National Highways Publishes Updated Guidance on Roadside Facility Signage

National Highways has released a newly updated guidance document detailing how motorway service areas (MSAs) and other roadside facilities should be signed on England’s major road network.

The document, titled Signing of Roadside Facilities on the Motorway and All-Purpose Trunk Road Network, sets out comprehensive advice on the design, placement, maintenance, and funding of signs along the strategic road network (SRN) — including motorways and trunk roads.

According to National Highways, the updated guidance “should be read alongside the current Traffic Signs Regulations and General Directions (TSRGD) and the Traffic Signs Manual (TSM), which provide detailed guidance on the design and use of traffic signs.”

Greater Clarity and New Categories

The revised version introduces expanded provisions for electric vehicle (EV) charging hubs, reflecting the government’s growing focus on sustainable transport infrastructure. It also updates eligibility and spacing criteria for MSAs and roadside facilities.

A spokesperson for National Highways said:

“This guidance ensures that signing for roadside facilities remains consistent, clear and up to date as the road network evolves. It is essential that motorists can quickly identify safe, reliable places to stop, rest, and refuel — whether that’s with petrol, diesel, or electric charge.”

The agency notes that all facilities accessed directly from a motorway or junction must be signed “for safety reasons” and that minimum service requirements apply for a site to qualify for official signing.

Focus on Safety and Consistency

The guidance reaffirms long-standing principles on MSA spacing and safety. It cites the continued aim of ensuring that service areas are located approximately every 30 minutes of driving time along trunk roads and motorways, giving drivers regular opportunities to take rest breaks.

“Roadside facilities perform an important safety function by providing opportunities for the travelling public to stop and take a break during their journey,” the guidance explains.

In addition to safety considerations, the update provides improved technical diagrams, clearer funding processes, and updated design standards for modern sign structures.

Supporting Modern Infrastructure

National Highways says the update supports its wider commitment to improving infrastructure for a new generation of road users — including those driving electric or hybrid vehicles.

“As the road network adapts to new technologies, signage must evolve too,” the spokesperson added. “By modernising the guidance, we’re ensuring consistency across England’s roads and helping operators deliver the facilities motorists expect.”

The document is also intended to assist developers and operators in ensuring that proposed or existing roadside services meet National Highways’ requirements for signing and access.
