Arrested for Driving Under the Influence in South Africa

Being arrested for driving under the influence of alcohol or drugs is one of the most common criminal charges laid against ordinary motorists in South Africa. A roadside breathalyzer that reads over the legal limit can turn a routine drive home into a night in a police cell and, later, a court appearance that may end in a fine, a criminal record, or imprisonment.

The process moves quickly and the choices made in the first few hours matter. The arresting officer’s procedures, what you say and do at the police station, and whether you have a lawyer at the bail hearing can all shape the outcome of the matter. This article explains, in practical terms, what happens after a DUI arrest and what your rights are at each stage.

The law comes mainly from section 65 of the National Road Traffic Act 93 of 1996 and from the arrest, detention, and bail provisions of the Criminal Procedure Act 51 of 1977. Your constitutional protections come from section 35 of the Constitution of the Republic of South Africa, 1996.

The Legal Limit and the Offence of Driving Under the Influence

Section 65 of the National Road Traffic Act 93 of 1996 makes it an offence to drive, or to occupy the driver’s seat of a motor vehicle with the engine running, while the concentration of alcohol in the blood or breath exceeds the prescribed limit. For an ordinary driver the limit is a blood alcohol concentration of 0,05 grams per 100 millilitres, or a breath alcohol level of 0,24 milligrams per 1 000 millilitres. For professional drivers the limit is far lower, at 0,02 grams per 100 millilitres of blood.

Section 65(1)(a) also criminalises driving while under the influence of intoxicating liquor or a drug having a narcotic effect. This means that even where a breath or blood reading is not taken, the State can prosecute on the basis of the arresting officer’s observations and field sobriety evidence. The two routes often run together in the same charge.

The offences most commonly charged are driving under the influence, alternatively driving with excessive blood or breath alcohol, and reckless or negligent driving where the driving itself was dangerous. Each carries its own penalties on conviction.

The Arrest: What the Police May and May Not Do

A metro police officer or South African Police Service member may stop a vehicle at a roadblock or on reasonable suspicion of drunk driving and require the driver to submit to a breathalyzer test. If the reading is over the limit, or if the officer forms a reasonable belief that the driver is under the influence, the driver may be arrested without a warrant. The arrest is carried out under the powers in section 40 of the Criminal Procedure Act.

Once arrested, you will be taken to a police station. There the police may ask you to provide a breath sample on an approved evidential breath tester, or to accompany a district surgeon or registered nurse to have a blood sample drawn. The blood sample must be taken within a set time of the alleged offence, and the chain of custody for that sample later becomes central evidence in the trial.

You are entitled to be treated with dignity and to be informed of the reason for your arrest. The police must record the time of arrest, the time of the test, and the procedure followed. Mistakes in this paperwork can be decisive later, which is why the docket should be examined by a criminal defence attorney as early as possible.

Your Rights Under Section 35 of the Constitution

Section 35 of the Constitution gives every arrested person a short list of rights that the police must explain in a language you understand. Section 35(1) gives you the right to remain silent, the right to be informed of that right and of the consequences of not remaining silent, and the right not to be compelled to make any confession or admission that could be used in evidence against you.

You also have the right to be brought before a court within 48 hours of arrest, or, if the 48-hour period ends after court hours, on the first court day after that. This is the practical expression of the 48-hour rule under section 50 of the Criminal Procedure Act, and it is the safeguard against being held indefinitely in a cell.

• Remain silent. You are not obliged to answer questions about the alleged offence beyond identifying yourself.
• Consult a lawyer. You may contact, and be visited by, a legal practitioner of your choice.
• Be informed of the charge. You must be told, in a language you understand, what you are alleged to have done.
• Be brought to court within 48 hours. Excluding weekends and public holidays, the police must deliver you to a court within this window.
• Humane conditions. You must be detained in conditions consistent with human dignity.

The Breathalyzer, Blood Test, and Refusal

Alcohol test results, specifically evidence of blood or breath alcohol concentration, is the centre of most DUI prosecutions. The breathalyzer used at the roadside is a screening device. The reading that matters in court is usually taken on an evidential breath testing instrument at the police station, or from a blood sample drawn by a medical professional.

Refusing to cooperate carries its own consequences. Section 65(5) of the National Road Traffic Act gives the court a discretion, where a driver refuses to submit to a test, to treat the refusal as prima facie evidence that the driver was over the limit. In practice, refusing does not make the case go away; it simply shifts the evidential burden and gives the State an additional ground on which to convict.

The defence of a DUI charge often focuses on the procedure around the test: whether the instrument was calibrated and operated correctly, whether the blood sample was taken within the permitted period, and whether the chain of custody for the sample was preserved. These are technical questions and they are best examined by an attorney who is familiar with the docket format.

Bail, the Docket, and the NPA Decision

After the arrest, the docket is compiled and sent to the National Prosecuting Authority for a decision on whether to prosecute. For a first offence, the prosecutor may in some instances agree to the matter being disposed of by way of an admission of guilt fine, which keeps the matter out of court but still leaves a criminal record. Whether that route is appropriate depends on the facts and the accused’s personal circumstances, and it should never be accepted without first taking advice.

Where the matter proceeds to court, release on bail is governed by section 60 of the Criminal Procedure Act. Bail can be set at the police station for less serious offences, or, where the offence is treated as serious, at the first court appearance. The court weighs the interests of justice, including the likelihood that the accused will stand trial, the gravity of the alleged conduct, and the risk to the public.

• Police bail. Available, in defined circumstances, for a first offender charged with certain offences, set by a senior officer at the station.
• Prosecutor-assisted bail. Granted at the first appearance with the consent of the public prosecutor, before the formal bail inquiry.
• Court bail. Determined by the magistrate after a section 60 inquiry, where the court weighs the interests of justice against the right to freedom.

Bail is not a fine and it is not a conviction. The amount paid is refunded once the matter is finalised, provided the accused attends every court date.

The Court Process and Possible Penalties

Once the NPA enrols the matter, it proceeds in the magistrate’s court. The State must prove the case beyond reasonable doubt. The accused may lead evidence, cross-examine the State’s witnesses, and challenge the admissibility of the breath or blood evidence. A plea of guilty, if entered, must be confirmed in the form prescribed by the Criminal Procedure Act.

On conviction for driving under the influence under section 65(2), the court may impose a fine or imprisonment, or both. A conviction also results in a criminal record, and the court may endorse or suspend the accused’s driving licence. Repeat offenders, and matters involving serious injury or death, attract far heavier sentences and are sometimes dealt with under reckless or negligent driving, or culpable homicide, charges.

The broader consequences of a conviction can be significant. A criminal record may affect employment, professional registration, travel visas, and firearm licensing. For these reasons it is worth taking the charge seriously from the moment of arrest, even where the reading is just over the limit.

Frequently Asked Questions

What happens after you are arrested for driving under the influence in South Africa?

After arrest you are taken to a police station, where you may be asked to provide a breath or blood sample. You must be informed of your rights under section 35 of the Constitution and brought before a court within 48 hours. The docket is then sent to the National Prosecuting Authority, which decides whether to prosecute and on what charge.

Can you refuse a breathalyzer or blood test in South Africa?

You can decline, but section 65(5) of the National Road Traffic Act allows the court to treat refusal as prima facie evidence that you were over the legal limit. Refusing does not end the case; it usually strengthens the State’s hand and may be raised separately at trial.

What is the legal alcohol limit for drivers in South Africa?

Under section 65 of the National Road Traffic Act 93 of 1996, ordinary drivers may not exceed a blood alcohol concentration of 0,05 grams per 100 millilitres, or 0,24 milligrams of alcohol per 1 000 millilitres of breath. For professional drivers the limit is 0,02 grams per 100 millilitres of blood.

Will a DUI conviction give you a criminal record?

Yes. A conviction for driving under the influence, or for driving with excessive blood or breath alcohol, results in a criminal record. The court may also impose a fine or imprisonment and may endorse or suspend your driving licence. Even an admission of guilt fine leaves a record.

Can a first-time offender avoid jail for a DUI in South Africa?

For a first offence with no aggravating features, the court often imposes a fine rather than direct imprisonment. Each case turns on the reading, the driving, any prior convictions, and personal circumstances. Early legal advice improves the prospects of a fair and proportionate outcome.
