New research by temporary insurance provider Tempcover has found that 55 per cent of UK motorists have no idea how strong a modern IPA can be, or what that means for their ability to drive legally afterwards. It is a knowledge gap with consequences that go well beyond a breathalyser conversation on the roadside.
IPA has become the most popular beer style in the UK, the first choice for 52 per cent of drinkers according to Tempcover's data. But the range of what falls under that label is enormous. A traditional English IPA can sit anywhere between 3.7 and 7.0 per cent ABV. An American Double IPA pushes that to between 7.5 and 9.5 per cent. That is not a minor variation. A pint of 4.0 per cent lager contains around 2.3 units of alcohol. A pint of 7.0 per cent IPA comes in at close to four units. The legal limit in England, Wales and Northern Ireland is 80 milligrams of alcohol per 100 millilitres of blood. One strong IPA, depending on body weight, metabolism and what you have eaten, can put a driver over it.
Tempcover's head of marketing put the problem in direct terms:
"Even under current laws of 80mg of alcohol per 100ml of blood, the penalties for being caught out are severe. A conviction can instantly invalidate your insurance and leave you with a lasting financial burden. If you're not monitoring the ABV, you're not monitoring your ability to drive legally."
The timing matters. England and Wales are currently operating under the highest drink drive threshold in Europe, a limit that has not been revised since it was set in the 1960s. That is about to change. The UK government's Road Safety Strategy, published in January 2026, has launched a formal consultation on lowering the limit to 50 milligrams per 100 millilitres of blood, matching Scotland and bringing England and Wales in line with most of Europe. At that threshold, even a single pint of standard strength beer could push a lighter person over. A strong IPA would not be a borderline case. It would be over before the glass was empty.

The RAC's own data, based on a Freedom of Information request to the DVLA, shows 220,638 motorists currently hold drink driving endorsements on their licences. A conviction stays on the record for 11 years, can double or triple insurance premiums, and some standard insurers will refuse cover altogether. The government's Road Safety Strategy consultation also includes a proposal for an effectively zero limit of 20 milligrams for new and young drivers, effectively making any alcohol before driving off the table entirely.
The beer market has changed enormously in a decade. The ABV range available on tap at any given pub is wider than most drivers appreciate. The session IPA at 4.2 per cent and the hazy double at 8.5 per cent can look identical in the glass. Asking the bar staff what is in it before you drive home is no longer overcautious. Under the proposed new limits, it is essential.
The only number that actually matters is zero.
