Does this sign inform you of a significant longitudinal drop in the tram track by the value given on the sign?
Show the correct answer
Correct answer
YES
Explanation
In the photo, you can see a white square board with the number "25‰" and a black area sloping down from left to right, which is the sign AT-3 "dangerous descent". This sign warns about a significant downward gradient of the tram track of the value shown on the sign - the answer is YES.
The value of 25 per mille means that the ground drops by 25 m over every 1000 m of track. AT signs are additional warning signs for tram drivers. They are placed on the right-hand side of the track, above the track or between the tracks on the poles of the overhead contact line, 50 to 200 m from the dangerous place, and they oblige the tram driver travelling on that track to exercise particular caution. On a descent, the tram speeds up by itself and the braking distance gets longer, so you go down slowly and brake earlier.
