Operation Brock

Last updated: 13 November 2019

Operation Brock is currently: Inactive

What is Operation Brock?

Operation Brock is designed to keep the M20 open in both directions between junctions 8 and 9 in the event of disruption to services across the English Channel, whatever the cause. Operation Brock is an alternative to the older Operation Stack, and offers significant improvements by keeping the M20 open to traffic in both directions.

How should I prepare for Operation Brock?

If you are travelling in Kent while Operation Brock is active you should allow more time for your journeys. It’s also a good idea to make sure you take some food and water in your vehicle in case you are delayed.

How does Operation Brock work?

Operation Brock is currently inactive. However, the situation will be kept under review and is subject to change.

When Brock is inactive, the M20 will operate as follows:

  • All traffic heading coast-bound will be able to use the three-lane coast-bound carriageway. The national speed limit applies unless signed otherwise.
  • All London-bound traffic will use the hard shoulder and lane 1 on the London-bound carriageway. The speed limit will be 50mph. Average speed cameras will remain in operation.

When Brock is active, the M20 will be operational as follows:

Cars, coaches and goods vehicles under 7.5 tonnes

All cars, coaches and goods vehicles under 7.5 tonnes heading coast-bound will follow signs on the M20 through the two-lane contraflow irrespective of their destination (local or heading towards the ports). Drivers leaving the UK should check conditions before setting out and, if they’re crossing the channel, check with their service operator for updates and ensure they have all the required paperwork.

HGVs over 7.5 tonnes heading coast-bound to leave the UK

All HGVs over 7.5 tonnes heading coast-bound to leave the UK will follow signs on the M20 approaching junction 8 and 9 and get in the correct lane of the coast-bound carriageway per their port-destination. Such HGVs will be subject to paperwork compliancy checks and will be stopped for verification checks by an official at dedicated checkpoints. Details of the paperwork they need to produce are available through the Department for Transport website.

Compliant HGVs exiting the UK

It is important all paperwork associated with the goods in your vehicle is up to date. HGVs having the correct paperwork in place will be deemed authorised to progress to their destined port after the necessary check by an official. Drivers will be provided with check confirmation paperwork to present at the ports to be authorised to progress with their further journey across the channel.

Non-compliant HGVs wishing to exit the UK

If your paperwork is not correct you may be asked to divert to a holding area at Ashford or Manston where you will get advice on how to get border ready. Failure to comply with instructions may result in fines and further delays.

Phase 1 – In the event of excessive disruption to services across the English Channel, improved holding capacity at Port of Dover and Eurotunnel, as well as the activation of DoverTAP (queue management of port destined HGVs on the A20 approach to Port of Dover) will be used.

Phase 2 – If phase 1 capacity is reached, we will start queuing Europe bound HGVs over 7.5 tonnes on the coast bound section of the M20 between junction 8 and 9. All other vehicles will be signed to use the contraflow.

Phase 3 – If phase 2 becomes full, lorries heading for Port of Dover will be directed to Manston Airfield, while the M20 will be used to hold Eurotunnel destined HGVs only. Traffic lights on the A256 after Manston Airfield will help to manage traffic arriving at the Port of Dover.

Phase 4 – If the M20 holding area becomes full, the M26 will be used to hold additional lorries wishing to leave the UK via Eurotunnel. When held on the M26, you’ll be held until space on the M20 junction 8-9 becomes available.


Drivers of goods vehicles over 7.5 tonnes

Drivers of vehicles of 7.5 tonnes or more leaving the UK and heading towards mainland Europe via Port of Dover or Eurotunnel need to follow queuing arrangements. Regardless of your end destination, check conditions before setting out, follow all signs and signals and ensure you have the required paperwork.

Instructions for drivers will be clearly signed, actively managed and monitored at every step. If you don’t follow the instructions you may be stopped, redirected to re-join the appropriate route and delayed, and may incur a fine.

The holding areas are all temporary and will be stood down as soon as they are no longer needed. These areas will be safe and have access for emergency services. Manston Airfield will be secure and have water, toilets, showers and rubbish bins.

Information for what is needed for HGVs/Hauliers traveling to mainland Europe is available to view and translated versions are available at the bottom of the page


Phase 1

Use any available major route. If you use the M20, use the left-hand lane of the M20 between junctions 8 and 9. The speed limit will be 30mph.

Maidstone Roadchef services at junction 8 are open as normal however there will be no direct access back onto the M20 coast-bound at junction 8. To join the coastbound carriageway please travel London bound to junction 7 and turnaround, this will add about five minutes to your usual journey on the M20.

Phase 2

Use the M20 and observe signs approaching the M20 junction 8 and get in lane. Use the left-hand lane of the M20 between junctions 8 and 9. You will be held until space at the Eurotunnel becomes available. The speed limit will be 30mph.
