To sort the trucking shortage, the British Government is easing the cabotage rules. Instead of the two allowed cabotage jobs, foreign drivers will be allowed to do unlimited cabotage jobs in a period of 2 weeks.
According to the BBC, British Government can implement this system before Christmas for a period of minimal 6 months.
The system will be set up after the failed attempt of British Government to attract foreign drivers with work visas. Just a hand full of drivers applied for this, meaning that the majority of the 5,000 visas will not be used.
Below links from BBC and GOV.UK will give you full information on this subject.
