Details

Research evaluating the impact of the operation of longer semi-trailers (LSTs) on Great Britain’s roads.

The trial is designed to evaluate the impact of LST operations on:

  • efficiency
  • emissions
  • safety

and whether the expected reduction in emissions, due to less journeys, is realised without detrimental effect.

The research was commissioned by Department for Transport and trials originally started in January 2012.
