Can You Be Charged If You Refuse a Saliva Sample?

Can You Be Charged If You Refuse a Saliva Sample

Driving under the influence of alcohol or illicit drugs is a serious offence that can have severe consequences for both the individual and the community. To combat this issue, law enforcement agencies employ various methods to identify and prosecute individuals who pose a risk on the roads.


One such method is the use of saliva tests to detect the presence of drugs in a driver’s system. In New South Wales, refusing a saliva test can have legal repercussions, and understanding the implications is crucial for every motorist.

The Significance of Saliva Tests

Saliva tests have become an integral tool for law enforcement in their efforts to combat drink driving and drug driving offences. Unlike traditional methods such as breathalyser tests that primarily focus on alcohol, saliva tests can detect the presence of a wide range of illicit drugs, providing a more comprehensive assessment of a driver’s impairment level.


When a police officer suspects a driver may be under the influence, they have the authority to conduct a roadside saliva test. This non-invasive procedure involves the driver providing a sample of saliva, which is then analysed for the presence of drugs. If the test is positive, it can lead to serious legal consequences.


Refusing or Failing a Saliva Test


In NSW, as in many other jurisdictions, refusing to undergo a saliva test is not taken lightly by law enforcement. When a driver refuses to provide a saliva sample, they may face charges that are distinct from those related to the actual offence of driving under the influence.


The law in NSW empowers police officers to charge individuals who refuse to comply with a saliva test. Refusing the test is considered a separate offence, and the penalties for such refusal can be significant. It’s important to note that these penalties can apply even if the driver is later found not guilty of the primary drug driving charge.


Charged with the Offence of Refusing a Saliva Test


When a driver is charged with refusing a saliva test, they may find themselves entangled in a legal process that involves defending against both the initial suspicion of drug driving and the subsequent refusal to comply with testing. The charges related to refusing a saliva test are serious and can result in substantial consequences.


One of the potential consequences of refusing a saliva test is the imposition of penalties similar to those for a drug driving offence. These penalties may include fines, disqualification of the driver’s licence, and even imprisonment in certain cases. The severity of the penalties can vary based on factors such as the driver’s history of similar offences and the specific circumstances surrounding the refusal.

One of the most significant repercussions of refusing a saliva test is the potential disqualification of the driver’s licence. In NSW, licence disqualifications are common penalties for a range of traffic offences, including both drink driving and drug driving.


The disqualification period imposed on a driver found guilty of refusing a saliva test can vary depending on the circumstances and the driver’s history. For a first-time offender, the disqualification period may be less severe than for someone with a history of similar offences. However, even a first-time offender may face a significant period of disqualification, impacting their ability to drive legally.


Tests the Police Use and Their Accuracy


It’s essential for drivers to understand the tests the police use and the accuracy of these tests, especially when facing charges related to refusing a saliva test. Saliva tests are designed to detect the presence of specific substances, including illicit drugs, in a driver’s system. These tests are backed by scientific research and are generally considered reliable when administered correctly.


However, like any testing method, saliva tests are not infallible. There have been instances of false positives or challenges to the accuracy of test results. It is crucial for individuals facing charges related to refusing a saliva test to consult with legal professionals who can assess the specific circumstances surrounding the test and potentially challenge its accuracy in court.


The 24-Hour Rule and the Sample of Breath


In NSW, drivers are subject to the 24-hour rule, which allows police officers to request a sample of breath from a driver within 24 hours of being stopped for a traffic offence. This includes situations where a driver has refused or failed a saliva test.


If a driver refuses a saliva test but is subsequently required to provide a sample of breath within the 24-hour period, it is essential to comply with this request. Refusing to provide a breath sample within the specified timeframe can lead to additional charges and further complicate the legal proceedings.

Can You Be Charged For Refusing a Saliva Test?

In addition to the offence of refusing a saliva test, individuals may find themselves charged with the primary offence of driving under the influence of drugs. A positive saliva test result can serve as evidence in support of these charges, and the legal consequences can be severe.


Being charged with driving under the influence of drugs carries penalties that may include fines, licence disqualification, and even imprisonment, depending on the nature and severity of the offence. It is crucial for individuals facing such charges to seek legal representation to navigate the complexities of the legal process and mount a robust defence.


Accordingly, refusing a saliva test is a separate offence that can result in significant legal consequences, including fines, licence disqualifications, and potential imprisonment. Understanding the implications of refusing a saliva test, as well as the accuracy of the tests themselves, is crucial for individuals facing such charges.


Drivers should be aware of their rights and responsibilities when stopped by police officers, especially in situations involving suspicion of drug driving.


Seeking legal advice and representation is essential for those charged with refusing a saliva test, as a skilled criminal defence lawyer can help navigate the legal process, challenge test results when appropriate, and work to achieve the best possible outcome for the individual involved. Ultimately, being informed and proactive is key to facing the legal challenges associated with refusing a saliva test in NSW.
