Clocks go back this weekend — the hazards that come with it start now

Daylight saving time ends in the early hours of Sunday, November 1. Clocks go back an hour. For anyone working the overnight, that is an extra hour on the board. For everyone else it means the evening commute now runs in the dark, and darkness plus wet leaves plus the first hard frosts is the mix that fills the first two weeks of November every year.

Heating season is the one worth flagging first. As homes switch furnaces and space heaters back on, carbon monoxide calls climb. Treat the vague, multi-occupant complaint — headache, nausea, everyone in the house feels off — as CO until a meter says otherwise, and remember the meter protects you before it diagnoses the patient. Unflued heaters, generators run in garages, and blocked flues are the usual sources.

Road surface is the other predictable one. Overnight temperatures are now dropping to or below freezing in many areas while daytime roads stay wet. That produces black ice on bridges and shaded curves before it shows anywhere else, often while the open road still looks clear. Leaf cover hides it and cuts traction on its own. Expect more single-vehicle run-offs and more secondary collisions at crash scenes. Park to protect the scene and assume the next vehicle has not seen you.

Shorter days change the pedestrian picture too. More people are now walking, waiting and standing in the roadway in the dark during peak traffic. Visibility works against everyone.

None of this is new to you. The point is timing: the change happens on one weekend, and the call volume that follows is consistent year to year. Check your own CO monitor and its battery, confirm your scene lighting works, and factor the lost hour into fatigue if you are riding the overnight into Sunday. If a severe-weather or cold-snap warning is issued for your area, work from your own agency's forecast and advisories rather than a general outlook.
