M20 Operation Brock contraflow in operation

Operation Brock is part of a series of measures to make sure traffic flows smoothly when cross-channel services are disrupted.

While the contraflow is in operation

Please follow all signs and directions.

HGVs

When Operation Brock is in force, HGVs are legally required to use the signed routes for journeys to Port of Dover and Eurotunnel.

If you're an HGV driver heading for the Port of Dover or Eurotunnel, you must follow signs to join Operation Brock at M20 junction 8.

You risk incurring a £300 fine if you:

• don't obey signs
• try to use other routes to Eurotunnel or the Port of Dover (including trying to bypass the M20 by using the M2/A2 at Brenley Corner)

You'll also waste your time, fuel and money as police or enforcement agents will send you to the back of the queue.

Other coast bound traffic (including local freight and car drivers heading for the continent)

All other coast bound traffic should follow signs and cross over to enter the contraflow on the M20 London bound carriageway.

Plan ahead

If you intend to use Eurotunnel and the Port of Dover, plan your journey and check with your travel operator before setting off.

Allow more time for your journey and make sure you're prepared for delays. Have plenty of fuel and supplies such as food and cold drinks.

Follow our advice for driving in hot weather.
