You had just spent a nice day out on the boat, drinking a little beer, catching a few fish, and taking in some sun. As the sun started to set, you headed back to shore and loaded your catch in the back of the truck before heading home.
Field sobriety tests (FST) are used to determine if a driver may be impaired. It is important to understand that an FST does not determine if you are able to drive, it gives an officer probable cause to conduct other, more invasive tests. Without probable cause, it can be difficult for an officer to justify asking for a breath, blood or urine test.
