One of the most common things that police do to determine if someone is under the influence is to give them a breath test. This may be done after that individual has already gone through field sobriety tests or provided other indications that they may be impaired.
In a lot of cases, both the police officers and these individuals will just accept the results. But that’s a dangerous thing to do, as studies have found that they are often highly inaccurate. People just aren’t sure how the tests work or what could have gone wrong, so they assume the machine is correct. This could lead to a conviction that is undeserved.
Why are there inaccurate results?
In some cases, you may just have defective devices. A breath test is just a tool that the police can use. Like any other tool, it could be defective or there could be some sort of issue that prevents it from working correctly.
Another problem is when the police don’t calibrate the breath tests frequently enough. This has to be done to make sure that they’re working. If the devices have been neglected for a long stretch of time, that means that any results that they give are somewhat suspect.
Finally, there are instances when the officer administers the test incorrectly. They may be in a hurry or they may not have been trained properly. If they make a mistake, that means the results are not going to be reliable, either.
If you’re facing DWI charges and you suspect that the evidence against you may not be accurate, you need to know about your legal defense options.
