Question to the Department for Transport:

To ask the Secretary of State for Transport, how many serious vehicle accidents have resulted from potholes in (a) Hertsmere constituency and (b) Hertfordshire since 2015.

The Department’s reported road collision statistics do not identify the cause of collisions. However, reporting police officers can assign up to 6 road safety factors which they believe may have contributed to the collision occurring.

The number of collisions, involving at least one seriously injured casualty, which were assigned road safety factor “poor or defective road surface or deposits on road” between 2015 and 2024 are shown in the table.
