The M4 has earned a place among the UK’s highest-rated motorways according to a new assessment.
Research conducted by Transport Focus assessed driver contentment levels across major A roads and motorways throughout England.
The A30, connecting west London with Cornwall, and Kent’s M20 achieved top positions in the rankings, while the M27 in Hampshire occupied the bottom spot.
The assessment, which examined the year leading up to March 2026, also documented advances in travel durations, road condition standards, and construction zone administration.
Transport Focus director Louise Collins noted that satisfaction levels have risen overall and there are positive indicators that motorists recognise enhancements in important areas, though she added that construction work continues to significantly affect travel experiences.
She stated that by implementing successful approaches from recent projects, National Highways could ensure that roadworks are strategically organised, effectively communicated to the public, and cause minimal inconvenience wherever feasible.
RAC Foundation director Steve Gooding pointed out that managing construction zones effectively plays a vital role in driver contentment.
He indicated that the findings suggest National Highways will need to elevate performance more uniformly throughout England given the substantial maintenance programme scheduled for the network until 2030.
National Highways is currently undertaking an extensive five-year renewal scheme.
This initiative forms part of the third Road Investment Strategy and is anticipated to represent one of the most significant periods of maintenance activity since the 1960s.
A National Highways representative commented that roads are managed to maintain the highest safety standards while reducing inconvenience for road users.
According to the spokesperson, the survey results demonstrate that efforts to enhance road conditions and response times to incidents have produced beneficial outcomes for drivers.
The representative added that proper road maintenance benefits both businesses and local communities, and the organisation remains dedicated to addressing an aging infrastructure network to keep the nation moving and improve driver experiences.
The assessment identified the following top-performing A roads and motorways in England alongside their satisfaction percentages:
The A30 achieved 79 percent, the M20 also reached 79 percent, the M56 recorded 78 percent, the M5 obtained 78 percent, the A19 reached 77 percent, the A23 secured 77 percent, the M4 achieved 76 percent, the A14 also recorded 76 percent, the A303 reached 74 percent, and the M40 obtained 74 percent.
The assessment incorporated responses from over 9,500 motorists nationwide.
Examining the M4 specifically, this route ranked seventh among A roads and motorways in the Transport Focus assessment with a satisfaction level of 76 percent, matching the score achieved by the A14.
Covering approximately 189 miles and traversing locations including Reading, Swindon, Bristol, Newport, Cardiff, and Swansea, the motorway connects West London with Southwest Wales.
Nevertheless, motorists participating in online discussions appear to dispute these findings, with numerous individuals describing sections of the M4 as among the most challenging in existence.
One Reddit contributor remarked that the section between Magor Services and Coryton represents the single most demanding stretch of motorway anywhere globally, noting an extraordinary density of poor driving behaviour per kilometre.
Another motorist characterised the M4 as a highly problematic stretch of highway.
A further Reddit user observed that the M4 route into Wales via the Newport tunnels constitutes the most unpopular motorway in the United Kingdom.
These observations align with research published by the AA earlier in the year, which identified the M4 among the UK’s lowest-rated motorways.
