Question to the Department for Transport:

To ask His Majesty's Government how many people were killed in collisions where the driver was under the influence of drugs in (1) 2019, (2) 2020, (3) 2021, (4) 2022, (5) 2023, and (6) 2024.

Data on road injury collisions are reported by police using the STATS19 system. Police officers who attend the scene can assign factors to a driver if they believe that they may have contributed to the collision occurring.

The number of fatalities from collisions where the road safety factor “affected by drugs” was assigned to the driver of a motor vehicle for the years 2019 to 2023 are shown in the table below.

Data for 2024 will be published in September 2025.
