This traffic light allows you to go 
Under clause 14, a traffic light with white-lunar signals arranged in a T shape controls the traffic of trams and of route vehicles travelling on a dedicated lane. Movement is allowed only when the lower signal is on, and the upper signals that are on show the allowed directions: the left one to the left, the middle one straight, and the right one to the right. In this case the lower, the upper middle and the upper right signals are on, allowing movement straight and to the right. Only the upper left signal is off, which means that movement is prohibited only to the left.
Option 2. Going straight is allowed, because the upper middle signal is on.
Option 3. Going straight and to the right is allowed by the signals that are on, not prohibited.
Option 4. A right turn is allowed, because the upper right signal is on.
