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.
Kent Police are responsible for implementing Operation Stack.
