Drunk driving in South Africa carries up to 6 years’ imprisonment, fines up to R120,000, licence suspension and a criminal record that follows you into every job application and visa. But sentencing reality is more nuanced — and the difference between the worst outcome and a managed one is almost always what happens in the first days after arrest. Here is what you actually face, and what determines where you land.
The legal limits
Blood alcohol: 0.05g per 100ml for ordinary drivers, 0.02g for professional drivers (with a PrDP). Breath: 0.24mg per 1,000ml. Separate offences exist for driving under the influence (impairment, no reading needed) and driving over the limit (the reading itself). The State must prove the sample was lawfully taken — blood within two hours, by authorised personnel, with an intact chain of custody.
Sentencing in practice
First offenders without accidents typically face fines (commonly R2,000–R20,000 in the magistrates’ courts), wholly or partially suspended sentences, and sometimes community service — imprisonment is competent but reserved for aggravated cases: high readings, accidents, injuries, repeat offences. Repeat offenders and cases involving death (culpable homicide) face real custody. Every conviction, however light the sentence, is a criminal record.
Licence consequences
On conviction, the court must suspend your licence (first offence: minimum 6 months) unless circumstances justify otherwise — a discretion that must be argued with evidence: employment dependence on driving, no prior record, low reading. Professional drivers’ livelihoods die here, which is why the licence argument deserves as much preparation as the plea.
The criminal record problem
A DUI conviction records as a criminal record affecting employment screening, professional registrations, firearm licences, US and Schengen visas and emigration points. Expungement is possible only 10 years later if the fine was within thresholds. Diversion — where available — resolves the case without a conviction and is the single most valuable outcome for eligible first offenders.
Defences that actually work
Late blood draws (outside 2 hours weakens or destroys the presumption), chain-of-custody gaps between clinic and lab, uncalibrated or unverified breathalysers, unlawful stops and rights violations at arrest. These are technical cases; the State’s file frequently fails technical scrutiny. Never plead guilty at first appearance ‘to get it over with’ — that trade is almost always a bad one.
What to do after a DUI arrest
Exercise bail rights immediately (police bail is common for DUI), record everything you remember — times, medical staff, what was signed — and get representation before your first appearance. Early representations to the prosecutor resolve more DUI cases than trials do.
Frequently asked questions
Will I go to jail for my first DUI?
Rarely, absent aggravating factors — but you will get a criminal record unless diversion or acquittal intervenes. That record is the real penalty for most first offenders.
Can I refuse the breathalyser?
Screening refusal has consequences and blood can be taken lawfully regardless. The fight is almost never at the roadside — it’s about procedure afterwards.
Is there a difference between DUI and driving over the limit?
Yes — impairment (Section 65(1)) needs no reading, just evidence of influence; over-the-limit (65(2)/(5)) is about the number. Charges often plead both alternatives.
Can a DUI charge be withdrawn?
Frequently — where blood was late, the chain of custody is broken or calibration certificates are missing, representations succeed. That’s a legal review of the docket, not luck.
