Some people get arrested for driving under the influence (DUI) offenses after car crashes or targeted traffic stops. Others might be at risk of prosecution because they encounter mass enforcement checkpoints. DUI checkpoints , also known as sobriety roadblocks or safety checkpoints, are a common law enforcement tool in Virginia.
They allow local authorities to screen dozens of people for signs of intoxication while limiting the commitment of resources. What can drivers expect when approaching a DUI checkpoint?
Cursory screening is standard
For DUI checkpoints to be legal law enforcement tools, officers have to minimize the impact that they have on the general public. They generally perform a speedy initial screening with every driver who approaches the checkpoint to limit the inconvenience to the general public.
They ask a few questions and look for telltale signs of intoxication. Most drivers who approach a DUI checkpoint end up proceeding through without much delay.
Those who give officers reason to suspect them of intoxication may have to pull aside for additional screening. Officers may ask them to perform field sobriety tests or to submit to chemical testing. Some of the drivers selected for enhanced screening could face arrest and prosecution.
Not everyone arrested at a checkpoint is necessarily drunk. The confirmation bias of officers conducting a checkpoint might lead to assumptions that people are under the influence when they are not. Issues with testing procedures or devices could also lead to unfair arrests.
Learning more about sobriety checkpoints and other drunk driving law enforcement tools can be beneficial for motorists, especially those who regularly enjoy alcohol. Drivers arrested at checkpoints often need to develop highly-specific criminal defense strategies to avoid criminal convictions.
