- Corridors
- Storm reports here use I-80 and I-78 as markers. ONJSC noted that only a bit of sleet made it north of the I-80 corridor in a mostly all-snow January 2026 storm, and that the January 2016 blizzard's highest totals fell between the I-78 and I-80 corridors. ONJSC recaps dated February 7, 2026 and February 6, 2016
- What we write here
- General liability that names plowing and salting, commercial auto for plow trucks, contractor's equipment for blades, spreaders and loaders, workers' compensation for the crew, umbrella limits, and contract and certificate review. Coverage depends on the policy's actual forms and endorsements.
Count the Events, Not Just the Inches
For a contractor, the figure that drives exposure is how many times the trucks roll out. The Sussex 3 WNW station averages 6.3 days a year with 2 inches or more of snow, and Pottersville 2 NNW averages 5.6 (NOAA 1991–2020 normals, both provisional). Each of those is a night of driving, a round of walks, a fresh layer of slip-and-fall exposure on every account, and more hours on every machine.
Two things follow. A contract that pays per push earns on volume, and the exposure grows with it: each visit is one more time stamp someone can ask about later. Keep the service log as carefully as the invoice.
The second is the audit. Workers' compensation is rated on payroll, and many contractor liability policies are rated on payroll or receipts, so both get trued up after the policy year. Winter 2025–26 ran 21.0 inches above normal in ONJSC's northern division (March 6, 2026 recap). A season like that pushes real payroll past the estimate, and the difference arrives as an audit bill in spring. If your crew roster grew in January, tell us in January.
Cold That Outlasts the Storm
The snow stops; the exposure keeps going. Walpack, in Sussex County, hit 17 degrees below zero on January 28, 2026 (ONJSC January 2026 recap, February 7, 2026). In cold like that, meltwater from your piles runs across drive lanes and freezes overnight, and salt works slowly. A walk you cleared at 5 a.m. can be glazed again by noon.
That is where the contract earns its keep, or doesn't. Read what you agreed to after the storm ends: re-checks, refreeze treatment, how fast you must answer a call. If the contract says you return for refreeze and your log shows no visit, that gap lands on you before it reaches any insurer.
In the highlands the storm is one night. The refreeze is the rest of the week.
Equipment lives in this weather too. A skid steer parked at a client's lot all winter belongs on a contractor's equipment schedule at a value that would actually replace it. A blade or spreader mounted on a truck needs a home on either the auto policy or the equipment form, and we check which one claims it before you need it.
One Region, Two Kinds of Book
Morris County holds 16,518 of the region's 21,988 business establishments (Census County Business Patterns 2023; the regional total is our sum). Those accounts often come with a property manager and a written contract asking for additional insured status, primary and non-contributory wording and a waiver of subrogation. Send us the insurance page before you sign.
Sussex and Warren run on a different scale, with 3,184 and 2,286 establishments (Census County Business Patterns 2023) spread over long drives. If your book out here is a pickup, a blade and a list of driveways and small lots, the truck is the first question. A plow truck titled to you and sitting on a personal auto policy is the gap we look for first; read our note on plow trucks on personal auto and see how we write owner-operators.
One more pattern to plan for: big coastal storms can miss the northwest. In the February 22–23, 2026 blizzard, ONJSC reported the top Warren County total was only 9.2 inches, in Hackettstown (March 6, 2026 recap), while Strathmore in Monmouth County measured 26.5 inches in the same storm (same recap). On a night like that you may be asked to send trucks south to help another contractor. Tell us first. The auto policy should know where the trucks go, and the other contractor's agreement will carry insurance requirements of its own; see working as a subcontractor.
Northwest Highlands Questions
Does a heavy winter change what I pay for insurance?
It can, at audit. Workers' compensation is rated on payroll, and many contractor liability policies are rated on payroll or receipts. When ONJSC's northern division ran 21.0 inches above normal in winter 2025–26 (March 6, 2026 recap), a season like that could mean more pushes, shifts and salt runs than the estimate assumed. A realistic estimate up front keeps the spring audit from becoming a surprise.
I plow driveways in Sussex with my own pickup. Is my personal auto policy enough?
Once customers pay you, probably not. Plowing for hire is a business use, and the carrier on a personal policy has to know about it. We start with three facts: whose name is on the title, who else drives the truck, and what's bolted to the front of it. The answers decide where the truck belongs. Our guide to plow trucks on personal auto goes further.
My skid steer stays at a client's lot in Morris all winter. Is it covered there?
It can be, if it's scheduled on a contractor's equipment policy whose form covers it at that location. Compare the scheduled value with what a replacement would cost today, and check how the form treats theft from an unattended site. Coverage depends on the policy's actual forms and endorsements, so send the schedule and we'll read it with you.
My trucks sometimes work storms outside the northwest. Does that matter?
Yes. We're licensed in all 21 New Jersey counties, so the work itself isn't a problem, but your auto and liability policies should reflect where the trucks actually operate. Give us every county you plow in, including nights you help another contractor.
