Q: Wiki gives us the following explanation of the use of high beams in a car:

Main-beam (also called high, driving, or full beam) headlamps provide an intense, centre-weighted distribution of light with no particular control of glare. Therefore, they are only suitable for use when alone on the road, as the glare they produce will dazzle other drivers.

But what if you drive at night on a fully separated highway, such as the Autobahn? Are you allowed to turn on the high beams? I assume the middle barrier will prevent other drivers from getting blinded, but perhaps it would also be annoying to the drivers in the front?

A:
Is it legal to turn high beams on when driving on a European highway with fully separated lanes?
