Managed motorways utilize electronic gantry signals and dedicated roadside infrastructure to regulate traffic flow and manage hazards. Match each active motorway signal or roadside feature to its corresponding legal requirement or operational rule.
- Illuminated Red 'X' displayed on an overhead gantry above a laneThe lane is closed to all traffic; you must not travel in this lane
- Speed limit numeral enclosed inside a red ringLegally enforceable maximum speed limit that drivers must obey
- Emergency Area (EA) with blue signage and orange surface markingsDesignated stopping refuge reserved strictly for breakdowns and genuine emergencies
- Downward pointing green arrow displayed above the hard shoulderHard shoulder is open and available for use as an active running lane
Cevap
The Red 'X' matches with 'The lane is closed to all traffic; you must not travel in this lane'; the speed numeral inside a red ring matches with 'Legally enforceable maximum speed limit that drivers must obey'; the Emergency Area matches with 'Designated stopping refuge reserved strictly for breakdowns and genuine emergencies'; and the downward green arrow above the hard shoulder matches with 'Hard shoulder is open and available for use as an active running lane'.
Each feature corresponds precisely to Highway Code regulations: an overhead Red 'X' mandates an immediate lane closure; a speed limit in a red circle sets an enforceable maximum speed; an Emergency Area serves as a dedicated emergency refuge; and a green arrow over the hard shoulder indicates that dynamic lane use is permitted.
