Scotland's Limit Is 22 — Not 35. One Drink Can Take Your Licence for a Year.

Since 2014, Scotland has run the strictest drink-drive limit in the UK: 22 microgrammes per 100ml of breath, 50 milligrams per 100ml of blood — a threshold official guidance says a single drink can breach. Cross it and Great Britain's mandatory minimum applies unchanged: 12 months off the road, three years for a repeat within ten, no job-hardship escape. The fiscal prosecutes, sheriffs and JPs sentence to £5,000 and six months, and the rehabilitation course can still buy a quarter off.

Drink Driving in Scotland — what to do right now

The two facts that matter tonight in Scotland. First: the limit is 22µg — effectively a zero-drinking rule when driving, and a morning-after trap without equal anywhere in Britain: at one unit cleared per hour, a modest evening still fails a 7am roadside test. Second: refusing the evidential specimens doesn't dodge anything — it's a separate offence carrying the same mandatory 12-month minimum, treated as seriously as high readings, with automatic High Risk Offender status on top. Comply with the procedure, say little beyond your identifying details (Scotland attaches no penalty to silence), and get the paperwork to a solicitor before your first calling in the JP or sheriff court. The course offer — up to a quarter off the ban — arrives once, at sentencing: walk in knowing your answer.


The law in Scotland: Drink Driving

The offence structure is Great Britain's, sharpened by Scotland's own limit. Driving or attempting to drive with excess alcohol under section 5 of the Road Traffic Act is strict liability against the Scottish figures — 22µg breath, 50mg blood, 67mg urine — set by the 2014 regulations and unchanged since. Driving while unfit (section 4) covers impairment by anything, prescription medicines included. Drug driving under section 5A arrived in Scotland in October 2019 with the same specified limits as England: near-zero for illicit drugs (cannabis 2µg/L, cocaine 10), therapeutic thresholds for medicinal ones, and the prescribed-as-directed defence. Being in charge while over is the lesser offence with the no-likelihood-of-driving defence; failing to provide specimens without genuine medical excuse carries everything the driving offence does.

Procedure runs through Police Scotland and the fiscal. Roadside screening on suspicion, a moving offence or any accident; arrest and the evidential station procedure — two breath specimens, lower reading counts, statutory warning that refusal prosecutes. Cases are reported to the procurator fiscal, who prosecutes drink and drug driving in the sheriff court (or JP court for the lowest readings) under summary procedure. Scotland's general protections travel with you: nothing beyond name, address, date and place of birth and nationality is owed, silence carries no adverse inference, and the interview cannot proceed without your consent unless your solicitor is present — though in excess-alcohol cases the reading, not the interview, is usually the whole case.

Sentencing pairs GB minima with Scottish machinery. The mandatory disqualification floor is identical: 12 months minimum on conviction for driving-or-attempting offences (drink, unfit, drugs, refusal), three years minimum for a second such conviction within ten — with no exceptional-hardship escape, and only narrow, driver-proved special reasons (spiking, genuine emergency, trivial distance). There is no Scottish sentencing-band table equivalent to England's; sheriffs sentence within statutory maxima — £5,000 fine and up to six months for the standard offence — guided by reading, circumstances and record, with Scotland's presumption against short custodial sentences pushing outcomes toward fines and community payback orders in all but the worst cases. The section 196 plea discount applies as everywhere in Scots law: up to about a third for the earliest plea.

The aftermath is GB-standard. The rehabilitation course operates in Scotland for drink offences with bans of 12 months or more: accepted in court, completed at least two months before the reduced ban ends, worth at least three months and up to a quarter off — with no equivalent for drug driving. High Risk Offender status attaches at 2.5 times the limit's blood equivalent (the same absolute figures as England: 87.5µg breath / 200mg blood), on any refusal, or two convictions in ten years — bringing the paid DVLA medical before relicensing. Endorsements ride the record for 11 years; insurers price them for years; interim disqualification from a first calling counts toward the total; and driving while disqualified is its own imprisonable offence prosecuted vigorously here.

The Scottish Limits

  • 22µg / 100ml breath · 50mg / 100ml blood · 67mg / 100ml urine — since 5 Dec 2014
  • Official line: 'just one drink can put you over' — effectively drink OR drive
  • Morning after: ~1 unit cleared/hour; an evening's drinking commonly fails a morning test
  • Drug limits (from Oct 2019): cannabis 2 · cocaine 10 · medicinal thresholds higher; prescribed-as-directed defence

Process & Penalties

  • Fiscal prosecutes; JP or sheriff court sentences — max £5,000 and 6 months for the standard offence
  • Mandatory ban: 12 months minimum · 3 years for a second drink/drug conviction within 10 (GB-wide s.34)
  • No exceptional-hardship escape; special reasons narrow and driver-proved
  • Plea discount up to ~1/3 at the earliest stage (s.196); presumption against short custody favours fines/CPOs

Refusal & Afterwards

  • Failing to provide = same minimum ban + automatic High Risk Offender status
  • Course (drink only): ≥3 months and ≤1/4 off — offered once, in court; complete 2+ months before the reduced end
  • HRO: 87.5µg/200mg equivalents, any refusal, or 2-in-10 → paid DVLA medical before relicensing
  • Endorsement 11 years; interim ban credited; driving while banned = imprisonable

The Border Changes the Verdict: Legal in Carlisle, Criminal in Gretna

Thirty-five microgrammes is a lawful drive in England; twenty-three is a conviction in Scotland. The A74(M) crosses that line in minutes, and every year drivers who "had one with dinner" — lawfully, by the standards of the country they woke up in — lose Scottish licences to arithmetic they never thought about. The morning-after maths is crueller still: clearing one unit an hour, a Friday night that ends at midnight can leave a Scottish driver over 22µg until mid-morning Saturday, facing the same mandatory year off the road as a closing-time drunk. There is no partial credit for nearly-legal: 23µg sentences under the same statute as 90. The only safe Scottish rule is total separation of drinking nights from driving mornings — and when it's already too late for prevention, preparation: the course, the plea timing and the paperwork triage are where months of licence get saved. Our free line runs any hour; the £145 consultation scripts your hearing.


Likely outcomes & penalties

Scottish drink-driving outcomes are compressed by the low limit and the fixed minimum — the variance lives in fines, course uptake and the rare defences. Realistic paths under current law; not promises, and we are not a law firm.
First offence, modest reading
Summary conviction, income-scaled fine within the £5,000 maximum, the mandatory 12-month ban — reduced up to a quarter by the course — and an early-plea discount on the financial side. Scotland's presumption against short custody keeps first offences overwhelmingly non-custodial.
High readings or aggravation
Crashes, passengers, terrible readings: community payback orders and, in the worst cases, custody within the six-month summary maximum — with bans stretching well past the floor and HRO status attaching from the 200mg blood equivalent. Solemn escalation is reserved for death and injury offences.
Refusal
Sentenced like the serious end regardless of any hypothetical reading, same minimum ban, automatic HRO — and in Scotland the refusal case is usually evidentially simple for the Crown. Genuine, evidenced medical incapacity is the only recognised excuse.
Drug driving
The 2019 limits make detection mechanical; penalties mirror drink driving with no course reduction available. Prescribed medicines taken as directed defend the limits charge but not actual impairment. Repeats within ten years — drink priors included — trigger the three-year minimum.

Mistakes to avoid

⚠️
Applying English arithmetic — "a pint is fine" is a Carlisle rule; at 22µg, Scottish enforcement treats a single drink as a gamble and the morning after as its richest hunting ground.
⚠️
Refusing the specimens — the same minimum ban arrives anyway, sentencing assumes the worst, and the HRO medical gate attaches automatically; genuine medical incapacity is the only excuse that survives.
⚠️
Letting the course offer pass at sentencing — it's made once; a quarter of a year's ban evaporates for want of a prepared "yes".
⚠️
Arguing hardship against the mandatory ban — job loss is legally irrelevant to it; channel that energy into the fine, the course and the calendar instead.
⚠️
Missing the special-reasons window — spiked drinks and genuine emergencies must be raised and proved at sentencing with evidence, not mentioned in mitigation as an afterthought.
⚠️
Driving before the licence actually returns — after longer bans and for HROs, the DVLA process (not the ban's end date) controls; jumping it is an imprisonable fresh offence.

FAQ — Drink Driving in Scotland

How much can I actually drink and drive in Scotland?

Treat the honest answer as none. The limit — 22µg breath, 50mg blood — sits low enough that official Scottish guidance says a single drink can breach it, and individual variation (weight, food, sex, stress) makes every conversion chart a lottery ticket. Enforcement reflects the policy: Scotland wanted separation of drinking and driving, and its courts deliver the same mandatory year's ban at 23µg as at 90. The design is the message — if you'll drive, don't drink.

Why is the morning after such a problem here?

Because arithmetic doesn't sleep. The body clears roughly one unit an hour — nothing accelerates it — so six units finishing at midnight still leaves alcohol aboard at 6am, and against a 22µg limit that's frequently enough. Police Scotland runs morning enforcement for precisely this reason, school-run and commute included. The practical rule: count units, count hours, and when the sums are close, they're not close — drive later or not at all.

What will I actually get for a first offence?

Expect summary conviction in the JP or sheriff court: a fine scaled to your means within the £5,000 maximum, the mandatory 12-month disqualification (less up to a quarter for the course), and an endorsement that rides your record for 11 years. Custody for a bare first offence is rare — Scotland's presumption against short sentences plus an early plea (worth up to a third under section 196) keeps outcomes financial. Aggravation — a crash, passengers, a dreadful reading — moves everything upward.

Does Scotland use England's sentencing bands?

No. England's magistrates read from published reading-by-reading tables; Scottish sheriffs and JPs sentence within the statutory maxima on ordinary principles — reading, circumstances, record — without a Scottish Sentencing Council guideline for this offence. The statutory floor is identical (12 months minimum, three years for repeats), so outcomes converge in practice, but Scottish mitigation is advocacy rather than table-reading — which is exactly where prepared representation earns its fee.

Is the rehabilitation course available in Scotland?

Yes — the scheme is Great Britain-wide. For drink offences carrying bans of 12 months or more, the sentencing court may offer the course: accept it there and then (the offer isn't repeated), complete it with an approved provider at least two months before the reduced ban would end, and the disqualification shrinks by at least three months and up to a quarter. It doesn't exist for drug driving. Walk into court already resolved to say yes.

What happens if I refuse the test in Scotland?

The same architecture as everywhere in Britain, with Scottish prosecution: refusing the evidential specimens without genuine medical excuse is its own offence carrying the identical mandatory minimum ban, sentencing that assumes the serious end, and automatic High Risk Offender status — the paid medical before any licence returns. The roadside screening refusal is a lesser, separate matter. Nothing about Scotland's silence protections extends to specimens: the right to say nothing is not a right to blow nothing.

Do Scotland's silence rules help me here?

At the margins. You owe police only your identifying details, no adverse inference attaches to silence, and interviews need your consent or your solicitor — all real protections. But excess-alcohol prosecutions are built on the certified reading, not the interview: the machine talks even when you don't. Where the general protections genuinely bite is the surrounding case — disputed driving, in-charge scenarios, post-incident drinking — where what you don't say stays truly cost-free while the defence is prepared.

What are the drug-driving rules in Scotland?

Since October 2019, the specified-limits offence operates here with the same numbers as England: near-zero thresholds for illicit drugs (cannabis's THC at 2µg/L catches use many hours old; cocaine at 10), therapeutic levels for medicinal drugs, and a defence for prescriptions taken as directed — though actual impairment remains chargeable regardless. Penalties track drink driving: the mandatory year minimum, £5,000/six-month maxima — with no course reduction, and drink priors counting toward the three-year repeat minimum.

Can special reasons save my licence?

Rarely, and only with work. Special reasons attack the disqualification, not the conviction: classically drinks spiked without your knowledge or suspicion (expert evidence on what the lacing added), a genuine emergency with no alternative, or a trivially short movement without danger. The onus is yours, the standard is proof, and Scottish courts apply it as sparingly as English ones. Exceptional hardship — the job-loss argument — has no application to this ban at all. If your facts genuinely fit, build the evidence before sentencing day; it cannot be retrofitted.

When and how do I get my licence back?

Bans over 56 days require applying for a new licence before driving — DVLA writes as the end approaches. High Risk Offenders (the 200mg-equivalent readings, any refusal, or two convictions in ten years) must first pass the paid DVLA medical, blood analysis included, on the department's timetable rather than the ban's. Complete the course on schedule, sort insurance honestly (11-year endorsement, declarable while unspent), and never drive in the gap — Scottish courts imprison for driving while disqualified with grim regularity.

Is this a law firm? Is the call really free?
