    A legally enforceable mandatory speed limit of 50 mph is now in effect
  2. An advisory maximum speed limit of 50 mph is recommended due to a hazard aheadCevap
  3. C
    A minimum mandatory speed of 50 mph must be maintained to prevent traffic congestion
  4. D
    The lane is closing in 50 metres and traffic must immediately merge into the adjacent lane

Cevap

An advisory maximum speed limit of 50 mph is recommended due to a hazard ahead
Flashing amber lights on an overhead motorway gantry or roadside matrix signal indicate that there is a hazard ahead, such as an incident, adverse weather, or queuing traffic. When a number is displayed alongside flashing amber lights without a solid red ring, it represents an advisory maximum speed that drivers should follow for safety.
