Boston dump truck operators anchor to Commonwealth Automobile Reinsurers (CAR) Code 72 (Sand and Gravel) Boston Zone 03 intra-zone bodily-injury 20/40 base rate of $182 per vehicle per year — CAR Massachusetts Commercial Auto Manual page R-11 + Zone Rating Tables, effective October 1, 2024. Massachusetts uniquely maintains 5 named dump-truck sub-classes (71 Excavating / 72 Sand-Gravel / 73 Mining / 74 Quarrying / 79 All Other) in the CAR filing — the most explicit publicly-filed dump-truck taxonomy in any state. The 1.50× collision multiplier for dumping operations + Boston's intra-city aggregate-haul corridors (Boston Harbor remediation, Suffolk Downs redevelopment, ongoing Big Dig-era infrastructure work) define the local underwriting profile. Solo Boston dump-truck operator expect $7,500–$15,000 per year for the full coverage stack.
Boston Zone 03 intra-zone
sub-class taxonomy
dumping operations
idle + axle compliance
Boston's dump-truck market sits on top of three regulatory + commercial characteristics that distinguish it from any other US dump-truck market: CAR Massachusetts's explicit 5-sub-class dump-truck taxonomy (Excavating / Sand-Gravel / Mining / Quarrying / All Other) crossed with zone ratings, the Boston intra-city aggregate-haul corridor density (Big Dig-era infrastructure work + Boston Harbor remediation + Suffolk Downs redevelopment), and the Boston Inspectional Services Department dump-truck-specific idle + overweight axle compliance regime that layers on top of state MA RMV + MassDOT requirements.
What makes Boston dump truck insurance different
- CAR Massachusetts dump-truck sub-class taxonomy — CAR is the only state residual-market filing that explicitly publishes 5 named dump-truck sub-classes (Code 71 Excavating, 72 Sand-Gravel, 73 Mining, 74 Quarrying, 79 All Other), each with its own rating-factor multipliers crossed with zone ratings. The Boston Zone 03 intra-zone Code 72 Sand-Gravel base of $182/vehicle/yr is the most-precise dump-truck-specific filed rate in any US state's residual-market filing.
- Boston intra-city aggregate-haul corridors — Boston Harbor remediation, Suffolk Downs redevelopment, Seaport district build-out, and ongoing Big Dig-era infrastructure work sustain a high density of intra-city aggregate-haul traffic. Dump-truck operators servicing these corridors face distinct Commercial Auto loading vs suburban-only operators.
- 1.50× collision multiplier for dumping operations — CAR Massachusetts applies a 1.50× collision-coverage multiplier to dumping-operation exposures, reflecting the elevated upset / rollover / dumping-cycle accident frequency. Boston dump-truck operators commonly carry comprehensive Physical Damage limits + scheduled dumping-operation analysis.
- Boston Inspectional Services Department compliance — Boston ISD enforces dump-truck-specific idle restrictions, overweight axle ordinances, and intra-city operating permits separate from state-level MA RMV + MassDOT registration. Multi-layer compliance stack distinct from rural Massachusetts dump-truck operations.
The coverage stack a Boston dump truck operator needs
The standard dump-truck stack from the parent Dump Truck Insurance Guide applies — Primary Commercial Auto Liability ($1M CSL minimum for Boston intra-city work), Physical Damage with CAR Massachusetts 1.50× dumping-operation collision multiplier analysis, Motor Truck Cargo (aggregate-haul specific), General Liability, Workers Comp, MCS-90 federal backup for any state-line work, and Jobsite / Off-Road endorsement (standard Commercial Auto excludes off-road operations unless specifically endorsed — a coverage gap the pillar guide flags as critical). Boston additions: Massachusetts DEP excavation + materials-handling permit documentation, MA RMV dump-truck commercial registration, MassDOT oversize/overweight permit, and Boston ISD dump-truck-specific intra-city permit + idle compliance.
How much does Boston dump truck insurance cost?
- Solo single-axle dump truck, intra-Boston aggregate haul — $7,500-$15,000/year for the full stack.
- Solo tri-axle dump truck (higher GVWR + heavier loads) — $12,000-$22,000/year.
- Small dump-truck fleet (3-5 trucks, mixed sub-class) — $35,000-$80,000/year.
- Mid-size aggregate-haul fleet (10-20 trucks) — $140,000-$340,000/year.
- CAR residual placement (Code 72 Sand-Gravel Boston Zone 03) — $182/year per vehicle for the BI 20/40 base layer + 1.50× dumping-operation collision multiplier — operators with adverse MVR / claims history land here when voluntary CAR-participating carriers decline.
Massachusetts commercial auto + dump truck context
Massachusetts is among the eight independent-state-bureau commercial- auto states. Commonwealth Automobile Reinsurers (CAR) operates the residual market with the most detailed publicly-filed dump-truck-specific rate taxonomy in any US state: 5 named sub- classes (Code 71 Excavating, 72 Sand-Gravel, 73 Mining, 74 Quarrying, 79 All Other) crossed with zone ratings (Zone 01-05) and intra-zone vs cross-zone movement. The 2024 CAR Massachusetts Manual page R-11 + Zone Rating Tables set Code 72 Sand-Gravel Boston Zone 03 intra-zone BI 20/40 base at $182 per vehicle per year (with 1.50× collision multiplier for dumping operations).
Filed rates: what state regulators actually approve
Insurers can't charge whatever they want for commercial coverage — they must file their rates publicly with each state's Department of Insurance (DOI). Those filings are primary-source, government-held pricing records available via SERFF Filing Access (filingaccess.serff.com). The filed loss cost is the most authoritative starting point for "how much does this cost" — more authoritative than any blog estimate, including ours when not anchored to a filing.
Here's the actual 2024 Commonwealth Automobile Reinsurers (CAR) Massachusetts Commercial Auto Manual rate for Code 72 (Sand and Gravel, Boston Zone 03 intra-zone) — CAR Commercial Auto Manual page R-11 + Zone Rating Tables, effective October 1, 2024. CAR is the only state residual-market filing that publishes 5 named dump-truck sub-classes (71 Excavating / 72 Sand-Gravel / 73 Mining / 74 Quarrying / 79 All Other), each with its own rating-factor multipliers. The Boston Zone 03 intra-zone Code 72 base of $182/vehicle/yr (BI 20/40, with 1.50× collision multiplier for dumping operations) is the most-precise dump-truck-specific filed rate in any US state's residual-market filing. Boston voluntary-market operators typically pay materially LOWER than this residual ceiling — voluntary CAR-participating carriers underwrite below the assigned-risk floor for clean operators with documented Massachusetts DEP + Boston ISD compliance.
About this filing: This is a residual-market base rate — the filed value is dollars per vehicle annual (Bodily Injury Liability) for risks placed in the assigned-risk pool, not a per-$100-payroll loss cost, so the standard modal-payroll triangulation doesn't apply. Voluntary-market commercial auto quotes from standard carriers typically run materially lower than these residual-market ceiling rates. ISO commercial-auto loss-cost filings and per-carrier LCM captures are in our mining queue — see our Rate Changes Tracker as voluntary-market filings land.
How to read filed rates: the filed value is the advisory loss cost (NCCI for WC) or manual base rate (carrier filings for GL / Auto) — what carriers and rating organizations submit to regulators as the actuarial starting point. The actual quote you receive applies a Loss Cost Multiplier (LCM) the carrier filed separately, plus rating factors for territory, payroll, experience modifier (Mod), and schedule credits or debits. Same loss cost × different LCM = why two carriers quote you very different prices for the same business.
Honest note on what we triangulate and what we don't: the GBC triangulation above uses our real funnel's modal payroll bracket × the filed loss cost × a typical LCM range — that's the expected actual premium derived from primary-source data, not a measured quote median. We don't currently capture carrier-quoted premiums on our leads (the partner integrations track acceptance status, not pricing), so we cannot yet say "the actual median of N quotes was $X." We are building a Quote-Outcome capture layer specifically to add that measured median; until it ships, the figure above is the expected premium implied by the filing, paired with the real GBC payroll distribution. See our methodology page for the full breakdown of what we measure today and what we are adding.

Quick glossary — Boston dump truck operations
- CAR Code 72 Sand-Gravel
- CAR Massachusetts dump-truck sub-class for sand, gravel, and similar aggregate hauling operations. One of 5 named sub-classes in the CAR Commercial Auto Manual; rating-factor reflects dump-cycle exposure profile distinct from excavating (Code 71), mining (Code 73), quarrying (Code 74), or all-other (Code 79) operations.
- Boston Zone 03 Intra-Zone
- CAR's zone-rating geographic designation for intra-Boston metro operations. Distinct rate basis from cross-zone or extra-zone movement. Boston Zone 03 intra-zone is the most common operating zone for Boston-based dump-truck operators servicing intra-city aggregate corridors.
- Dumping-Operation Collision Multiplier
- 1.50× collision-coverage multiplier CAR Massachusetts applies to dump-truck operations, reflecting elevated upset / rollover / dumping-cycle accident frequency. Comprehensive Physical Damage limits + scheduled dumping-operation analysis are typical for Boston dump-truck operators.
- Boston ISD Dump-Truck Compliance
- Boston Inspectional Services Department dump-truck-specific permit + idle restriction + overweight axle ordinance compliance. Separate from state-level MA RMV + MassDOT registration.
- Jobsite / Off-Road Endorsement
- Critical coverage layer: standard Commercial Auto policies EXCLUDE off-road / jobsite operations unless specifically endorsed. Dump-truck operators must explicitly schedule jobsite scope at binding — a coverage gap the parent pillar guide flags as critical.
