How to build snow plow routes

In snow, the clock is the enemy. A route that's clever on a map but slow in a storm means a hospital lot isn't clear at shift change. Here's how to sequence a plow route that hits the important accounts first and finishes before rush hour.

A routing guide for snow removal operators.

Lawn routing is about saving money on drive time. Snow routing is about that and beating a deadline under brutal conditions, with liability on the line if a commercial lot isn't cleared when it opens. Two principles run the whole thing: priority and density.

Priority comes first

Unlike mowing, snow accounts aren't equal. Some have to be clear by a hard time or someone gets hurt — or sues. Rank every account before the season:

• Tier 1 — critical/high-liability: medical, elder care, businesses opening early, steep or high-traffic lots. These get cleared first, every event.
• Tier 2 — standard commercial and priority residential (contracts with tight response windows).
• Tier 3 — general residential, where a couple of hours' flexibility is fine.

Your route is a compromise between hitting Tier 1 fast and driving efficiently — but when they conflict, priority wins. That's the opposite of a lawn route, where you optimize purely for distance.

Then build density within priority

Inside each tier, the same rule as any route applies: tight beats scattered. Group accounts into zones so a truck works one area at a time instead of crisscrossing town at 3 a.m. Density is why you should price in drive time and think hard before taking a lone account 20 minutes outside your cluster — in a storm, that outlier can cost you a whole Tier-1 deadline.

Sequence to beat the clock

1. Start at the Tier-1 accounts nearest your shop or salt supply.
2. Work each zone as a loop that never doubles back.
3. Slot Tier-2 and Tier-3 stops into the geography between Tier-1 clusters.
4. End the route near your salt reload or shop so you're staged for a second pass.

Plan for the storm's realities

• Multiple passes. A long storm means re-running Tier-1 before Tier-3 is done the first time. Build the route so you can loop back without chaos.
• Access notes travel with the stop — gate codes, where to stack snow, "don't block the dumpster" — so a fill-in driver isn't guessing at 4 a.m.
• Proof of service. Time-stamped photos at each stop protect you on "you never came" disputes and are gold on commercial contracts.

Measure and tighten

After each event, look at how long the route actually took and where it bogged down. A route board that logs when each stop was cleared shows you which accounts to move zones, which outliers to drop, and whether you need another truck before you overpromise on response times in next year's contracts.
