There are some situations in which the driver did not actually see the person driving but the suspect is still arrested and charged with DWI / DUI. Once again, the officer will have to document reasons for the arrest and the charge. Examples of this type of situation may be:nnAutomobile accident – If you have been involved in an accident the officer may conduct field tests to determine if you have been using alcohol or drugs in order to charge you with DWI / DUI.nCall From a Witness – If a credible witness calls the local authorities and accurately describe your driving in a manner that causes officers to feel you are in danger of harming yourself or others, you may be stopped and questioned.nParked Vehicle – There have been instances in which people were found passed out, behind the wheel of their parked cars, by officers. Pennsylvania and New Jersey have laws that allow officers to question you and possibly arrest you based on the fact that you have the potential and the access to use the vehicle.nnAs you can see there is a strong burden placed upon officers to provide sufficient reasons for stopping individuals in the first place. If an officer should mishandle any of the steps involved with proving you were under the influence of a drug or alcohol, it is possible to win your case. This is yet another reason why people should contact a local DWI / DUI attorney as soon as they have been arrested.
