When activated, vehicles can use the hard shoulder as a running lane. All lanes are limited to a maximum of 60 mph, but these can be lowered further. In October 2019, the chief executive of Highways England told MPs that the company has no plans to introduce the configuration to any further section of motorway, after admitting that motorists found the setup 'too confusing' to use. A study conducted in the previous month found that more than half of motorists surveyed would not drive on a hard shoulder even if it was open. A stocktake taken in March 2021 confirmed that all DHSR smart motorways will end the use of them by March 2025 by converting all current DHSR to ALR.
