A spokesperson from International Driving Association said: “Drink driving should never be encouraged, and our research shows the areas in England and Wales which are the worst offenders when it comes to breathalyser tests.

“The legal alcohol limit in England and Wales for driving is 80 milligrams of alcohol per 100 millilitres of blood or 35 micrograms of alcohol per 100 millilitres of breath. However, there is no way to know how much you can drink and stay under the limit since it can depend on your weight, age, metabolism, the amount of food you’ve eaten and other factors. 

“If you’re driving, it should be recommended that you don’t drink any alcohol at all, as alcohol can seriously alter your ability to judge speed or distance, and slow your reaction, meaning you are more likely to be involved in a collision.”
