New 'major concern' raised with smart motorways by the AA

Another 'major concern' with smart motorways has been identified by the AA as the motoring organisation continues to rally for them to be axed by the Government.
Smart motorways have a vehicle breakdown rate nearly three times higher than conventional motorways, according to new figures released by National Highways - the Government-owned company responsible for 'M' roads in Britain - in response to a Freedom of Information request by the AA.
With 13 per cent of the nation's 1,900 miles of motorway network 'smart' stretches without a hard shoulder at any time, motorists risk being stranded without a safe place to pull off the road if their car suffers a mechanical issue.
The statistics show 56 per cent of breakdowns logged on England's motorways last year happened on smart sections.
That is despite the roads only making up a fifth of the nation's total motorway network and there being no new installations in the last two years after the Government cancelled construction of new stretches on safety fears.
The 141,149 smart motorway breakdown incidents recorded in 2024 was an average of 387 per day, the data revealed.
National Highways said the advanced technology installed on smart motorways means breakdowns on these roads are more likely to be detected.
However, the most recent smart motorway stocktake published in March highlighted a number of reported software outages that limited the capacity to identify drivers at risk.
Following analysis of 12 smart motorways section over a one-year period, the Office of Rail and Road - the independent watchdog monitoring National Highway - found that four failed to meet the target for detection rates, one didn't meet the target for false discovery rates, and two did not meet the target for average detection times.
The volume of breakdowns recorded on smart motorways has intensified the AA's long-standing concerns about their safety to the public after a number of fatal incidents occurred when vehicles stopped in live lanes were hit from behind.
Former prime minister Rishi Sunak cancelled all planned smart motorway projects in April 2023, citing financial pressures and a lack of public confidence in the roads.
Some smart motorway stretches are controlled schemes, which use variable speed limits and retain a hard shoulder. However, these cover just 7.3 per cent of the network, according to analysis by road safety charity, IAM RoadSmart.
Sections considered most dangerous are All-Lane Running smart motorways (13 per cent of the network) that have no hard shoulder whatsoever.
This is because motorists who are unfortunate enough to be involved in collisions, encounter vehicle issues or suffer punctures are required to pull into short emergency refuge areas that are spaced a maximum of 1.5 miles apart. If a car is rendered undrivable, it is often impossible to reach one off these safe pull-off areas.
Dynamic Hard Shoulder sections - which cover 3.3 per cent of the motorway network - do have a hard shoulders but these can be turned into live lanes in periods of heavy congestion.
AA president Edmund King told the PA news agency: 'For many drivers, fear of a collision on a smart motorway would be reinforced by witnessing a breakdown in a live lane, or frequently seeing vehicles in refuge areas.
'These new figures suggest that the chance of that happening is increasing – approaching 400 a day along 396 miles of smart motorway, even when including controlled stretches.
'Equivalent to one a mile each day, that inspires more motorists to stay out of lane one, thus increasing the chance of congestion.'
For the first time, figures published by National Highways show 251,448 breakdowns on England's motorways were logged last year.
That is an increase of 3 per cent from the previous year and a monumental 47 per cent jump compared with 2014.
The AA said free breakdown recovery in roadwork areas and monitoring of smart motorways have increased the number of incidents recorded by National Highways.
It believe the length of the motorway network can be ruled out as a major factor as it has only increased by 65 miles in the past decade.
Mr King said: 'It is a major concern that we are witnessing more than a quarter of a million breakdowns a year on the motorway network – and those are just the officially recorded ones.
'The situation does not appear to be getting any better.'
He added that drivers can reduce the likelihood of breaking down by taking measures such as having their vehicle regularly serviced, checking tyre conditions and pressure, and ensuring they have adequate fuel or charge.
The AA has long been campaigning for ministers to take further action by scrapping existing smart motorways.
King told the BBC in 2023 that the government needed to go further and restore a permanent hard shoulder to the hundreds of miles of existing smart motorway without one.
'Basically drivers don't trust them, the technology is not fool proof, and 37 per cent of breakdowns on smart motorways happen in live lanes. And basically those drivers are sitting ducks,' he said.
A National Highways spokesman said: 'Our latest analysis continues to show that overall, smart motorways remain our safest roads.
'We have upgraded the technology to detect stopped vehicles, improved response times to live lane breakdowns and installed more than 150 additional emergency areas giving people a place to pull over if they break down.
'Unlike other roads, smart motorways have technology in place to identify stopped vehicles, including breakdowns.
'This means more breakdowns are identified on smart motorways compared to other road types, and as a result these stats are not a reliable indicator of actual safety.'
In a poll of 13,500 UK drivers conducted by the AA earlier this year, a third said they feel 'a lot less safe' on smart motorways than they did three years ago.
In contrast, just two per cent of the panel said they feel more at risk on conventional motorways than they did in 2022.
A third responded saying they are more anxious driving on sections of smart motorway with dynamic hard shoulders and drivers generally felt more unsafe on any stretch of smart motorway where there is no hard shoulder, the study found.
As such, three in five of the nation's motorists said they want smart motorways scrapped entirely.
'It is time to accept so-called 'smart' motorways has failed and side with the majority of drivers who want the reinstatement of the hard shoulder,' the AA President said back in March.
What are the three types of 'smart' motorways and how do they work?
ALL LANE RUNNING (ALR)
All lane running schemes permanently remove the hard shoulder and convert it into a running lane.
On these types of motorway, lane one (formerly the hard shoulder) is only closed to traffic in the event of an incident.
In this case a lane closure will be signalled by a red X on the gantry above, meaning you must exit the lane as soon as possible.
All running lane motorways also have overhead gantry signs that display the mandatory speed limit.
Should drivers break down or be involved in an accident there are emergency refuge areas at the side of the carriageway for them to use.
Miles in total: 249.5 miles
Percentage of smart motorways in England: 55.1%
Percentage of all motorways in England: 13%
CONTROLLED MOTORWAY
Controlled motorways have three or more lanes with variable speed limits, but retains a hard shoulder. The hard shoulder should only be used in a genuine emergency.
These variable speed limits are displayed on overhead gantry signs - if no speed limit is displayed the national speed limit is in place. Speed cameras are used to enforce these.
Miles in total: 140.2 miles
Percentage of smart motorways in England: 31.0%
Percentage of all motorways in England: 7.3%
DYNAMIC HARD SHOULDER (DHS)
Originally referred to as Hard Shoulder Running smart motorways, dynamic hard shoulder running involves open the hard shoulder as a running lane to traffic at busy periods to ease congestion.
On these stretches a solid white line differentiates the hard shoulder from the normal carriageway. Overhead signs on gantries indicate whether or not the hard shoulder is open to traffic.
The hard shoulder must not be used if the signs over it are blank or display a red X, except in the case of an emergency.
A red X on the gantry above means you must exit the lane as soon as possible.
Overhead gantries on these types of motorway also display the mandatory speed limit which varies depending on the traffic conditions. Speed cameras are used to enforce these - no speed limit displayed indicates the national speed limit is in place.
