Seasonal snow-only policies: real, or a trap?

The honest answer is that they’re real, they’re rare, and whether the one in front of you is a trap comes down to three things you can read on the form in ten minutes. A seasonal snow-only policy is a general liability policy written for part of a year, usually November through April, limited to snow and ice operations. A few carriers write them. For a narrow kind of operator they’re the right fit. For everyone else they cost more than they look and leave more uncovered than they say. We run snow removal insurance for plow operators across Colorado and push snow above 9,000 feet ourselves, so here’s how to read one before you sign it.

What a seasonal snow policy actually is

Two things to keep separate. The policy period, and the operations it covers.

The policy period is the calendar. An annual GL runs twelve months from the effective date. A seasonal one runs for the months you plow, and the certificate you hand a property manager shows that expiration date on its face. The operations are the classification: snow and ice removal, and nothing else. No landscaping, no hauling, no hardscape in the spring. If it’s not snow, it’s not on the policy.

Who it fits: the operator whose entire business is pushing snow. The person with a day job and a three-quarter-ton with a Boss blade who runs forty driveways in Breckenridge and Frisco from Thanksgiving to April and does nothing else for pay. That operator has no summer exposure to cover, and a seasonal policy matches the season. It’s a real product for a real person. The trouble starts when a landscaper buys one.

Trap one: the minimum premium

Carriers generally set a floor for what a policy costs, no matter how short the term. The concept is called a minimum premium, and it exists because issuing a policy, underwriting it, and reserving for it costs the carrier about the same whether it runs five months or twelve.

What that means in practice: a five-month policy is not priced as five-twelfths of an annual one. It’s priced from the floor up. The direction is that seasonal costs more per month of coverage than annual, and for a small route the gap between a seasonal snow policy and a full-year GL with snow rated on it can be narrow. We won’t put a figure on that, because there isn’t one that’s true for every operation. The point is that “seasonal” reads like “cheaper” and often isn’t.

There’s a second version of the same trap. Some operators buy an annual policy and cancel it in April to save the summer months. Most policies cancel short-rate, meaning the carrier keeps a penalty on top of the earned premium, and a cancellation history follows you to the next application. Ask before you do it.

Trap two: the tail after April

This is the one that costs money. A slip-and-fall on a lot you plowed doesn’t arrive in February. It arrives as a letter in July or August, months after the seasonal policy expired, and the slip-and-fall article covers how slowly that unfolds. What happens next depends entirely on the form’s trigger.

Under an occurrence form, the policy that was in force on the day of the fall is the policy that typically responds, even though it has since expired. The August letter goes to the carrier that wrote the November-to-April policy, and the expiration date doesn’t matter. That’s how most standard GL forms work, and it’s why an occurrence-form seasonal policy can be a legitimate product.

Under a claims-made form, the claim commonly has to be made against you and reported to the carrier while the policy is in force, or during an extended reporting period you bought. A seasonal claims-made policy that ended in April and a letter that arrives in August is the trap in its purest form: the fall happened during the policy, the report didn’t, and under most claims-made wording nobody owes a defense. Short-term policies are sometimes written that way. Read the trigger. If the dec page says claims-made, ask what the extended reporting period costs and how long it runs, and read the answer as part of the price.

There’s a paperwork version too. A national management firm or an HOA board that requires a certificate showing coverage in force through the contract term will read an April expiration date as a gap, and some contracts require you to keep the same coverage for a period after the work ends. The national subcontract article walks that exhibit; the seasonal policy doesn’t always satisfy it.

Trap three: the other eight months

A seasonal snow-only policy covers snow. If you do anything else for money between May and October, the summer is uncovered. That’s the landscape-in-summer, plow-in-winter gap run backwards: instead of a landscaping policy that never heard about the plow route, it’s a plow policy that never heard about the mowers.

And even in winter, the seasonal GL solves one line of four. The truck sliding into a stopped car on Hoosier Pass in a whiteout is a commercial auto claim, and commercial auto is written annually with the plow disclosed; the plow truck article covers why the personal policy won’t carry it. The Yanmar mini skid steer with the pusher box is equipment, on its own schedule. And the driver you hire for the winter is an employee: Colorado employers must carry workers' compensation insurance as soon as they have one or more employees, whether part-time, full-time, or family members (C.R.S. 8-40-203(1)(b), 8-44-101); the state can fine an uninsured employer up to $500 for every day without coverage. (C.R.S. 8-40-203(1)(b); 8-44-101; 8-43-409) There is no seasonal carve-out in that statute. The workers’ compensation page covers the one-employee rule and the owner election.

What it doesn’t change: the contract

Whatever policy you carry, the HOA’s winter addendum and the management firm’s subcontract say what you owe. Colorado’s 2018 law narrows one piece of that. Colorado's Snow Removal Service Liability Limitation Act (C.R.S. 13-21-129, effective August 8, 2018) voids any snow-and-ice contract clause that requires one party to indemnify, hold harmless, or defend the other for the other party's own acts or omissions, but only where the service provider was prohibited, by the contract or in writing, from mitigating the specific snow or ice event at issue. (C.R.S. 13-21-129(3), (4); SB 18-062)

Plainly: it voids the part of an indemnity clause that makes you pay for the owner’s own act, only where the owner told you in writing not to treat the specific event. Everything else in the clause runs as written, and whether your GL picks up what you agreed to owe depends on the form’s contractual liability wording. A seasonal policy has to carry that wording just like an annual one. The indemnity law article has the whole statute, and the HOA contracts article covers where the clause shows up in a board’s template.

How to read the one you’re offered

Ten minutes with the quote before you say yes.

• Policy period. What are the exact dates, and do they cover the first storm and the last one? A Park County season doesn’t respect a November-to-April form; the wind off South Park drifts roads shut in October and May.
• Occurrence or claims-made. It’s on the dec page. If claims-made, what does the extended reporting period cost and how long does it run?
• Classification. Snow and ice removal, in words. If the classification says something else and snow is assumed, ask for it in writing.
• Contractual liability. Is it there, and is the indemnity clause in your HOA or subcontract something the form typically responds to?
• Additional insured and primary wording. Can the carrier endorse the association, the manager, and the national firm, or is that unavailable on the short form?
• Certificate date. Ask your biggest holder now whether an April expiration satisfies their contract term.
• Everything else. Truck, blade, pusher box, winter driver. None of those are on this policy.
