DUI charges sometimes come about as a result of things that happened or things police found while a driver was at a drunk driving checkpoint. 

Such checkpoints involve police setting up camp on a road and checking the drivers who go through the checkpoint for signs of impaired driving. Based on what police observe regarding a given driver at a checkpoint, they might take additional steps such as asking the driver to take a breath test or perform field sobriety tests. 

Now, such checkpoints do not occur in all parts of the country. A little under one-fourth of states currently do not have drunk driving checkpoints performed within their borders. 

Where does Illinois currently stand when it comes to DUI checkpoints? It is among the states where such checkpoints are deemed legal and are performed. It is estimated that hundreds of such checkpoints are conducted in the state per year. 

When a driver here in Illinois is facing drunk driving charges in connection to things that happened at a sobriety checkpoint, certain things can end up being a very big deal in their case. This includes what kinds of evidence police obtained at the checkpoint regarding the driver and what they did to get such evidence. There are limits on what police can do to obtain evidence at DUI checkpoints. Whether these lines were crossed are among the things experienced criminal defense attorneys can investigate for drivers who have been charged with drunk driving in relation to a DUI checkpoint.
