Understanding the Legal Process of Breathalyzer Tests in Different Jurisdictions
The legal process surrounding breathalyzer tests can vary significantly depending on the jurisdiction. Two prominent regions in this regard are Texas in the United States and Canada, each with distinct procedures and requirements for roadside and police station testing. This article explores the differences and similarities in these processes, focusing on the legal standards and rights of individuals.
Process in Texas, USA
In Texas, when a suspect is arrested for DUI (Driving While Intoxicated), the process typically begins with a series of field sobriety tests. These tests are conducted to determine if there is probable cause to arrest the suspect for DWI (Driving While Impaired). If the suspect exhibits a minimum number of clues, indicating impaired driving, they are usually arrested for DWI.
Following the arrest, the arresting officer will read the suspect the DIC-24 form, which includes a request for a breath or blood test to determine the suspect's blood alcohol content (BAC). If the suspect consents to a breath test, they will be taken to a police station or county jail where a certified breath test operator will use an intoxalyzer instrument to administer the test.
It's important to note that portable breath tests, commonly used in other jurisdictions, are not utilized in Texas. This is because the court system does not consider the results of portable breath tests to be reliable evidence. Instead, the results of Standard Field Sobriety Tests, video evidence, and any breathalyzer or blood sample results are used.
Process in Canada
In Canada, the legal process for roadside testing is somewhat different. If a police officer suspects that a driver has consumed alcohol, they can require the driver to blow into an Approved Screening Device (ASD) at the roadside. This test is designed to provide a preliminary indication of the driver's BAC. If the driver's BAC is above the legal limit of 0.08, they can be arrested and taken to a police station for a formal breathalyzer test.
It's crucial to understand that the results from the ASD test can only be used to establish reasonable suspicion for an arrest. The results are not admissible as evidence in court proceedings. A true breathalyzer test, which requires the use of a larger, stationary instrument, is typically conducted at a police station and is the only type of test that can be admitted as evidence in court.
Challenges and Rights
While the roadside breath test can provide initial evidence for an arrest, there are rights granted to individuals who refuse to take the test. However, refusing to take a breath test can lead to consequences such as a temporary license suspension in some states, and the officer may request a telephonic search warrant for a blood test if they believe it will provide more definitive evidence.
It is generally easier to get a breath test result thrown out in court than a blood test, as a breathalyzer test is more susceptible to contamination and human error. Therefore, individuals should be aware of their rights and understand the potential consequences before deciding to refuse a test.
Conclusion
Both the Texas and Canadian systems have their unique processes for administering breathalyzer tests, each designed to ensure fairness and legal rigor. Understanding these differences can help individuals navigate the complexities of DUI charges more effectively. Whether it's a roadside breathalyzer or a breathalyzer administered at a police station, knowledge of the legal framework is crucial to protect one's rights and interests.
