They can't touch your license.
I'll tell you whats even more or a farce.
I live in Northern Ireland - part of the UK, and we have UK driving licenses.
A colleague of mine was caught speeding last year on the way to our Welsh office.
He got a letter requesting his license etc.
He sent this off with a payment for the fine and the license was returned stating that because it was issued in Northern Ireland they couldn't endorse it.
