed to all traffic; entering or proceeding along it is illegal
- Unlit overhead gantry signals across all open lanesNational speed limit of 70 mph applies under normal motorway regulations
- Blue sign displaying an orange SOS telephone symbol with distanceEmergency area ahead providing a refuge point equipped with an emergency roadside telephone
Cevap
Overhead number in a red circle matches mandatory speed limit; Red 'X' matches closed lane prohibition; Unlit gantry signals match national speed limit of 70 mph; Blue sign with orange SOS telephone matches emergency area refuge point.
Each feature corresponds to its legal designation under the Highway Code: red circles convey mandatory orders (speed limits), a Red 'X' mandates immediate vacation of closed lanes, unlit signals revert to the national speed limit (70 mph for cars), and the orange SOS marker directs drivers to an emergency refuge area.
