The introduction of smart motorways has been a controversial venture by the government to say the least.
Campaigners have previously raised safety concerns about the technology, which includes traffic management methods to increase capacity and reduce congestion.
One such method is the use of red X signs, which indicate a full lane closure.

As of June last year, motorists who ignore the warning signs will be slapped with an automatic fine and points on their driving licence.
The punishments came in the wake of RAC research finding too many motorists dangerously ignore the red X signs.
According to Highways England, the red X sign can mean there's been a closure for a number of reasons.
A spokesman said: "The ‘red X in force’ message is an advisory reminder for motorists travelling on Smart Motorway sections.
"Red Xs are displayed on overhead electronic signs to close lanes for several reasons, including an accident or breakdown, debris in the carriageway, or because of a person or animal on the road.
"Lanes are also closed to help emergency services get through or to provide a safe space for road workers."
