Asks if we should stop the longer semi-trailer trial ahead of schedule.

Detail
Consultation asking if we should end the existing longer semi-trailer trial (LST). The trial, which started in 2012, is testing the theory that the use of LSTs should lead to journey reductions, which in turn would lead to a reduction in transport:
- congestion
- emissions
Although planned to run until 2027, we believe the trial has reached a point where continuing is unlikely to provide useful results and that remaining issues, relating to the safety, can only be answered outside of trial settings.
