A long-haul interstate move almost always rides a shared van line: your shipment shares the truck, pickup and delivery run on windows rather than days, and pricing runs on certified weight plus services. This is where the federal paper protections earn their keep — written estimate, order for service, inventory, and the 110% rule on non-binding estimates. Movers running this corridor regularly can quote realistic windows; ask directly how often they run it.

Answer first
Both ends of the move
Maryland movers should hold a Household Goods Mover Registration (annual registration certificate with a unique registration number, issued under Business Regulation Article Title 8.5 and COMAR 09.30.01) from the Maryland Department of Labor, Division of Occupational and Professional Licensing (Household Goods Movers Registration Unit); the Maryland Attorney General's Consumer Protection Division enforces the conduct rules. That's the in-state rule; your interstate leg answers to FMCSA.
Texas movers should hold a Motor carrier certificate of registration with household goods authority (an 'Active' TxDMV certificate number), plus an active USDOT number from the Texas Department of Motor Vehicles (TxDMV), Motor Carrier Division. Useful if you book any local shuttle or delivery help on the destination end.
Federal rules govern the haul itself: active USDOT registration (verify free at ProtectYourMove.gov), written binding or non-binding estimates, an order for service, an inventory at loading, and arbitration access for disputes.
Census median household income runs about $59,623 in Baltimore versus $62,894 in Houston — a higher-cost destination profile that's worth factoring into your first months' budget, not just the move itself.
Weather math changes en route. Origin side: Maryland summers are hot and very humid, which strains crews and can damage humidity-sensitive items like wood furniture and electronics, so early-morning summer moves help. Late August through September can bring heavy rain and flooding from hurricane and tropical storm remnants around the Chesapeake Bay, and winter moves can face snow and ice, especially in western Maryland. Destination side: Texas moving demand peaks in summer, when highs above 100 degrees F are routine across much of the state - schedule loading for early morning, keep people hydrated, and do not leave electronics, candles, medications, or houseplants in a closed van during the heat of the day. Gulf Coast movers should also watch hurricane season (June through November), which can force short-notice rescheduling.
On arrival: 58.0% of Houston households rent (Census ACS), so month-end move-in slots at apartment buildings are the local bottleneck — reserve elevators and docks as soon as you sign.
Census migration data counted 16,116 people moving from Maryland to Texas in the most recent year measured — roughly 310 households a week. Busy lanes mean more trucks, more schedule options, and more competition for your business. Quiet ones reward early booking.
Q & A
They can give you a process: inventory survey (in person or video), then a written estimate. Anyone offering a firm total in sixty seconds without seeing your inventory is either padding it or planning to renegotiate on your driveway. The call gets you started; the survey gets you the number.
Storage-in-transit is a standard, regulated service: your shipment waits in the mover's warehouse under your contract's liability terms, billed daily or monthly. It's usually smoother than renting a self-storage unit and moving twice. Mention the gap dates on your call.
On interstate moves with a non-binding estimate, federal FMCSA rules cap what the mover can require at delivery at 110% of the estimate — remaining charges bill later. It exists to prevent hostage-load pressure, and it only works if your estimate is in writing.
Interstate: an active USDOT number in FMCSA's free lookup, plus complaint history. In-state: Maryland movers should hold a Household Goods Mover Registration (annual registration certificate with a unique registration number, issued under Business Regulation Article Title 8.5 and COMAR 09.30.01) from the Maryland Department of Labor, Division of Occupational and Professional Licensing (Household Goods Movers Registration Unit); the Maryland Attorney General's Consumer Protection Division enforces the conduct rules. Then: written estimate, real address, and a contract you've actually read. Ten minutes, total.
Dates, delivery windows, what your estimate should include — two minutes on the phone answers what no form can.
