June the big month for roadside breath tests​

Did you know that the number of roadside breath tests carried out in June is 50% higher than any other month apart from December?

‘The police always focus on June as, statistically, it’s a drink drive hotspot,” Hunter Abbott, the Managing Director of breathalyser firm AlcoSense Laboratories, explained. “With warmer weather, sporting events and barbeques, June is a month when motorists are more likely to unintentionally drink drive the morning after socialising – posing a risk to themselves and other road users.”

In June 2017 – the latest period for which figures are available – the police breathalysed 36,041 drivers in England and Wales.The monthly average for the rest of the year (excluding the Christmas period) was just 23,840.

Around 10% of motorists tested positive and were arrested in June 2017.Drivers in Merseyside were the most likely to be stopped, with 3,010 breathalysed – followed by Hampshire (2,532) and Thames Valley (2,265).A significant number of convictions (17.8%) were ‘morning after’.

Currently, the alcohol ceiling for motorists is as follows:

Level of alcohol

England, Wales and Northern Ireland


Micrograms per 100 millilitres of breath



Milligrammes per 100 millilitres of blood



Milligrammes per 100 millilitres of urine



How many drinks this actually equates to for any given motorist depends on several factors, including weight, age, sex, metabolism, stress levels and the type of alcohol consumed.
