Checkpoint FAQs

Q: What is ENDUI?
A: ENDUI is a program of the Oklahoma Highway Safety Office. Funds for equipment, personnel overtime, and other costs are funded by an impaired driving grant from the National Highway Traffic Safety Administration (NHTSA).

Q: Are checkpoints legal?
A: Checkpoints are legal through the Supreme Court decision in Michigan State Police v. Sitz that explains the limited scope of detention is allowed due to the severity of the DUI problem. It is our top priority to keep everyone safe while on Oklahoma’s roadways. Read more about this decision here: http://bit.ly/2pup9FO

Q: What do they look for when stopping a vehicle?
A: Law enforcement is trained to look for specific clues that a person may be impaired. This includes alcohol, marijuana, prescription medication, and other drugs. If law enforcement official suspects a person may be impaired, they are moved to a secondary screening area where the standard field sobriety test can be given and further investigation can be completed.

Q: Why isn’t every car on the road being stopped?
A: When a checkpoint is set up, only a certain number of vehicles will fit inside the checkpoint. Once the area is full (usually 5 or 6 vehicles), other traffic is allowed to pass. Don’t worry though, with each checkpoint there is a saturation patrol in the area.

Q: What is a saturation patrol?
A: A saturation patrol means there are a high number of officers, deputies and/or troopers in the area around the checkpoint. These law enforcement officials are looking for people who may be driving impaired, attempting to avoid the area of the checkpoint, or violating other traffic laws. If a law enforcement official suspects someone is breaking the law, they must have probable cause to initiate a traffic stop.

Q: Why do we need these checkpoints?
A: Simply put, impaired driving is a big problem across the state. Check out these numbers showing the extent of the problem:
