Zorluk: ZorMotorway Signs and Signals

Motorway electronic matrix signals communicate hazard warnings, lane directions, and statutory closures through distinct light colours and mounting locations. Match each motorway matrix signal description with its correct legal meaning or mandatory driver response under the UK Highway Code.

  • A matrix signal situated on the central reservation displaying flashing amber lightsWarns of a temporary hazard or advisory condition that applies across all lanes of the carriageway
  • A matrix signal situated on the central reservation displaying flashing red lightsIndicates a mandatory instruction not to proceed past the signal in any lane (the entire carriageway is closed)
  • An overhead gantry signal above a single lane displaying a diagonal white arrow pointing down to the left with flashing amber lightsInstructs drivers to change lanes safely to the left ahead of an upcoming lane closure
  • An overhead gantry signal above a single lane displaying a red 'X' accompanied by flashing red lightsImposes a mandatory prohibition against driving in that specific lane beyond the gantry

Cevap

The matrix signal with flashing amber lights on the central reservation matches the carriageway-wide hazard warning. The central reservation signal with flashing red lights matches the mandatory stop for all lanes. The overhead diagonal left arrow with amber lights matches the instruction to move safely into the left lane. The overhead red 'X' with flashing red lights matches the mandatory prohibition against driving in that individual lane.
Motorway matrix signals are categorised by mounting location and illumination colour. Central reservation signals govern the entire carriageway: flashing amber lights issue advisory warnings for all lanes, whereas flashing red lights legally prohibit traffic from proceeding beyond the signal in any lane. Above individual lanes, a diagonal white arrow with amber lights instructs drivers to merge safely in the direction indicated, while a red 'X' with flashing red lights constitutes a mandatory lane closure that drivers must not enter or continue along.

Adım Adım Çözüm

1
Determine the physical mounting location of each matrix signal to establish its lane scope.
Signals positioned on the central reservation apply universally across all lanes of the carriageway, whereas individual overhead gantry signals apply strictly to the specific lane directly underneath.
Highway Code Rule 256 dictates that mounting location defines whether a signal governs a single lane or the entire carriageway.
2
Differentiate between flashing amber and flashing red light configurations.
Flashing amber lights provide advisory hazard warnings or directional lane-change instructions, whereas flashing red lights impose mandatory prohibitions that carry strict legal compliance.
Highway Code Rules 257 and 258 establish distinct legal tiers: amber indicates caution or impending restriction, while red indicates an absolute prohibition.
3
Match each signal's mounting location and visual symbol to its definitive regulatory requirement.
Central amber corresponds to all-lane advisory warnings; central red corresponds to all-lane mandatory closure; overhead diagonal arrow corresponds to moving left; overhead Red X corresponds to single-lane closure.
Synthesising signal position, colour, and graphic symbols yields the correct legal match for each item.
