TL;DR: Maryland truckers need liability at the registration floor as a legal minimum, but interstate work triggers federal tiers and shippers expect $1,000,000. Add motor truck cargo, physical damage, and workers compensation from the first employee, with petroleum tankers carrying a $1,000,000 PSC permit requirement.
What coverage does Maryland law actually require?
The legal baseline is thinner than most carriers expect. Maryland requires every registered vehicle to carry the state auto minimums of $30,000 per person and $60,000 per accident for bodily injury plus $15,000 for property damage, and for general intrastate freight that registration requirement is the whole statutory story. There is no state operating authority, no Form E filing, and no trucking-specific liability statute for ordinary property carriers. The two exceptions are passenger carriers, which the Public Service Commission permits and monitors, and bulk flammable liquid tankers, which need a PSC permit backed by a $1,000,000 combined single limit policy with the Commission named as certificate holder.
What does interstate work add?
The moment a load crosses a state line, or moves under a through bill of lading that started elsewhere, the federal financial responsibility rules apply. Vehicles over 10,001 pounds hauling ordinary freight need at least $750,000 in liability, oil products push the requirement to $1,000,000, and the most hazardous cargo requires $5,000,000. The insurer files the MCS-90 endorsement or BMC-91X with the FMCSA, and brokers verify those filings before tendering loads. Most Maryland carriers, including intrastate-only fleets, buy $1,000,000 because that is what shipper contracts demand regardless of the legal floor.
What non-liability coverages complete the program?
Motor truck cargo covers the load, and Maryland's freight mix makes limits worth thinking through: port drayage brings container and chassis exposure with interchange agreements that dictate terms, while high-value retail freight moving the I-95 corridor attracts theft. Physical damage protects tractors and trailers against collision, fire, and theft. General liability responds to premises and completed operations claims, and umbrella layers sit over the primary casualty lines for fleets with contract requirements above $1,000,000.
| Coverage | Who requires it | Typical structure |
|---|---|---|
| Auto liability | Registration law, FMCSA, shippers | $750,000 to $1,000,000 |
| Motor truck cargo | Brokers and shippers | $100,000 common |
| Physical damage | Lenders and lessors | Stated value per unit |
| Workers compensation | Maryland WCC, from first employee | Statutory limits |
| Petroleum tanker liability | PSC permit | $1,000,000 CSL |
How does workers compensation work in Maryland?
Coverage is mandatory from the first employee, enforced by the Workers' Compensation Commission. Chesapeake Employers' Insurance Company, the former Injured Workers' Insurance Fund, operates as a competitive state fund, which means trucking accounts have a guaranteed market while still being free to shop private carriers. Misclassifying drivers as independent contractors to avoid coverage is a recurring enforcement target, so owner-operator agreements need to be genuine, documented, and consistent with how the work is actually dispatched.
What about PIP and the state's tort rules?
Maryland is an at-fault state, not no-fault. Insurers must offer $2,500 in personal injury protection on auto policies, but the offer can be waived in writing and commercial fleets routinely do so. The doctrine that matters more is contributory negligence: any fault assigned to a plaintiff bars recovery completely, which shapes how crash claims against truckers are litigated and settled.
How should a carrier build the program?
Start from the freight, not the statute. Identify what your contracts require, confirm whether any operation triggers the federal tiers, set cargo limits to the real value on the trailer, and bind workers compensation before the first hire, because the gap between Maryland's thin legal floor and the market's working standard is exactly where uninsured losses live. Review the whole stack at each renewal, since a new customer, a heavier trailer, or a first interstate load can change the requirements mid-term, and update certificates promptly so shippers never see a lapse.
Real questions Maryland owner-operators and fleet managers ask
What is the legal minimum liability for an intrastate Maryland truck?
The registration minimums of 30/60/15 are the only statutory floor for general intrastate freight. There is no trucking-specific state liability statute, but market and contract standards of $750,000 to $1,000,000 govern in practice.
Do Maryland petroleum haulers need special coverage?
Yes. Bulk flammable and combustible liquid tankers need a PSC permit supported by a $1,000,000 combined single limit policy, with cargo coverage of $5,000 per vehicle and $10,000 aggregate, and the Commission named as certificate holder.
When do federal insurance tiers apply to a Maryland carrier?
Whenever freight crosses state lines or moves under interstate commerce, vehicles over 10,001 pounds need at least $750,000, with $1,000,000 for oil products and $5,000,000 for the most hazardous cargo.
Can Maryland trucking companies buy workers comp from the state?
Yes. Chesapeake Employers' Insurance Company, the former IWIF, is a competitive state fund that any employer can use, and private carriers also write trucking workers compensation, so accounts can compare both.
Is PIP required on Maryland commercial truck policies?
Insurers must offer $2,500 of personal injury protection, but the offer is waivable in writing and most commercial fleets decline it, relying instead on workers compensation and health coverage for occupants.
