The UK government anticipates significant border delays at the end of the Brexit transition period, with a high percentage of hauliers potentially lacking the necessary paperwork for customs. This could lead to severe traffic congestion in Kent, affecting the flow of goods and causing economic disruptions. Measures such as an IT system for paperwork and fines for unprepared hauliers are being proposed to mitigate the impact. The government expects the disruption to ease by mid-2021 but is prepared to maintain measures for up to 11 months if necessary.
