Some Basic Points About DUI Roadblocks

Police departments in the Treasure Coast love DUI checkpoints. If they could afford the officer overtime and physical requirements, they would probably run checkpoints every weekend. But because of these costs, roadblocks usually only appear during holidays associated with drinking and driving, such as July Fourth and New Year’s Eve.

These checkpoints give police officers lots of powers that they do not usually have. So, DUI roadblocks must also meet some very specific requirements.

General Rule in Port St. Lucie DUI Stops

Typically, officers must have reasonable suspicion to detain motorists for suspicion of DUI. Under current law, this standard is very low.

There are actually two parts to a DUI stop. First, the officer must have reasonable suspicion to pull over the vehicle. In almost all cases, said reasonable suspicion is an unrelated traffic offense, such as speeding or failure to stop at a stop sign. Occasionally, Port St. Lucie officers pull over motorists because they receive a tip about a suspected drunk driver.

Next, the officer must have reasonable suspicion to administer field sobriety tests. Sometimes, the traffic stop plays a role here. For example, erratic driving sometimes indicates alcohol impairment. But generally, this second level of reasonable suspicion comes from facts that the officer observed (e.g. odor of alcohol) or statements the defendant made (e.g. “I only had one beer”).

But the reasonable suspicion rule does not apply to DUI checkpoints. Instead, these roadblocks must follow a separate set of rules.

Requirements for Port St. Lucie DUI Checkpoints

Current law on this topic is basically a compromise. Before the 1980s, officers could erect checkpoints any time, anywhere, and for any purpose, and it was legal. Then, the Supreme Court outlawed roadblocks altogether. Finally, in 1990’s Michigan State Police v. Sitz, the Justices allowed law enforcement agencies in Florida and elsewhere to use roadblocks in certain situations:

  • No Officer Discretion: Every aspect of the checkpoint, including the location, hours of operation, and manner of pulling over vehicles, must be made at the supervisor level. Officers on the scene can only change the conditions under specific circumstances.
  • Maximize Safety: The location and hours must be calculated to maximize safety for motorists. Officers would like to set up DUI checkpoints on interstates and other very busy locations, but these places are usually too unsafe.
  • Minimize Disruption: As a rule of thumb, any wait longer than two or three minutes is too long. This period includes both waiting in line to get to the checkpoint and the review itself.
  • Create Opportunity: The roadblock must be sufficiently advertised in advance, perhaps with signs like “DUI Checkpoint Ahead,” to give motorists the opportunity to turn around and avoid the checkpoint altogether.

In that last instance, if motorists turn around, they can expect police cars to follow them. For these officers to pull over these motorists, the reasonable suspicion rule applies.

Drivers have rights at DUI checkpoints. They do not need to answer questions or even roll down their windows. They do need to produce requested documents, which usually includes drivers’ license and proof of insurance. It’s also wise not to antagonize officers in this or any other situation.
