Britain's legal drink-drive limit will not be lowered, the Government has announced, despite a Whitehall report suggesting it should be reduced.
Transport secretary Philip Hammond said lowering the limit from 80mg of alcohol per 100ml of blood to 50mg is unlikely to make a big difference and the key is to enforce existing regulations more effectively.
Mr Hammond gave his nod to a set of new measures to tackle drug-driving and drink-driving, which includes buying new testing kits to identify offenders.
Motorists driving under the influence of alcohol and drugs are a threat the safety of other road users and risk accidents that lead to avoidable and unnecessary car insurance claims.
The Government will also look into the case for a new drug-driving law, which would remove the need for the police to prove impairment on a case-by-case basis where a specified drug has been detected.
Mr Hammond said: "Drink-driving and drug-driving are serious offences and we are determined to ensure they are detected and punished effectively."
"It is just as dangerous to drive impaired by drugs as alcohol so we need to send a clear message that drug-drivers are as likely to be caught as drink-drivers and that drug-driving is as socially unacceptable as drink-driving has become. That is why we will approve drug-testing devices and change the law to speed up the testing process, ensuring the police can bring drug drivers to justice."
