Human errors, technological errors, and violations of constitutional rights can all be grounds for challenging the evidence in a Fort Worth DWI case. Whether law enforcement officers improperly administer tests or lack reasonable suspicion to detain someone, errors can invalidate the evidence. Skilled legal counsel may be able to bring these inaccuracies and errors to light and fight for a positive resolution to DWI charges.

Various grounds may exist for raising defenses to and undermining the credibility of the evidence against you. Getting legal advice from the outset of your case may be the most effective way to defend yourself and protect your rights.

Human Errors and Evidence in DWI Cases

Although law enforcement officers receive training on properly conducting traffic stops and administering tests to measure intoxication, they may have little experience carrying out these activities. As a result, police officers may make mistakes in administering and interpreting field sobriety tests or roadside breath tests.

Likewise, police officers may fail to complete all required aspects of a DWI traffic stop, investigation, and arrest. For example, officers may provide the wrong test instructions fail to wait the required amount of time before administering a breath test. These situations may lead to evidentiary challenges in Fort Worth DWI cases.

Technological Errors in Fort Worth DWI Cases

Police officers commonly use portable breathalyzer devices to measure blood alcohol content (BAC) during traffic stops. When officers fail to maintain these devices, properly calibrate them, or fail to ensure that the driver’s breath properly registers, mechanical failure can lead to inaccurate and inconsistent test results. When an arrest relies on a driver’s BAC level, the state must have a reliable and correct measurement to prosecute the case successfully.

Likewise, lab technicians use machines to process blood samples and test for levels of alcohol and drugs. When these machines malfunction, or when a lab mixes up blood samples from different individuals, test results can be inaccurate. These situations can also lead to a criminal defense attorney challenging the evidence in a Fort Worth DWI case.

Constitutional Rights in DWI Cases

The U.S. Constitution guarantees individuals the right to be free from unreasonable searches and seizures. When law enforcement officers stop drivers whom they suspect are intoxicated, they must have reasonable suspicion to do so. They also must have probable cause to initiate an investigation and arrest a driver for DWI.

Furthermore, law enforcement officers may fail to give statutory warnings that are necessary to an arrest or skip procedural safeguards designed to protect the constitutional rights of individuals whom they are accusing of crimes. For instance, they may fail to warn drivers of the consequences of refusing a breath or blood test. All these errors can lead to a judge throwing evidence out of court.
