Does this sign prohibit you from entering the rail switch until it is unblocked?

Correct answer
NO
Explanation
In the photo, you can see a white board with a red border and a black letter "B", which is the sign BT-3 "points lock". This sign does not prohibit you from entering the points until they are unblocked - the answer is NO.
The sign BT-3 means that the tram driver must not drive under the device that controls the points until the previous tram has left the points. So the ban concerns driving under the control device, not entering the points themselves, and it ends when the previous tram leaves the points, not after some separate unblocking. The purpose is that the points must not be switched under the previous tram. You wait until the rear of the previous tram has passed the points.
