Measures to manage traffic flow on Kent’s road network in the event of severe disruption to services across the English Channel.
Operation Stack is a procedure that uses parts of the M20 to queue lorries travelling towards the continent, to avoid causing gridlock across Kent’s roads.
It is used in emergency situations when crossings to the continent cannot happen, such as bad weather or industrial action.
Operation Brock is a traffic management system designed to keep Kent’s roads open if there is disruption at the Port of Dover and Eurotunnel.
When Operation Brock is in force HGVs travelling to Port of Dover and Eurotunnel must use the signed routes only. Enforcement officials will be deployed to intercept vehicles trying to use alternative routes. Drivers who are caught will be turned around and risk a £300 fine.
Signs, diversions, and speed restrictions will be in place to help drivers reach designated holding areas.
Kent Police take decisions on when to use the different phases of the system, depending on the scale of any disruption. Options include:
A20 Dover TAP
A queuing system which holds lorries until space becomes available at the port.
M20 moveable barrier
A concrete barrier than can be deployed quickly between junctions 8 and 9 of the M20 to install a contraflow. HGVs bound for Dover and/or Eurotunnel will be held on the coastbound carriageway.
An off-road site designed to hold traffic heading for the Port of Dover. Border readiness checks will take place here to ensure hauliers have the correct paperwork.
Ashford Sevington inland border facility
An off-road site next to junction 10A of the M20, likely to be used if the M20 contraflow approaches capacity.
Drivers travelling through Kent should be aware that there is potential for disruption in the event of delays at the border.
Plan your journey to ensure you take breaks and overnight rest periods before entering Kent. This will minimise the risk of hitting drivers’ hours limits.
Find out about motorway service areas along your route.
Make sure you have enough food and water in case of delays at the border. Welfare will be available for drivers stuck in stationary queues for extended periods of time.
If required, there is a pre-agreed plan to relax drivers’ hours to assist with congestion.
Check an HGV is ready to cross the border
HGV drivers no longer need a Kent Access Permit (KAP) to enter Kent.
The Check an HGV is ready to cross the border service has closed. Staff at haulier advice sites can help drivers check that they have the paperwork needed to cross the border.
