Understanding Commercial Tow Bars and the LAS in the UK

In the logistics and transportation industry, the humble tow bar plays a crucial role in enabling commercial vehicles to haul heavy loads, trailers, or equipment. In the UK, commercial tow bars are subject to stringent standards to ensure safety, durability, and legal compliance. Among the regulatory frameworks governing these devices, the LAS — or Law Assured Standards — sets essential guidelines that manufacturers and operators must adhere to.

What Are Commercial Tow Bars?

A commercial tow bar is a mechanical device fitted to the chassis of a vehicle, enabling it to tow another object such as a trailer, caravan, or specialised equipment. These tow bars are designed for heavy-duty applications and are typically found on:

  • Trucks and lorries
  • Vans and fleet vehicles
  • Recovery vehicles
  • Agricultural machinery

Depending on their usage, commercial tow bars may be fixed, detachable, or retractable. They must be strong enough to handle significant loads while providing stability and safety during towing operations.

The Importance of Compliance with UK Standards

In the UK, vehicle modifications—including tow bar installations—must comply with national and EU regulations. This is where LAS (Law Assured Standards) becomes significant. The LAS framework ensures that towing equipment meets safety, design, and performance benchmarks before being approved for commercial use.

Key regulatory bodies involved include:

  • VCA (Vehicle Certification Agency): Approves type-approval standards for vehicles and components.
  • DVSA (Driver and Vehicle Standards Agency): Enforces roadworthiness and compliance during annual inspections.

Tow Bar Regulations Under LAS

Tow bars fitted to commercial vehicles in the UK must conform to:

  1. EC 94/20 or UNECE Regulation 55: These outline specifications for tow bar strength, compatibility, and safety features.
  2. Type Approval: Any commercial tow bar must be type-approved for the specific vehicle model it’s fitted to. This guarantees the product has been tested under strict conditions.
  3. Installation Requirements: Tow bars must be installed by certified professionals using manufacturer-supplied fitting kits. Improper installation can result in MOT failures and road safety hazards.
  4. Weight and Load Limits: The gross train weight (GTW) of a vehicle, which includes the vehicle and the trailer, must not exceed manufacturer or legal limits.

LAS and Road Safety

The Law Assured Standards framework plays a key role in promoting road safety and minimising accidents caused by poor-quality or improperly installed tow bars. According to recent DVSA data, a significant number of roadside failures and traffic incidents involving commercial vehicles were linked to towing-related faults, including insecure connections and weight overloads.

LAS ensures that all components—including tow bars—are traceable, tested, and verifiable. It also supports better enforcement through MOT inspections, roadside checks, and fleet audits.

Best Practices for Businesses

For fleet managers and commercial operators, adhering to LAS and related standards isn’t just about compliance—it’s about protecting people, cargo, and reputation. Key steps include:

  • Purchasing only type-approved tow bars
  • Ensuring qualified installation
  • Keeping maintenance and inspection records
  • Training drivers on safe towing practices
  • Monitoring GTW and towing limits rigorously

Conclusion

As logistics and fleet operations evolve, safety and compliance remain at the forefront of vehicle management. Commercial tow bars, though often overlooked, are vital components that must meet exacting standards, particularly under the UK’s Law Assured Standards (LAS) framework. Investing in quality, compliance, and training ensures that vehicles tow safely and efficiently while avoiding costly legal penalties or accidents.

For companies relying on commercial towing, understanding the regulatory landscape is essential. Staying ahead of LAS compliance isn’t just good practice—it’s a legal and ethical responsibility.
