Police DUI checkpoints are something that drivers should be aware of as we are seeing them more often. It is a systematic stop for vehicles this means the police can't use a checkpoint as a way of just stopping who they want. They can't in any way arbitrarily or just randomly stop a vehicle and pull it over in a checkpoint. It is a systematic stop in which everybody who goes through the checkpoint system's vehicle is stopped and obviously investigated with suspicion the driver has been driving under the influence of alcohol.

The traffic safety checkpoints are set up usually across busy cities where the police have convicted the most drivers who have been drinking alcohol. The emphasis of the checkpoints are to detect DUI violators which historically rise during the time of year near to the holiday season towards the end of the year for the Christmas period. When a driver is stopped at one of these DUI checkpoints, the driver will be asked politely for his or hers driver’s license, a valid proof of insurance for the car which they have been pulled over in and a current valid vehicle tag registration.

Police officers will usually be ready at both announced and unannounced locations around a city in what is a huge effort to reduce the horrific DUI related traffic accidents and fatalities which can cause a lot of knock on effects for the family's of those involved.

DUI roadblocks are actually temporary installations used by law enforcement agency's such as highway patrol officers and police officers to not only catch out the drivers who are under the influence of alcohol but to help to make the road a safer place to drive a car. This approach of policing the highway and the roads which citizens use as a way of getting from one location to the next was modeled off the back of the success of the roadside safety checks and license and the registration inspections which where very successful operations.

These checkpoints are usually set up late either at night or very early in the morning, which is actually when the highest percentage of drunk drivers is on the road usually traveling back from a party or some sort of social event where they have been consuming alcoholic beverages.
