7 Things to Check Before Buying a Used Semi-Trailer from Europe

A semi-trailer is a long-term investment. A bad purchase can cost you more in repairs than you saved on the initial price. Here are the seven checkpoints we use at Road Link before certifying any trailer for export.

1. Chassis & Frame

Inspect the mainframe rails for cracks, bent sections, and poor welds. Look underneath — rust on the surface is normal, but deep corrosion on load-bearing sections is a red flag.

2. Axles & Suspension

Check for oil leaks around the hubs. Spin each wheel — excessive play or rough bearing feel means replacement is needed. Air suspension trailers: check the airbags for cracks and the height valves for response.

3. Brakes

All export trailers must have functional brakes. Check brake chamber condition, slack adjusters, and ensure the ABS warning light clears when connected to a tractor unit. Old or seized brakes are a safety and customs risk.

4. Landing Legs

These take a beating every day. Check that both legs retract and extend smoothly, that the gearbox shifts between fast and slow mode, and that the feet plates are not bent or cracked.

5. Floor Condition

For curtainsiders and box trailers, check the wooden floor for rot, soft spots, and broken boards. A full floor replacement is expensive. Aluminum floors are preferable for longevity.

6. Lights & Electrics

All marker lights, brake lights, and indicators must work. Check the 7-pin and 15-pin connector sockets for corrosion. Wiring harness condition on older trailers is critical.

7. Roof & Curtains (for Curtainsiders)

Look for tears, patched sections, and broken ratchet straps. Customs inspectors in many countries will reject a load with a damaged curtain. A full re-curtain costs €800–1,500.

At Road Link, every trailer we export passes this checklist before photos are taken. If you want, we can share the inspection report for any unit in our current stock.
