Derbyshire police have joined forces with their colleagues in Leicestershire and Nottinghamshire to form the East Midlands Serious Collision Investigation Unit.
The new unit will investigate collisions which result in serious injury or death across all three counties.
Assistant Chief Constable Steph Morgan, of Leicestershire Police, said: “The principle of collaboration is that local policing should be delivered by local forces, working together to increase resilience and improve performance.
“We will be taking the very best of what the individual units have already provided very effectively for many years, and enhancing that level of service even further through collaboration.
“This collaboration will ensure that senior investigating officers in the three forces will always be able to assign sufficient resources to the scene of a serious collision wherever and whenever it occurs in Derbyshire, Leicestershire or Nottinghamshire. That will mean officers and investigators crossing county borders to carry out or assist with investigations as and when required.”
The formation of the regional unit aims to achieve: standardisation in investigation and processes; increased resilience; most effective use of new technology, such as laser scanning; pooling expertise in the field of collision investigation and vehicle examination and consistency of service.
Latest figures show that in 2012, 25 people were killed and 390 seriously injured in crashes in Derbyshire.
ACC Morgan added: “Between the three counties there are around 9,000 miles of roads to police, including a 70-mile stretch of the M1, which courses through all three counties, and a very busy section of the A1, not to mention other key A-roads.
“Thousands of vehicle journeys are made each day on those roads, the vast majority in complete safety. But when there is a serious collision we need to be able to have the resources available to ensure that the investigation we carry out determines the exact cause.
“Ultimately, we are all aiming reduce the number of people who are killed or seriously injured as a result of collisions on our roads.”
