The gritters from the municipality of Utrecht will leave at 6 p.m., but it is not yet known when they will return. “Now the expectation is that they will drive two laps, then it will be about 11 p.m..” And what happens then? “If it stops snowing, and the road is still damp and the temperature is below zero, we will have to drive another lap to prevent slippery conditions,” Schaap explains. The question remains when Schaap’s working day ends. “You actually never know when you’re ready. Sometimes that’s difficult, but you also learn to switch quickly.”
