If you're shopping for auto transport, you've probably been asked which one you want: open or enclosed. The default in the industry is open transport; the multi-vehicle car carriers you see on highways with vehicles stacked in the open air. Enclosed transport puts the vehicles inside a sealed trailer, protected from weather and road debris.
Open is cheaper, more available, and what about 95% of all consumer auto shipments use. Enclosed is more expensive, harder to book, and a meaningful upgrade for the right vehicle. Here's how to know which one you actually need.
What open transport is.
Open transport uses the standard car carrier you've seen on the highway: typically a two-level trailer that can hold 7 to 10 vehicles, all exposed to the elements. The cars are secured with straps and chains. The trailer is open on top, on the sides, and (usually) on the bottom.
The risks of open transport are real but limited. Vehicles can pick up road grime, dust, and the occasional small pebble strike from the road or from the wheels of the truck itself. In bad weather, vehicles can get rained or snowed on. The damage that does happen tends to be cosmetic and minor: a paint chip here, a windshield ding there.
For the vast majority of vehicles, this risk is acceptable. A daily driver in good condition that you don't mind washing on arrival is fine on open transport.
What enclosed transport is.
Enclosed transport uses a sealed trailer, typically holding 2 to 6 vehicles. The trailer is fully enclosed; no exposure to weather, no road debris, no UV. The loading process is more careful, often using soft straps instead of chains and lift gates instead of ramps.
The trailers are smaller, the loads are smaller, and the carriers running enclosed equipment tend to specialize in higher-end vehicles. Enclosed shipments cost roughly 50% more than open on average, sometimes more for specialty vehicles or rare equipment.
When enclosed is worth it.
Enclosed makes sense in a few specific situations:
The vehicle is high-value. Once you cross into the territory of $80,000+ vehicles, the cost premium of enclosed is small relative to the value being protected. A $200 difference in shipping cost is irrelevant on a $150,000 car.
The vehicle has show-quality paint or finish. Concours-grade paintwork, custom finishes, vinyl wraps, and matte clear coats are all more vulnerable to road grime and small impacts than standard factory paint. The upgrade pays for itself in not having to redo the work.
The vehicle is being shipped in winter or through bad weather regions. Salt, slush, and freezing temperatures are harder on a vehicle in transit than most shippers realize. For a sensitive vehicle in winter, enclosed is the safer call.
The vehicle is a classic, exotic, or one of a kind. If you can't replace it, the math on protection becomes different. Enclosed is the standard for any vehicle where the original-condition value matters.
The vehicle has very low ground clearance. Loading vehicles with low clearance onto open carriers is harder and riskier; the lift gates on enclosed trailers handle low-clearance vehicles much more safely.
When open is fine.
For most cars, open is the right call:
Standard production vehicles in driver-condition. Daily commuters, family cars, used vehicles being relocated. The cosmetic risk is real but minor and the cost savings are significant.
Short-distance shipments. Less time on the truck means less exposure to whatever can go wrong.
Vehicles you were going to detail on arrival anyway. A wash and a quick clay bar handles almost anything an open transport will throw at a car in average conditions.
Vehicles being shipped to dealers or to be sold. The cosmetic premium of enclosed isn't worth it if the buyer is going to detail the car before resale.
The in-between.
There's a category of vehicles where the call gets harder: enthusiast cars in the $40,000-$80,000 range. Newer Mustangs, Corvettes, Porsches, BMWs that are nice but not irreplaceable. Owners of these cars often agonize over the decision.
The practical answer for most of them: open is fine, but pay attention to which carrier and which trailer position. Top-deck positions on open carriers are safer than bottom-deck (less road debris from the truck's own tires). Some brokers will let you specify top-deck for a small premium; for an enthusiast car this is often a better value than full enclosed.
What to ask your broker.
If you're on the fence, ask the broker two questions:
What's the price difference for enclosed on this route, this week? It varies more than you'd think. On some routes the premium is closer to 30%, on others closer to 80%.
What's the wait time difference? Enclosed capacity is much more limited. If you need the vehicle moved quickly, the wait for an enclosed slot may push you back to open by default.
The answer often makes the decision for you.
