Drive east on Metropolitan Parkway and Harrison Township announces itself two ways: the runways and hangars of Selfridge Air National Guard Base on one side, and the beach, marina, and golf course of Lake St. Clair Metropark on the other. Car insurance in Harrison Township, Michigan has to account for both, because this Macomb County community of roughly 24,000 people runs on a mix of military traffic and lakefront recreation that most suburbs never see together.
Jefferson Avenue (M-29) traces the shoreline through the township, ZIP code 48045 covers the whole community, and the Clinton River empties into Lake St. Clair right along its edge. It's a small footprint with an unusually specific set of local pressures on a policy.

A Township Built Around a Base and a Beach
Selfridge is a joint-use installation — Air National Guard, Army, Navy, and Coast Guard units all operate out of it — and it's enough of a fixture that ZIP 48045 carries "Selfridge" as an alternate city name. That means a meaningful share of Harrison Township drivers are active-duty, Guard, or veteran households who move in and out on orders rather than by choice.
A few miles south along Jefferson Avenue, Lake St. Clair Metropark pulls in a very different crowd: beachgoers, boaters, and golfers heading to one of Macomb County's busiest seasonal parks. Between base traffic and park traffic, Harrison Township's roads carry more visitors relative to its population than a typical suburb its size.
What Michigan Actually Requires Here
Harrison Township doesn't get its own minimum — every driver carries the same default $250,000 per person / $500,000 per accident bodily injury floor as the rest of Michigan, unless they've signed a waiver to opt down to $50,000/$100,000, plus a PIP medical tier chosen at renewal and $1 million in mandatory Property Protection Insurance for damage caused to property other than another vehicle.
Statewide, minimum coverage averages about $879 a year and full coverage closer to $3,161. There's no Harrison Township-specific rate survey, so those statewide figures — adjusted by a quote tied to ZIP 48045 — are the realistic starting point for a household here.
The Lakefront Risk a Liability-Only Policy Misses
Picture a Harrison Township resident who parks along a street near the Metropark during a summer storm off Lake St. Clair. If wind or rising water damages the car, a liability-only policy pays nothing toward that vehicle — liability only covers damage to other people and their property. Comprehensive coverage is what actually responds to storm, flood, and falling-debris damage, and it's worth keeping for anyone living or parking near the shoreline rather than trimming it to save a few dollars a month.
Building the Right Policy for This Township
- Ask about military and Guard discounts by name if you're connected to Selfridge — carriers rarely apply them automatically.
- Re-shop your policy around a PCS move rather than assuming your current carrier still fits.
- Keep comprehensive coverage if you park near the lake or the Metropark regularly.
- Match your PIP tier to your real health coverage instead of defaulting to unlimited.
The Michigan Department of Insurance and Financial Services (DIFS) licenses every carrier writing policies in Harrison Township and handles consumer complaints statewide — worth a check before signing with an insurer you haven't used before.
A military base on one side, a lakefront park on the other, and the same statewide PIP checklist as everywhere else in Michigan — Harrison Township's car insurance picture comes down to matching coverage to who actually drives these roads.
