Are breath-test results always accurate?
Some courts allow the defendant in a drunk-driving case to challenge the scientific accuracy of breath tests in general, whereas others may allow challenges based on the particular circumstances of a test, such as improperly calibrated equipment or inadequately trained officers. If the test results are inadmissible or can be challenged, the case will probably have to be proven based on other evidence, such as eyewitness testimony and field-sobriety test results.
