Weymouth drivers pay less for car insurance than the Massachusetts minimum-coverage average, which raises an obvious question for anyone who has sat through a Fore River Bridge opening on their way to work.

The drawbridge connecting Weymouth to Quincy has to swing open for large vessels moving up the Fore River, sometimes with barely any warning, and it has been known to get stuck open entirely. It sounds like the kind of unpredictability that should push rates up. Instead, a low local crime rate and a modest commute along Route 3 keep Weymouth's numbers on the cheaper side of the state.

Weymouth Auto Insurance at a Glance

  • Minimum liability required: 25/50/30 (statewide floor, same everywhere in Massachusetts)
  • Average premium: ~$101.80/mo (~$1,220/yr), below the state's ~$111/mo minimum-coverage average
  • Cheapest carrier on average: State Farm, around $62.30/mo
  • Population: roughly 60,300
  • Notable rate factor: the Fore River Bridge, a drawbridge that opens on signal for large vessels
  • Fault system: No-fault, with mandatory $8,000 PIP

What Every Weymouth Policy Still Has to Carry

The legal floor in Weymouth is the same as anywhere else in Massachusetts: 25/50/30 liability — $25,000 bodily injury per person, $50,000 per accident, $30,000 property damage — plus mandatory $8,000 Personal Injury Protection and 25/50 uninsured/underinsured motorist coverage, none of which can be waived off a policy.

Because Massachusetts runs no-fault, that PIP pays a driver's own medical bills and lost wages first after a crash, regardless of who caused it. Our Massachusetts car insurance guide covers how the rest of the no-fault system works statewide.

The Fore River Bridge and Its Unscheduled Openings

The Fore River Bridge spans the Weymouth Fore River between Weymouth and Quincy, and by federal rule it has to open on signal for self-propelled vessels over 10,000 gross tons — a threshold that covers the tankers and barges that regularly move through. Openings can come with just a few minutes' notice, and the bridge has occasionally gotten stuck open, backing up traffic on both sides for hours at a stretch.

It's more of a daily annoyance than something an insurer rates line by line, but a bridge that strands commuters with little warning tends to become the first thing locals mention when a car insurance conversation comes up.

Compare that to Quincy just across the bridge, where flood exposure along the harbor is the bigger factor in local rates. Weymouth's story is less about water damage and more about a low crime rate offsetting an unpredictable commute.

A Crime Rate That Keeps Premiums Down

Weymouth's overall crime rate sits roughly 39% below the national average, and property crime — the category covering auto theft and vandalism — runs about 63% below the national average. That combination gives insurers less claims history to price against, and it's a meaningful part of why Weymouth's average premium undercuts the state's minimum-coverage figure despite the bridge and the Route 3 commute.

SouthField, Growth, and Route 3 Traffic

Weymouth has grown to roughly 60,300 residents, helped along by SouthField, the mixed-use development built on the former South Weymouth Naval Air Station. New housing means more registered vehicles and more drivers merging onto Route 3 and the Greenbush commuter rail corridor toward Boston.

Growth alone hasn't pushed Weymouth's average above the state benchmark yet, but it's the kind of trend that tends to nudge local rates upward over time as claims volume catches up with population.

Next Step for Weymouth Drivers

Confirm a policy carries at least 25/50/30 liability and the mandatory $8,000 PIP — that part doesn't change no matter which side of the Fore River Bridge a driver lives on. Beyond the floor, comparing a few quotes matters more in Weymouth than chasing a single average, since carriers like State Farm, USAA, and Preferred Mutual can land tens of dollars apart for the same driver.
