Vehicle in International Traffic – Legal Position & Compliance Statement

The towed vehicle is intended solely for personal use when the motorhome is stationary (e.g. at a campsite) and will be returned to the United Kingdom upon completion of travel.

This vehicle combination:

  • Is owned by a natural or legal person normally resident in the United Kingdom
  • Is registered in the United Kingdom
  • Is temporarily imported into another State

and therefore qualifies as a vehicle in international traffic under the provisions of the
Vienna Convention on Road Traffic 1968


Trailer Classification (UK Law)

In accordance with guidance from the UK Department for Transport:

When an A-frame is attached to a motor vehicle and towed by another motor vehicle, the A-frame and vehicle together form a single articulated unit.

As such, the unit is classified as a trailer under UK legislation.


Braking System Description

The trailer braking system incorporates power-assisted braking (servo-assisted or full power).

To ensure correct operation:

  • A remote vacuum pump, powered by the towing vehicle, maintains servo assistance
  • A dual-sensing electronic control system activates braking only during deceleration
  • The system allows safe reversing without sustained brake drag
  • Engagement and disengagement are fully automatic

All braking force originates from the towing vehicle and is applied proportionally.


Trailer Identification & Compliance

The trailer (towed vehicle) is compliant with UK trailer requirements and is clearly identified by:

  • Display of the towing vehicle registration number
  • Display of the distinguishing sign of the State of registration (UK)
  • Fitment of red reflective warning triangles
  • Fully synchronised lighting system compliant with trailer regulations

Vehicle Category

The unit falls within:

Category O2 — Trailers with a maximum mass exceeding 0.75 tonnes and not exceeding 3.5 tonnes


Applicable Legislation

The system is designed and operated in accordance with:

  • Road Vehicles (Construction and Use) Regulations 1986 (as amended)
  • Road Vehicles Lighting Regulations 1989 (as amended)
  • UNECE Regulation 13
  • UNECE Regulation 55
  • Directive 71/320/EEC (and amendments)
  • Vienna Convention on Road Traffic 1968

International Legal Recognition

Under the Vienna Convention:

  • Vehicles in international traffic must be recognised as compliant if lawful in their country of registration
  • A host country may not reclassify the vehicle contrary to its domestic classification

Therefore:

The A-frame system, when compliant with UK law, must be recognised as a trailer system in international use.


Enforcement Note

Local enforcement authorities may not always be familiar with international traffic provisions.

For clarity, Tow A Frame Ltd provides:

  • Multilingual documentation
  • Technical system descriptions
  • Legal and legislative references

to support understanding of the system’s classification and compliance.
