Quantum physicists say they’ve discovered a third state of the Mountain Road which is both open and closed.

Previously, traditional science had predicted the route from Ramsey to Douglas could only be one or the other.

But boffins at the Department of Infrastructure say it can now be closed between Ramsey Hairpin and the Creg ny Baa and still have traffic on it.

They say the phenomenon happens when halfwits ignore very clear ‘road closed’ signs and drive onto the route anyway.
