Zorluk: Çok zorSmart Motorways and Active Traffic Management

A motorway is operating under a Dynamic Hard Shoulder (DHS) system. The overhead gantry signals for the three standard carriageway lanes all display a mandatory speed limit of 50 mph inside a red ring. However, the gantry signal positioned directly above the hard shoulder is completely unilluminated. If your vehicle suddenly suffers a severe mechanical failure while you are travelling in the left-hand standard lane, what is the legally required course of action?

  1. Safely move onto the hard shoulder and stop, as the unilluminated signal confirms it is currently operating as a traditional emergency refuge.Cevap
  2. B
    Proceed to the nearest designated Emergency Area (EA) without stopping, because a blank signal indicates the hard shoulder is actively open as a live traffic lane.
  3. C
    Halt your vehicle in your current lane and activate hazard lights, because an unilluminated gantry over a DHS means that section of tarmac is completely out of bounds.
  4. D
    Steer onto the hard shoulder but match the 50 mph limit before gradually stopping, since mandatory limits on smart motorways apply across all paved surfaces.

Cevap

You should safely move onto the hard shoulder and stop, because the unilluminated signal above it means it is not being used as a live lane and is available as an emergency refuge.
The correct action is to move onto the hard shoulder and stop. Under the Highway Code for Dynamic Hard Shoulder (DHS) motorways, you MUST NOT use the hard shoulder as a running lane unless a specific speed limit is displayed above it. Because the signal is unilluminated (blank), the lane is closed to normal traffic and has reverted to a traditional hard shoulder, making it the correct and legal place to stop in an emergency.

Adım Adım Çözüm

1
Analyze the gantry signal displayed above the hard shoulder.
The signal is completely unilluminated (blank).
On a Dynamic Hard Shoulder (DHS) system, the status of the hard shoulder changes based on the specific signal displayed directly above it.
2
Determine the legal meaning of a blank signal over a DHS.
It indicates that the hard shoulder is NOT currently open to traffic as a running lane.
Unlike standard lanes where a blank signal means 'national speed limit applies', a blank signal over a DHS means the lane reverts to its traditional purpose.
3
Apply the rule to the emergency scenario.
Since it is operating as a traditional hard shoulder, it is safe and legal to use it to stop the broken-down vehicle.
Highway Code rules state that a hard shoulder must only be used for emergencies unless a speed limit is actively displayed above it.
