The Secretary of State for Transport has recently received a letter and report from Campaign for Better Transport following their attendance at a demonstration of a longer semi-trailer in June. The report has made very broad assumptions based on a single demonstration of a longer semi-trailer that was not representative. The report has called for longer semi-trailers to be allowed only on designated local authority roads and we anticipate responding to the report's authors shortly. The Government will continue to monitor the trial closely and will report in full when the trial concludes at which point Ministers will decide whether these vehicles will be allowed permanently on UK roads.
