Julie Townsend, deputy chief executive for Brake, said: "We are disappointed and concerned by this announcement.
“When vehicles travel faster, it takes them longer to stop, increasing risk. It is very well evidenced that increases in speed equal increases in crashes and casualties.
“At the same time, the road safety justification for this move is dubious: we are not aware of evidence it will help tackle risky overtaking, which should be addressed through other means.
“Pronounced speed differences between traffic can pose a risk, but the way to address this is by preventing car drivers going too fast, not speeding trucks up. The minister says she wants to get the country moving, but we ask at what cost to road users and the environment?"
