The consequence is 2 vehicles crawling side by side for mile after mile until something eventually happens. This may mean that the outer lorry finds an extra mile an hour and after perhaps 4
minutes completes the futile exercise.

Extremely rare is the situation when the driver recognises and accepts the mistake before pulling over.
This is serious business - queues of a mile or more of traffic can find themselves backed up.
I have never heard of a prosecution for this and it really must fall under several statutes. Come on you motorway cops - clear the M18 at the very least!
