Road safety charity Brake has warned that the government is gambling with people's lives as it moves forward with trials of 80mph speed limits on sections of the motorway.
Former transport secretary Phillip Hammond first proposed the rise in speed limits before he moved to the role of defence secretary in October.
His replacement, Justine Greening, has now moved forward with the plans, beginning with talks with a number of motoring groups over the next few weeks.
A pilot scheme will then see wider motorway sections with overhead display gantries trial the 80mph speed limit, with parts of the M25 already earmarked to the test.
The proposals have been vehemently opposed by Brake since their inception and today (March 19th) deputy chief executive Julie Townsend once again hit out at the plans.
“It is hard to see the logic behind this trial when the potential benefits of 80mph limits are so questionable," she said.
"There is a mountain of evidence that higher speeds result in more needless and violent crashes and casualties."
