Perhaps you are from NL, Denmark, Germany or Sweden. Traffic management in Italy, Belgium, France, Spain, Portugal, Romania, Greece is insane (and you can't even take a right when it's red!)
You can't anywhere in continental Europe it seems.
Not generally allowed, but there are signs allowing it almost everywhere.
Maybe 50% or less where I live. Never counted but certainly not even close to "almost everywhere"
The Grünpfeil (green arrow) traffic sign that allows right turns through a red light was actually invented in the GDR, so it's more common in East Germany.
