As the Sun explains it:
An example of a route affected is Western Greyhound's Newquay to Plymouth service, which now involves three buses and requires passengers to buy three separate tickets, but uses only one driver throughout.
A Brussels ruling has banned local services longer than 30 miles to ensure drivers don’t spend too long at the wheel.
As a result, drivers have to pull in as they hit that limit and order everyone OFF their bus.
They then change the route number on the front and invite passengers to jump back ON before resuming the trip.
The Sun report goes on:
An opt-out would be welcome, but why are local bus routes a matter for the EU in the first place?
Last night Lib Dem transport spokesman Norman Baker blasted the “lunatic law”.
He said: “These rules don’t stop buses running more than 30 miles.
“All they do is inconvenience the passengers who have to keep getting on and off. It’s like an Ealing comedy.”
He has written to Transport Secretary Ruth Kelly demanding an opt-out.
