MnDOT Urges Caution At Snow-Covered Intersections

MINNESOTA — The Minnesota Department of Transportation urges the public to use extra caution when approaching traffic signals following a heavy snowfall event. Motorists and pedestrians should be prepared to stop at intersections with traffic signals, as snow-covered traffic indications can be challenging to see.

For reasons of energy efficiency and longer service life, the state’s traffic signals have switched from using incandescent bulbs to light-emitting diodes, according to a news release. LEDs produce less than half the heat as incandescent bulbs, and do not emit enough heat to melt off snow and ice that may accumulate on them.

"Following a snow event, our top priority is clearing roads for the traveling public. Once complete, city, county, and state maintenance crews address other key areas," said MnDOT District Traffic Engineer Scott Thompson in a statement.

"We urge motorists to come to a complete stop before going through intersections with snow-covered traffic signals. It’s the safest solution until city and county crews can clear them."
