Question

From belfast to stranraer for example, do you just drive onto the ferry, or stopped and asked for ID?

Answer 1

In theory you shouldn't need any identification because you are travelling within the United Kingdom. A driving licence ought to be sufficient should anyone ask for some ID.

Answer 2

THe UK and Ireland are a so-called "common travel zone", and no ID is required normally. If you are driving you need your licence anyway.

But neither country has joined the Schengen agreement, so you need a passport to get to the Continent.
