Quick comparison
| RoRo | Container | |
|---|---|---|
| Fuel limit | ¼ tank or less (typical) | Empty tank + purged lines |
| Personal items | Not allowed (spare tyre/jack only) | Often allowed (declared) |
| Vehicle condition | Must drive on/off | Non-runners OK (winched) |
| Cost | Usually cheaper | Higher but flexible |
| Speed | Faster load/discharge | Extra packing time |
| US ports | Baltimore, JAX, Brunswick, Hueneme | LA/LB, Newark, Oakland |
When RoRo fits
Running cars, standard timelines, lowest cost. You drive to compound (or truck delivers), vehicle rolls onto vessel. Fuel must meet quarter-tank rule.
When container fits
Non-runners, classic cars, shipping household goods with the vehicle, or destinations without regular RoRo service. Tank must be empty.
Fuel prep differs — plan accordingly
Do not assume RoRo rules apply to container. Book the correct drain level with your forwarder before port delivery.
