There is no "grey area" in drink driving sentencing. There is only a cliff edge. Unlike speeding, where you can argue "exceptional hardship" to avoid a ban, drink driving carries a mandatory minimum disqualification of 12 months. It does not matter if you will lose your job. It does not matter if you are the sole carer for a disabled relative. If you are convicted, the Magistrates must ban you.

This absolute nature of the law leads many drivers to plead guilty immediately, believing there is no hope. This is often a mistake. While the penalties are mandatory upon conviction, the conviction itself is not inevitable. The procedures for testing breath, blood, and urine are governed by strict statutory protocols. If the police deviate from these protocols—even slightly—the evidence becomes inadmissible, and the case collapses.

At Motoring Defence, we are specialist drink driving solicitors. We do not rely on sympathy; we rely on science and statute. In this guide, we explain the technical defences that can acquit you, even when the breathalyser says you are guilty.

The "MGDDA" Procedure: The Police’s Script

When you are arrested, the police must follow a complex procedure outlined in the Manual of Guidance for Drink and Drug Driving (MGDDA). This is a 20+ page document. The officer must follow it sequentially.

• The Statutory Warning:Before you blow into the evidential machine at the station, the officer must give you a specific warning (Section 7(6) warning) that failing to provide a specimen is an offence. If they forget this warning, or give it at the wrong time, the entire breath reading is inadmissible.
• The CCTV Check:We routinely obtain the CCTV footage from the police station "intoximeter room." We watch the procedure frame-by-frame. Did the officer check your mouth for "mouth alcohol" (residue from a recent drink or vomit)? Did they interrupt the machine’s self-calibration cycle? These errors happen surprisingly often in busy custody suites.

"Failing to Provide": The Panic Trap

Sometimes, a driver is charged not with drink driving, but with "Failing to Provide a Specimen." This happens when you try to blow into the machine but fail to register a reading, often due to panic, asthma, or a small lung capacity.

• The Risk:This is a separate offence that carries the same (or often harsher) penalties than drink driving itself, including a potential prison sentence for "deliberate refusal."
• The Medical Defence:We instruct specialist respiratory consultants to prove that you were physically unable to provide the sample. If we can prove you had a "Reasonable Excuse" (such as a panic attack constricting your chest), you are not guilty.

The "Hip Flask" Defence: Drinking After Driving

What if you were sober when you drove, but drank alcohol after you stopped? Perhaps you had an accident, went home shaken, and poured a stiff drink to calm your nerves before the police arrived. This is known as the "Hip Flask" Defence.

• The Science:The police test shows you are over the limit now. It does not prove you were over the limit then.
• Back Calculation:We instruct forensic toxicologists to perform a "back calculation." They take your height, weight, and the amount of alcohol consumed post-driving to mathematically prove that, at the time of driving, you were under the legal limit. This is a complex scientific defence that generalist lawyers rarely understand how to commission.

Sentencing: Keeping You Out of Prison

If the evidence is irrefutable, the focus shifts to damage limitation. Sentencing is based on your alcohol reading (in micrograms, µg).

• 35µg - 50µg:Usually a 12-16 month ban and a fine.
• 90µg - 119µg:A "High Level" Community Order (unpaid work).
• 120µg+:The starting point is 12 weeks in prison. In these high-reading cases, we build a robust mitigation package. We argue against a custodial sentence by presenting evidence of your character, your remorse, and your rehabilitation steps (e.g., voluntarily attending alcohol counselling before court).

The 25% Reduction: The DDRS Course

Even if you are banned, we can shorten the sentence. We request that the court allows you to take the Drink Drive Rehabilitation Scheme (DDRS) course.

• The Benefit:Completing this course reduces your ban by 25%.

• Example:A 12-month ban becomes 9 months.
• The Catch:You must ask for this at the sentencing hearing. If your solicitor forgets to ask, you cannot add it later. We ensure this request is always made.

Why Motoring Defence?

Conclusion

A drink driving charge is terrifying, but it is not a conviction until the court says so. Test the evidence. Challenge the procedure.
