The UK’s Department for Transport (DfT) and Highways England (HE) have collaborated to conduct the first trial of new electronic signage displaying real-time fuel prices for drivers.

The new signs are installed on a section of the M5 between Bristol and Exeter, and will enable drivers to make an informed choice about where to refuel their vehicles.

They will show information from the Bridgwater, Gordano, Taunton Deane, Sedgemoor and Exeter motorway service areas.

Roads minister Andrew Jones said: "The government is on the side of the motorist.

"We want road users to be more informed and in better control of their journeys."

"We know the public has been concerned about the price of petrol at service stations which is why we have acted to create a fairer deal.

"This trial will allow drivers to be much better informed about the cost of fuel and make it easier to plan their breaks around the cheapest deals."

The pilot project was announced by Chancellor George Osborne during this year’s Budget.

HE South West regional director Andrew Page-Dove said: "This trial is an important part of a bigger picture – we want road users to be more informed and in better control of their journeys.

"This means they’ll be better prepared, more inclined to plan breaks, have sufficient fuel and have a more positive driving experience."

Running until the end of next year, the trial will be monitored by HE in order to determine the impact of the new service on the behaviour of drivers.
