Meanwhile, looking forward rather than debating the past of dictionaries, the Guardian is reporting this:

===============================

In the first of a series of steps to deal with the possibility of failing to reach a deal with the EU, the UK is signing up to a United Nations convention on road traffic, which theoretically also affects zebra crossings and parking.

The 1968 Vienna convention, which Britain previously avoided joining because it was too burdensome, has become an urgent necessity because the EU will no longer recognise UK-issued licences after Brexit and could ban all drivers and vehicles without an alternative agreement.
...
Insiders say the prospect of triggering this wave of extra red tape had led to furious rows within Whitehall but the lack of alternatives has forced proposed legislation – the haulage permits and trailer registration bill – to be rushed into the Lords.
...
But the biggest long-term challenge for the UK freight industry is the tiny number of travel permits potentially available for British truck drivers if there is no other solution found through an EU trade deal.

Under existing international treaties there are between 103 and 1,224 permits a year available to deal with more than 300,000 journeys by 75,000 British trucks.
===============================

This would only come into play in a 'no deal' scenario, but we all know that is better than a bad deal, don't we?
