You are driving a tram. What should you do when approaching a puddle located on the trackway?

The question is about driving a tram through a puddle on the tram tracks. You should drive through at the lowest possible speed - answer B.

The water covers the rails and the tram tracks, so you cannot see whether there is damage to the track, stones in the rail grooves or another obstacle under the water. Driving through fast (answer A) splashes water onto pedestrians and cars and makes it harder to react to a hidden obstacle. Stopping before every puddle (answer C) is not necessary and makes traffic harder for no reason - stopping is advisable only when water floods the rails over a long section. After driving through a puddle, remember that wet wheels and rails make the braking distance longer.
