The pickup truck rolled down the north Minneapolis street on Tuesday at a slow, ominous speed, an orange signal light flickering above the cabin.
The men inside, inspectors for the city of Minneapolis, had one mission: to check whether residents had shoveled their sidewalks.
It was the fourth round of inspections since the city announced last year it would crack down on people who failed to clear their sidewalks. It has been the responsibility of homeowners for decades, and the former method of compliance — neighbors telling on neighbors — wasn't working, officials said.
The inspections are one of several new strategies to keep nearly 2,000 miles of sidewalks clear for pedestrians during the winter. The city is also weighing whether it should shovel major corridors, as some suburbs do.
"Sidewalks are an incredibly important transportation system, if you think about it," said Lisa Cerney, the deputy director for the city's Department of Public Works. "Every trip starts and ends with walking."
Because there haven't been many significant snowstorms so far, inspectors had only gone out three other times.
Before Tuesday, they had examined about 13,000 parcels and found 689 violations, Cerney said. The compliance rate has been promising, with about 95 percent of households shoveling their sidewalks.
This week's storm brought down almost 5 inches of snow, according to the National Weather Service, leading the city to issue a snow emergency Monday. It also gave homeowners 24 hours to clear the sidewalk in front of their property.
