Question to the Department for Transport:

To ask the Secretary of State for Transport, what information his Department holds on how many collisions involving buses have been caused by driver fatigue in each year since 2010.

The Department does not routinely collect information on the causes of collisions involving buses.

The closest available information held in relation to road collisions are statistics on contributory factors. When police officers attend the scene of a collision, they are able to select up to 6 factors they believe contributed to the collision. These do not assign blame for the collision to any specific road user but gives an indication of which factors the attending officer thought contributed to the collision.

The number of reported personal injury road collisions involving bus drivers which were assigned the “fatigue” contributory factor by an attending police officer in Great Britain from 2010 to 2021 (the latest year for which figures are available) can be found in the table below.
