Port Drayage Insurance in Miami: Trailer Interchange, Explained

The one coverage that decides whether PortMiami lets you pull a box — and what it actually costs.

Quick answer: If you pull containers out of PortMiami or Port Everglades, you're hauling equipment you don't own — steamship-line containers and pool chassis. Trailer interchange (or non-owned trailer) coverage pays for damage to that equipment when you're responsible under a written interchange agreement, and terminals generally require it before they'll let you work. Budget roughly $10K–$22K/year for a full Miami drayage owner-operator program.

Miami drayage is its own world. You're not hauling your own trailer down the interstate — you're pulling a steamship line's container on a pool chassis, in and out of terminals that won't even open the gate unless your insurance is exactly right. The coverage that trips up new drayage operators isn't liability or physical damage. It's trailer interchange.

What trailer interchange actually covers

Trailer interchange insurance covers physical damage to trailers, chassis and containers you pull but don't own — collision, fire, theft and vandalism — when you're legally responsible for that equipment under a written interchange agreement. In drayage you sign those agreements constantly: with the steamship line, the chassis pool (POOL, TRAC, DCLI), and other carriers.

Here's the gap it fills: your own physical damage policy covers your truck and your trailer. It does nothing for a $40,000 chassis or a damaged container that belongs to someone else. If you crack a chassis or drop a box, the equipment owner bills you — and without trailer interchange, that bill is yours personally.

Trailer interchange vs. non-owned trailer coverage

The two get used interchangeably, but they're not identical. Trailer interchange responds when there's a written interchange agreement in place (the norm for port drayage). Non-owned trailer coverage is broader and can respond even without a formal interchange agreement — useful if you occasionally pull a trailer for a friend or a broker. Serious drayage operators usually carry trailer interchange with a limit that matches the equipment they pull; many carry both. We match the form to your actual contracts so there's no gap and no wasted premium.

Why PortMiami won't let you skip it

Terminal access agreements and drayage contracts at PortMiami and Port Everglades generally require trailer interchange or non-owned trailer coverage — commonly $30,000–$50,000 or more per unit — plus your standard auto liability (usually a $1,000,000 combined single limit) and often a cargo limit. The certificate of insurance has to show those exact limits and, frequently, the terminal or line as an additional insured. If the COI is wrong, the gate stays closed. NextGuard issues drayage COIs with the correct interchange limits and additional-insured wording the same day.

Watch the chassis split. On a "motor-carrier-provided chassis" move you're responsible for the chassis; on a "merchant haulage" or line-provided move the responsibility can shift. Your interchange coverage and limit should be set for the worst-case equipment you actually pull, not the best case — a mismatch here is how drayage operators end up personally on the hook.

The rest of a Miami drayage program

• Commercial auto liability — primary liability; FMCSA requires $750,000 for general freight (most drayage), and shippers/terminals commonly require $1,000,000.
• Physical damage — collision and comprehensive on your tractor, with Miami's theft and unsecured-parking exposure priced in.
• Trailer interchange / non-owned trailer — the equipment you pull but don't own.
• Motor truck cargo — the freight inside the box; some drayage lanes need contingent cargo even when the cargo isn't your primary responsibility.
• Non-trucking liability (bobtail) — if you're leased to a carrier and drive off dispatch.

What it costs in 2026

A Miami owner-operator running port drayage generally pays about $10,000–$22,000 per year for a full program (auto liability, physical damage and trailer interchange). What moves the number: your driving record and years of experience, whether you park in a secured lot overnight, your radius, and whether your authority is new. New-authority drayage operators sit at the top of the range for the first year or two; a clean record and a couple of loss-free years bring it down meaningfully.

Frequently asked

Is trailer interchange the same as cargo insurance?

No. Trailer interchange covers the equipment (chassis/container) you don't own. Cargo covers the goods inside. Drayage operations often need both.

What limit of trailer interchange should I carry?

Enough to replace the most valuable unit you pull — typically $30K–$50K, sometimes higher for refrigerated containers. We set it to your contracts.
