The Department’s review of the safety of Smart Motorways across England, published in March 2020, showed that overall, the evidence shows that in most ways, smart motorways are as safe as, or safer than, the conventional ones. But not in every way. To ensure we are doing all we can do to improve safety, a package of 18 measures were published in March. This will allow us to retain the benefits of smart motorways while addressing the concerns that have been identified.
