Your rear-end crash claim does not disappear just because you were driving between showings.

That's the first thing.

In South Portland, a real estate agent bouncing from Meetinghouse Hill to Ferry Village to a condo near the Maine Mall is usually driving a personal car for work. When somebody slams into the back of that car on Broadway, Cottage Road, or near the Veterans Memorial Bridge, three insurers can immediately start acting cute about whose problem this is.

Usually the lineup looks like this:

• the rear driver's liability insurer
• your own personal auto insurer
• your brokerage's commercial policy, often a hired/non-owned auto policy

Here's the ugly part: each one may cover something different, and each one may try to pretend the other carrier should go first.

A rear-end crash is still a rear-end crash

Maine is not a no-fault state. The basic rule is simple: the driver who hit you from behind is the starting point for liability.

If you were stopped, slowing, or moving normally in traffic and got hit from the rear, that other driver has a real problem. No bike lane, no shoulder, no weird road design issue changes that. On South Portland roads, especially around Broadway, Main Street, and the ramps feeding toward I-295 and the Turnpike spur, rear-end crashes happen because people tailgate, glance at GPS, or flat-out stop paying attention.

The fact that you were "working" does not let the at-fault driver's insurer off the hook.

They may still try it.

Expect language like this: "Since the vehicle was being used for business, we need to confirm whether another policy is primary." That sounds technical. It often means, "We don't want to pay until somebody forces us."

Why your own insurer suddenly cares that you were between showings

A lot of Maine drivers assume their personal policy only matters if they caused the crash.

Not true.

Your insurer may get dragged in for collision coverage on your car, MedPay if you bought it, and uninsured or underinsured motorist coverage if the rear driver has weak limits or the claim goes sideways. But the minute you tell them you were driving from one listing to another, they may start asking whether the car was being used "in the business of" real estate.

That does not automatically kill coverage.

Most personal auto policies are not written to exclude every bit of work-related driving. A real estate agent using a personal SUV to get between showings is not the same thing as using a car as a taxi, delivery rig, or snowplow. But insurers love gray areas. If you had signage on the car, regular client transport, or a policy application that said the vehicle was just for personal commuting, the company may start poking at misrepresentation or business-use issues.

That's where people get blindsided.

Your brokerage's policy may exist, but it may not help the way you think

Brokerages in Maine often carry hired and non-owned auto coverage. That sounds promising. It usually is not a magic fix.

That kind of policy is commonly there to protect the business if the company gets sued because you were out doing company work in your own car. It often covers the brokerage's exposure, not necessarily your vehicle damage, and not necessarily your full injury claim. It may be excess coverage, meaning it only kicks in after the at-fault driver's policy or your own policy is exhausted.

So the brokerage carrier says, "We're excess."

Your own carrier says, "This may be business use."

The rear driver's carrier says, "We need to sort out the employment angle."

And meanwhile your car is sitting in a yard in Cumberland County collecting storage fees.

The job-duty question matters more than the clock on the dashboard

If you were truly between showings, on the phone with a client, heading to an open house, or carrying listing materials, you were likely in the course of work activity. That can also trigger a workers' comp issue if you were injured.

That's the fourth lane of the mess, and yes, it can overlap with the auto claim.

Workers' comp in Maine can cover medical treatment and lost wages for an employee hurt in the course of employment, even in a vehicle crash. Many real estate agents, though, are classified as independent contractors, which changes the fight completely. Brokerages love that setup until somebody gets hurt.

So one of the first factual disputes is not even about the crash. It's about your work status.

Employee or independent contractor.

Personal errand or active showing route.

Driving for your own business or for the brokerage.

That stuff decides which insurer gets to stall.

What actually moves the claim in South Portland

The fastest way to cut through the finger-pointing is evidence that nails down two things: fault and purpose.

Fault means the rear-end facts. Photos of damage. Crash report. Vehicle positions. Witnesses. Camera footage from a nearby business on Broadway or Ocean Street if you can get it before it disappears. Rear damage patterns usually tell a blunt story.

Purpose means proof you were between showings. Calendar entries. MLS appointment confirmations. Texts with clients. Call logs. Showing sheets. GPS history. The exact address you left and the exact address you were driving to. If the crash happened during a sloppy March storm right after a nor'easter pushed traffic into a greasy mess near the Turnpike, weather matters too, but it doesn't excuse following too close.

Most people don't realize this: when three insurers are circling, the paper trail matters more than the arguments. The adjusters aren't impressed by fairness. They're impressed by records.

Maine's fault rule is the other trap

If one of these companies can pin enough blame on you, they will try. Maine follows modified comparative fault. If you are found 50% or more at fault, recovery can be barred.

In a straight rear-end hit, that usually means the other side may claim you stopped short, had bad brake lights, or made an erratic turn. On roads with no bike lane or no shoulder, that kind of blame-shifting shows up fast because insurers think roadway layout gives them room to muddy the story.

It doesn't, unless the facts support it.

If you were rear-ended while driving your own car between South Portland showings, the fight is usually not about whether some policy exists. It's about which company has to write the first serious check, and every day they delay is a day they keep their money and you deal with the wreck.
