Roads: Accidents

Question: To ask the Secretary of State for Transport, how many serious vehicle accidents have resulted from potholes in (a) South Holland and the Deepings constituency and (b) Lincolnshire in each year since 2015.

Answer

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.

There were no fatalities between 2015 and 2023 (the latest year for which figures are available) in collisions assigned the road safety factor “Poor or defective road surface or deposits on road” in South Holland and the Deepings.

Fatalities for Lincolnshire are shown in the table.

Lincolnshire	0	0	1	0	0	0	2	0	2

All fatalities were drivers or riders.

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 2023 are shown in the table.
