In 1974, the drink driving limit in Ireland was significantly different from today’s strict standards, but the exact figures and the stories surrounding them are often misunderstood or distorted by myths.
The Legal Drink Driving Limit in Ireland in 1974
The first official drink driving limit in Ireland was introduced in 1967, setting a blood alcohol concentration (BAC) limit of 80 milligrams of alcohol per 100 millilitres of blood (0.08%). This was the legal standard during the early 1970s, including 1974. However, some sources mention a slightly higher limit in the early 1970s—around 125 mg/100ml blood—before the 80 mg limit became firmly established. This higher limit was linked to the introduction of breathalyser tests in 1969, which initially used a 125 mg/100ml threshold to determine intoxication.
The Myth of the “12 Pint Limit” and Public Reaction
A persistent and widely circulated myth claims that in 1974 Ireland had a “12 pint driving limit” and that this led to violent protests in Dublin. According to this story, motorists were previously allowed to drink up to 22 pints before being considered unfit to drive, and the government’s decision to reduce this to 12 pints caused outrage and riots.
However, this narrative is entirely false and has been debunked multiple times. The “12 pint limit” and the associated protests are fabrications, often originating from satirical or hoax news sources. There is no historical evidence or credible records of such a law or violent demonstrations related to it. The claim that motorists were once legally allowed to drink 22 pints before driving is also untrue and part of the same myth.
What Was Actually Happening in 1974?
In reality, Ireland’s drink driving laws were tightening during the early 1970s in response to rising road traffic fatalities. The introduction of the breathalyser in 1969 gave Gardaí new powers to enforce drink driving laws, and the legal BAC limits were being standardized and lowered to improve road safety.
The confusion around “pints” as a measure likely stems from misunderstandings of alcohol units and how blood alcohol concentration correlates with the amount of alcohol consumed. For example, the state pathologist in 1969 estimated that a man weighing about 11 stone (roughly 70 kg) would reach the 125 mg BAC limit after consuming approximately two and three-quarter pints of beer or four small whiskies. This shows that even a few pints could push a person over the legal limit.
Summary and Context
- In 1974, the legal BAC limit was approximately 80 mg/100ml blood, aligning with the original 1967 law, although some sources mention a transitional period with a 125 mg limit after the breathalyser introduction in 1969.
- The “12 pint limit” story is a myth and has no basis in fact; no such law or violent protests occurred in 1974 or any other time.
- The legal limits were designed to reduce drink driving deaths, which were a serious problem in the early 1970s.
- Alcohol consumption equivalent to just a few pints could exceed the legal limit, depending on body weight and metabolism.
The drink driving limit in Ireland in 1974 was governed by laws introduced in the late 1960s, with a BAC limit of about 80 mg per 100ml of blood. The sensational story of a 12 pint limit and ensuing riots is a fabrication without historical truth. Understanding the real history of drink driving laws helps dispel myths and highlights the ongoing importance of responsible drinking and road safety in Ireland.
