DWI/ DUI has become very prevalent, so law enforcement officers are quick to pull over suspicious drivers for a DWI/ DUI investigation. Oftentimes, officers can be a little too eager to arrest someone for intoxicated driving. If you’ve been arrested on charges of DWI/ DUI, you may have more grounds for defense than you realize.


Before an officer can make a DWI/ DUI arrest, he or she must have valid grounds to pull the suspect over for an investigation. Officers may not pull someone over “just because” they feel like it; they must have a valid reason to believe that you may be intoxicated. Witnesses can call in tips to the police department when they see a suspected drunk driver, which allows an officer to make a lawful police stop. Otherwise, an officer can only pull you over if they witness signs of intoxication themselves. These signs can include:

  • Failure to maintain lane
  • Excessive speed
  • Ignoring traffic signs and signals
  • Driving without headlights
  • Any other unusual driving behavior

If you were pulled over by an officer who had no grounds to do so, a skilled DWI Lawyer can build a strong case in your defense.


You could also have grounds for defense if your arresting officer made a mistake during the investigation. Standard field sobriety tests (SFSTs) are often used by officers to test your motor skills and divided attention abilities. Tests such as the walk and turn, following the officer’s finger with your eyes, or standing on one leg while counting out loud can help an officer determine whether or not you are truly intoxicated. These tests must be instructed properly and administered by the police officer with precision or the results are not reliable.  In addition, these tests can be affected by fatigue, nerves, and preexisting medical conditions. An officer must take great care to conduct these tests correctly in order to make an accurate judgment of your level of intoxication.  Jonathan B. Manley has been trained by senior police officers on the proper method to instruct and administer these tests and has the experience to challenge them in a courtroom.

Blood alcohol concentration (BAC) tests can also be mishandled by an officer. Breathalyzer machines are delicate and must be properly calibrated before each and every use. If your officer failed to calibrate the machine, give you proper directions, or administer the breath test correctly, then the readings could result in a false positive. Even a blood test can result in a false positive if it is mishandled or contaminated in the lab.
