Question to the Department for Transport:
To ask the Secretary of State for Transport, how many accidents there have been on Smart motorways as a result of a change in the use of lanes in each of the last three years.
It is not possible to provide data on the number of accidents on Smart motorways as a result of a change in use of lanes, as we cannot determine that as the cause.
Data is collected on factors that contribute to how and why personal injury road accidents occur. However, it is not possible to attribute the cause of an accident to the presence or absence of Smart motorways operation.
