Can You Be Charged for Drink Driving Without a Breath Test?

Drivers are typically charged with drink driving when the results of a breath test show that they are above the legal limit. However, this is not always necessary. The law allows the police to pursue a drink driving offence even when no breath sample is obtained. If a person refuses to provide a specimen, is unable to give a sample for medical or physical reasons, or is considered unfit through drink based on evidence of impairment, the police can still bring a charge. These cases can result in penalties such as a driving ban, an unlimited fine or in some cases a custodial sentence, depending on the circumstances and any previous convictions.

Below, JMW’s motoring law specialists explain the situations where a person can be charged with drink driving without a breath reading, what penalties you could face if you are found guilty, and how a motoring solicitor can defend your position.

When Can the Police Charge You Without a Breath Test?

A roadside test is the most common way for officers to assess whether a driver is above the prescribed limit. However, a breath test is not the only method the police can rely on to bring a drink driving charge. Under the Road Traffic Act, prosecution can follow when:

• The driver refuses to provide a specimen.
• The driver is physically or medically unable to provide a breath sample.
• The police rely on evidence of impairment rather than alcohol level.
• The driver is considered in charge of a motor vehicle while influenced by alcohol.

A court can treat these situations as seriously as driving with excess alcohol. The nature and circumstances of the incident will influence how the police proceed, as well as the sentencing guidelines applied if the case reaches court.

Is Refusing to Provide a Specimen a Criminal Offence?

Failing to provide a specimen is a separate criminal offence from drink driving. If the police suspect you have consumed alcohol and request a breath sample, refusing without a reasonable excuse will usually result in arrest and a charge brought through the courts.

The police can ask for two types of tests:

• A roadside test to establish reasonable suspicion.
• An evidential sample at the police station, which may be breath, blood, or urine.

Failing to provide an evidential sample is treated in the same way as driving above the legal alcohol limit. The penalties include:

• A driving ban of at least 12 months, increasing to three years with previous convictions.
• An unlimited fine.
• Up to six months’ imprisonment.

If the police cannot obtain a suitable breath sample, they may require:

• A blood sample, taken by a qualified medical professional.
• A urine sample, provided under supervision.

Refusing either form of specimen carries the same penalties as refusing a breath test. A conviction will appear on your driving licence and can have a significant impact on employment, insurance and travel.

Medical Reasons and Reasonable Excuses

There are limited situations where a person may be genuinely unable to provide a specimen. These cases must be supported by clear medical evidence and often require assessment by a doctor.

Examples of reasons that may be considered legitimate for failing to provide a sample include:

• Respiratory conditions that prevent a full breath sample.
• Conditions that affect bladder control and limit the ability to give a urine sample.
• Mental health conditions that prevent meaningful co-operation.
• Physical injuries that make testing impractical.

A reasonable excuse defence will be examined carefully by the police and the court. If the explanation is not supported by strong evidence, the driver can still face a conviction for failing to provide. It's important to seek the advice of an experienced motoring offence solicitor from the team at JMW if you have been accused of refusing to give a sample and believe you have a reasonable excuse. Our team can look at the circumstances and establish whether there was a valid reason for your inability to provide the sample.

Can You Be Charged Based on Behaviour or Evidence of Impairment?

The police do not always need a numerical reading to prosecute a drink driving offence. If an officer has reason to believe you are unfit to drive through alcohol, you may be charged based on:

• The manner of your driving.
• Your behaviour, speech or physical appearance.
• Admissions about consuming alcohol.
• Witness accounts at the scene of an accident.
• Footage from officers’ body-worn cameras.
• Field impairment tests.

In these cases, the allegation may be driving while unfit through drink rather than driving with excess alcohol. Although the offences differ, both can lead to penalties such as a driving ban and a fine.

Penalties for Drink Driving Without a Breath Test Result

Sentencing guidelines allow the court to impose severe penalties when a driver is accused of refusing to co-operate or driving while unfit. Outcomes may include:

• A lengthy driving ban.
• An unlimited fine.
• Community punishment.
• Up to six months’ custody for multiple ‘related’ offences.

Factors such as previous convictions, the risk posed to the public, involvement in an accident and conduct at the station can influence the sentence. Even a first-time offence can lead to consequences that affect employment, travel and insurance for years.
