DUI Evidence: Police Investigation in DUI Cases

Most DUI arrests follow a predictable pattern. The police officer makes the stop or comes into contact with the suspect, questions are asked, physical observations are made, field sobriety tests are given, and then an arrest is made or the person is allowed to drive away.

It is important to understand what evidence police can use against you in a DUI case.  Evidence can include video taken from the arrest and even your actions before the arrest.  Learn what your rights are when you are pulled over or have been stopped a DUI checkpoint as well as how it differs depending on your locale.  A majority of evidence in DUI cases come from chemical tests performed on the suspects. The tests can come in a variety of formats and some tests hold up stronger in court than others.  Identifying each tests specific purpose and knowing which to take can be crucial in your case.  Every case will also have a witness, usually the police officer, which will testify to corroborate the evidence.

This section explains in great detail what a DUI officer is looking for in the various phases leading up to arrest.
