Affected roads include vital routes for holidaymakers, including A2 towards Folkestone and parts of the A303 and A30

A quarter of England’s most important A-roads have electric car charging “cold spots”, according to government figures that suggest significant gaps remain in the infrastructure needed to switch away from fossil fuels.

Twenty-nine out of 107 A-roads that are part of the strategic road network have at least one cold spot, according to data obtained by charging company Zest from the Department for Transport. The cold spots are defined as points where a vehicle with only 10% of its battery remaining would not be able to reach a site with at least six rapid or ultra-rapid devices.
