On a smart motorway with active traffic management, match each overhead gantry signal to its correct legal meaning under the Highway Code.
- Red 'X' displayed above a laneLane is closed to traffic; drivers must not enter or proceed along this lane
- Speed limit numeral displayed inside a red circleMandatory maximum speed limit that is legally enforceable
- White arrow pointing diagonally downwards to the leftMove over into the lane to your left as soon as it is safe to do so
- National speed limit symbol (black diagonal stripe on a white circular background)Variable speed restrictions have ended and standard motorway limits apply
Cevap
Red 'X' matches with lane closure; Speed limit in a red circle matches with mandatory maximum speed limit; White diagonal arrow matches with moving into the left lane; National speed limit symbol matches with the end of variable restrictions.
Each gantry signal has a distinct legal definition under the UK Highway Code: a Red 'X' mandates an immediate lane exit/closure; a numeral inside a red circle sets an enforceable mandatory maximum speed limit; a diagonal arrow instructs traffic to merge into the adjacent lane; and the national speed limit roundel marks the end of variable speed control.
