UK drink driving laws are governed by the Road Traffic Act 1988

The legal alcohol limits in England and Wales are: 

  • 35 micrograms of alcohol per 100 millilitres of breath 
  • 80 milligrams of alcohol per 100 millilitres of blood 
  • 107 milligrams of alcohol per 100 millilitres of urine 

These limits represent the maximum legal threshold. However, the effects of alcohol vary significantly between individuals, meaning that even small amounts can impair driving ability.

What Happens If the Police Suspect You of Drink Driving?

Police officers have several powers when they suspect a driver has consumed alcohol. 

Roadside Breath Test

A police officer may request a roadside breath test if: 

  • They suspect alcohol consumption 
  • You have been involved in a road traffic collision 
  • You have committed a moving traffic offence 

A handheld breathalyser device measures the alcohol level in your breath. If the reading exceeds the legal limit, or if the officer suspects impairment, you may be arrested. 

Arrest and Police Station Procedure

If the roadside breath test indicates alcohol above the legal limit, the police may arrest you and take you to a police station. 

At the station: 

  • A more accurate evidential breath test will usually be conducted. 
  • If the reading exceeds the legal limit, you may be formally charged with a drink driving offence. 
  • In some cases a blood or urine sample may be required.

The evidential test results are typically used as the key piece of evidence in court proceedings. 

What Happens After a Drink Driving Arrest?

Following an arrest for drink driving, the police will decide whether to charge you with an offence. 

Charge and Court Summons

In many cases, drivers are released from the police station and required to attend a Magistrates’ Court at a later date. 

Drink driving offences are generally dealt with in the Magistrates’ Court rather than the Crown Court. 

Court Appearance

At the court hearing, the magistrates will consider: 

  • The breath or blood alcohol reading 
  • Circumstances of the offence 
  • Any aggravating factors 
  • The defendant’s previous driving record 

The court will then determine the appropriate sentence in accordance with the Sentencing Council guidelines.

Drink Driving Penalties in the UK

Penalties for drink driving vary depending on the level of alcohol detected and the surrounding circumstances. 

Driving Disqualification

A drink driving conviction usually results in a minimum driving ban of 12 months

Longer disqualifications may be imposed where: 

  • Alcohol levels are significantly above the limit 
  • The driver has previous drink driving convictions 
  • The offence involved dangerous driving 

Fines

Courts frequently impose financial penalties. The amount will depend on: 

  • The seriousness of the offence 
  • The driver’s income 
  • Aggravating factors involved 

Possible Imprisonment

In more serious cases, particularly where alcohol levels are extremely high or the offence involved dangerous behaviour, the court may impose a custodial sentence. 

Maximum penalties for drink driving can include up to six months’ imprisonment

The precise sentence will depend on the facts of each case. 

Factors That Affect Drink Driving Sentences

When determining penalties, courts consider several aggravating and mitigating factors. 

Examples of aggravating factors include: 

  • Very high alcohol readings 
  • Carrying passengers 
  • Poor driving behaviour 
  • Involvement in a road traffic accident 
  • Previous motoring offences 

Mitigating factors may include: 

  • Early guilty plea 
  • Previously clean driving record 
  • Genuine remorse 
  • Personal circumstances presented to the court 

Each case is assessed individually by the magistrates. 

Can You Defend a Drink Driving Charge?

Although breath test results can provide strong evidence, drink driving allegations are not always straightforward. 

Potential issues may arise in relation to: 

  • Incorrect breathalyser procedures 
  • Unreliable testing equipment 
  • Procedural errors during arrest 
  • Issues with blood or urine sample handling 

A careful review of the evidence can sometimes identify weaknesses in the prosecution case
