Even though they are legal, OVI checkpoints are always going to be somewhat controversial. At a checkpoint, the police may stop every single driver to see if they're intoxicated before allowing them to continue. This is far different than normal traffic stops, which require the police to have a reason to pull the car over. Many drivers think it is unfair that the police can pull everyone over, even without cause, at a checkpoint.
Controversial or not, these keep happening. A recent checkpoint in Ohio saw multiple arrests.
The checkpoint was set up on Saturday, August 10. It was manned by officers with the Ohio State Highway Patrol. They started right around 10 p.m. and continued until 2 a.m., seeing as how a high percentage of drunk driving accidents take place at night.
Overall, the officers stopped about 400 cars. They asked 23 of the drivers to pull aside for "additional assessments." In 19 of those cases, they wanted to see if the drivers had been drinking alcohol. They made a total of four OVI arrests -- or 1% of the total drivers that were stopped. They also arrested two more individuals for related charges. Two others faced arrest, as well, one for a weapons charge and the other for drug paraphernalia.
As you can see, though the primary focus of a checkpoint is to look for those who have been drinking, that is not all that the police consider. Once they have a car stopped, they think about any reason to take the driver to jail. It's critical that these drivers know what legal options they have.
