Not a Drop, Not a Drag: The Dangers and Legal Penalties of Drinking and Driving

Understanding how drink and drug driving affects your judgement, reaction times, and awareness can help you make safer choices and avoid severe legal consequences.

Drink Driving in Northern Ireland: Legal Limits

The legal alcohol limit for drivers in Northern Ireland is:

• 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

It’s important to remember that alcohol affects drivers long before they reach the legal limit. Even small amounts can impair your judgement, concentration, and reaction time.

How Alcohol Affects Your Driving

At Less Than One-Third of the Legal Limit

Even at relatively low levels of alcohol consumption:

• Your attention becomes impaired.
• You focus more on steering and less on hazards around you.
• You may fail to spot pedestrians, cyclists, or other road users.
• Alertness decreases.
• The likelihood of tiredness and drowsiness increases.

At Less Than Half of the Legal Limit

As alcohol levels rise:

• Vigilance decreases.
• Your perception begins to deteriorate.
• Your ability to assess situations accurately becomes reduced.

At Three-Quarters of the Legal Limit

By this stage, alcohol significantly affects:

• Vision and eyesight
• Tracking ability
• Lane positioning
• Steering control

You may also struggle to:

• Judge distances correctly
• Assess vehicle speeds accurately
• React safely to changing road conditions

At Four-Fifths of the Legal Limit

Closer to the legal limit, drivers may experience:

• Impaired thinking and decision-making
• Slower reaction times
• Reduced ability to make safe choices
• Increased confidence and risk-taking behaviour

Many drivers mistakenly believe they are fully in control, when in reality their judgement is severely affected.

The Overall Impact of Alcohol on Driving

Alcohol can cause:

• Blurred vision
• Reduced concentration
• Poor judgement
• Slower reactions
• Increased risk-taking

The combined effect makes drivers significantly more likely to be involved in a collision.

The Hidden Dangers of Drug Driving

Many people associate drug driving with illegal substances, but certain prescription and over-the-counter medicines can also affect driving ability.

Examples include some:

• Hay fever medications
• Cold and flu remedies
• Cough medicines
• Prescription painkillers
• Sedatives

Always read the patient information leaflet supplied with medication and seek advice from your doctor or pharmacist if you’re unsure whether it is safe to drive.

How Drugs Affect Driving

Drugs can:

• Slow reaction times
• Reduce concentration
• Affect coordination
• Impair judgement
• Cause drowsiness
• Blur vision

Drivers under the influence of drugs may also:

• Misjudge distances and speeds
• Take unnecessary risks
• Become overconfident
• Fail to respond quickly during emergencies

Just like alcohol, drugs can significantly increase the risk of serious or fatal road traffic collisions.

You could receive:

• A fine of up to £2,500
• A driving disqualification period determined by the District Judge

Why Drink and Drug Driving Is Never Worth the Risk

The consequences of drink or drug driving extend far beyond fines and driving bans. A single poor decision can result in:

• Serious injuries
• Loss of life
• Criminal convictions
• Increased insurance costs
• Loss of employment opportunities
• Long-term emotional and financial consequences

The safest option is simple: if you’ve been drinking or taking medication that may impair your driving, don’t drive. Arrange alternative transport or wait until you’re fully fit to drive again.

Stay Safe on the Roads

No matter how experienced you are behind the wheel, alcohol and drugs can affect your judgement, reaction times, and ability to make safe decisions. Understanding the risks and legal consequences can help protect you, your passengers, and everyone else on the road.

Remember: Not a drop. Not a drag. No journey is worth the risk.
