This research into the use of red flashing lamps on recovery vehicles in Great Britain was conducted in 2 phases.

The first phase focused on reviewing existing evidence and any new research or information on red flashing lamps.

The second phase covered:

• the development of a 'best practice' guidance document on the use of vehicle warning lamps
• assessment of the likely risks associated with the proliferation of warning lamps
• off-road trials of rear-facing red flashing lamps on recovery vehicles

The research was carried out by TRL Limited on behalf of the Department for Transport. The findings will be used to develop future policy to support a decision on whether to extend the permitted use of red flashing lamps to roadside rescue and recovery vehicles.
