San Diego DUI Checkpoint - 11 arrested downtown

11 arrested at downtown DUI checkpoint

SAN DIEGO (CNS) – Eleven motorists were arrested on suspicion of driving under the influence of alcohol and 12 vehicles were impounded during an overnight driver’s license/sobriety checkpoint in downtown San Diego, a police officer said Saturday.

The checkpoint in the 1500 block of First Avenue began at 10:47 p.m. and ended Saturday at 3 a.m., said San Diego police officer Mark McCullough.

McCullough said 1,671 vehicles passed through the checkpoint, with 1,031 of those vehicles being screened by officers. Twenty motorists were detained for a further evaluation of their sobriety.

This is an example of San Diego drivers have to be careful.  A San Diego DUI from a checkpoint must be reviewed by a private attorney who knows the about checkpoints.  As a former prosecutor, I have dealt with a countless number of checkpoint cases.

The utilization of San Diego DUI or sobriety checkpoints has proliferated in the last few years due in large part to huge amounts of State grant money flowing into local city coffers from San Diego DUI fines and penalty assessments from convictions in Court. Police have also used saturation patrols as a way to ferret DUI drivers.  While the use of these types of law enforcement tools is generally regarded as comporting with Constitutional proscriptions, their use is not always legal. In the seminal case within the context of sobriety roadblocks, Ingersoll vs. Palmer, the United States Supreme Court handed down guidelines that must be complied with in any particular law enforcement initiated checkpoint. Among the factors are:

  • The degree of discretion left to the individual officer in the field
  • The specific location chosen for the roadblock
  • The time and duration of the roadblock
  • The standards set by superior officers
  • Was advance notice given to the general public
  • Was advance warning given to approaching motorists
  • Adherence to recognized safety conditions
  • The length of time each motorist is stopped and detained.

When challenging a San Diego DUI checkpoint each of the above factors is considered by the criminal Court Judge hearing the motion. In San Diego County the police use sobriety stops very heavily. It is not uncommon on any given weekend to see local police setting up a drunk driver roadblock in such places as Pacific Beach (PB), the Gaslamp area of Downtown, Poway, post-Chargers game, etc.  As the holidays are coming up, there will be more check points throughout San Diego County.

As a local attorney who has defended thousands of DUI cases, Mark Deniz can help evaluate whether your individual rights were violated. 

One very common problem with San Diego DUI checkpoints in San Diego DUIs is the stopping and detaining of drivers who simply turn off and avoid going thru a police initiated roadblock. Simply making a turn to avoid the checkpoint is not in itself illegal nor does it form the basis to stop and detain a motorist. If you or someone you know was stopped by the police under this type of scenario, contact Mark Deniz immediately.

One thing is true, the intrusion imposed upon the general public by the use of San Diego DUI checkpoints is very great and should be allowed, if at all, in very limited circumstances. If you or someone you love has had the unfortunate circumstance of being caught up in this type of possible illegal conduct by the police we urge you to call San Diego DUI attorney Mark Deniz for a free initial case evaluation at (858) 751-4DUI (4384).
