Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what is the maximum duration that Army or MoD crews undertaking User Validation Trials are allowed to remain in the vehicles, on any Ajax family vehicle.

In addition to extant Army wide driver and crew working hours controls, trial activity duration is not time bound but is carefully monitored to ensure that Army crews remain within the lower action values of the Control of Noise at Work Regulations 2005 and the Control of Vibration at Work Regulations 2005 throughout the planned activity. User Validation Trials are conducted under a safe system of work that implements these action value controls endorsed by the Safety Assurance Panel. This includes UTAC-Millbrook providing live monitoring of crew noise and vibration exposure levels.

Army crews are not required to undertake neurological tests as part of the trial protocol.
