Smart Motorways

Lord Harries of Pentregarth Excerpts

Wednesday 11th February 2026 Lords Chamber

Asked by

[Lord Harries of Pentregarth]

To ask His Majesty’s Government what assessment they have made of the post opening project evaluations of smart motorways in relation to (1) safety, and (2) value for money.

[Baroness in Waiting/Government Whip (Baroness Blake of Leeds) (Lab)]

My Lords, I thank the noble and right reverend Lord, Lord Harries of Pentregarth, for his Question. I assure him that safety is our top priority. While National Highways reports show that smart motorways are meeting or exceeding safety objectives in all but one upgrade, we know that people need to feel safe as well as be safe. That is why National Highways invested some £900 million to improve safety and educate drivers. The reports show that these upgrades have added vital capacity to some of the country’s busiest roads and are largely on course to meet their environmental goals.

[Lord Harries of Pentregarth (CB)]

My Lords, I thank the Minister for her reply, but according to National Highways’ official reports, these big projects to convert hard shoulders on the M1, M4, M6 and M25 were regarded as poor, or very poor, value. I wonder whether the Government agree with that assessment. My main concern, however, is safety. Although I totally respect the huge improvements made by the technology—the electronic signs that can control traffic and close lanes—it has nevertheless been shown that casualties and serious injuries have gone up on some stretches of these smart motorways: the M3 and parts of M1, for example. Therefore, what further steps will the Government take to improve safety on these smart motorways?

[Baroness Blake of Leeds (Lab)]

Just to broaden the issue, the majority of schemes are delivering economic benefits and have created additional lane capacity, which is beneficial now and into the future. I think it goes back to the perception issue. Smart motorways remain our safest roads, and we are monitoring the impact of investment in safety, including the 150 emergency areas we have added. I hope that answers some of the noble and right reverend Lord’s questions. Although carrying half the traffic, 327 more people were killed or seriously injured on A-roads compared with motorways. We take road safety seriously, and recently published our new road safety strategy, in which we outline the further measures we are intending to take.
