The Liberal Democrats have called on the Government for action after a study showed a significant rise in re-offending rates for drink and drug-driving.
According to figures released for 2008, around 24% of people convicted for driving under the influence of drugs or alcohol had committed the same offence before - up from 16% in 2000.
While re-offending rates are highest in the West Midlands at 29%, Bedfordshire, Northumbria, South Wales and West Yorkshire are all experiencing rates over 26%. The Metropolitan Police saw a jump from 14% to 24%.
The political party has accused ministers of putting road users at increased risk.
Road safety spokesman Mark Hunter said: "Labour's record of inaction on drink and drug driving crime is failing Britain and putting our drivers and pedestrians at increased risk.
"We have a drink-drive limit that is 37% higher than European recommendations, and the Government has failed to introduce roadside drugs testing. Labour's warm words on road safety are not enough - action is needed."
