What Is a Road Safety Audit — and Why It Matters for your project in Hampshire

A Road Safety Audit (RSA) is an independent review of highway design / works to ensure that new or modified roads are safe for all users. It’s a key requirement for planning permission and conducted following GG119 of the Design Manual for Roads and Bridges (DMRB) and TfL’s S2251 A1 (formerly SQA-0170).

Audits must be carried out by qualified, independent audit teams who were not involved in the design of the scheme.

They help identify potential highway safety issues before construction.  This can prevent casualties and injuries to end users, which minimises costly problems, protecting designers, developers, and highway authorities alike.

Typical triggers include:

In short, if your scheme changes how people move on or around the public highway, you’ll need a Road Safety Audit.

Independent, Efficient, and Always Compliant

We know that project deadlines can be tight, and requirements can feel confusing. Our job is to make the process as simple, clear, and quick as possible.

At GTC, every audit is carried out by accredited professionals.  Our teams hold the National Highways Certificate of Competence and are registered with the Society of Road Safety Auditors (SoRSA).

We work independently from design teams to deliver objective, practical feedback that satisfies local highway authorities and planning conditions in Hampshire and around the UK.

Our reports are clear, balanced, and designed to  support design teams, not slow them down.
