Of the beacons shown in the image, which one specifically indicates the 'proximity' of a level crossing, movable bridge, or quay?

Question

DentroTest · Accepted Answer

The correct answer is These signs are beacons (P-9a, P-9b, P-9c) that perform a visual 'countdown' to warn of the arrival at the danger zone:   Option 1 (Correct): The beacon with three red stripes (P-9a) indicates Proximity. It is the first sign you encounter and marks the beginning of the danger zone.   Option 2: The beacon with two stripes (P-9b) indicates Approach (you are halfway there).   Option 3: The beacon with one stripe (P-9c) indicates Closeness/Vicinity (you are very close to the danger). Mnemonic: Remember the 3-2-1 countdown (3 stripes = first sign = Proximity).
