Does the signal mean that in a while the red signal comes on?

In the photo, directional traffic lights S-3 with left arrows, showing red and amber at the same time. The signal shown does not mean that the red signal will come on in a moment. The answer is: no.

The Regulation on road signs and signals states - and this applies accordingly to directional traffic lights S-3 - that red and amber signals shown together mean that you must not go beyond the traffic lights and announce that the green signal will come on in a moment; red, on the other hand, is announced by the amber signal alone, shown after green. The sequence is always the same: red, red with amber, green, amber, red - so after red with amber, red cannot come on, because it is already lit. Confusing these signals has practical consequences: a driver who expects more red after red with amber will move off late and block traffic, and a driver who expects green after amber alone will enter on red. A simple way to remember: amber together with red means "get ready to go", amber alone means "get ready to stop".

Legal basis: § 97 para. 2 in conjunction with § 95 para. 1 point 2 and 4 of the Regulation on road signs and signals
