Musings about San Diego DUI Checkpoint trailers

AR-150929933.jpg&maxh=400&maxw=667.jpeg

I was browsing the internet and read this article about a new DUI checkpoint trailer obtained by a law enforcement agency.  On the face of it a trailer at the checkpoint sounds like a good idea.  It saves times and wraps it all at the scene. The problem is part of the "system" involves very sensitive machines.  These machines measures someones blood alcohol from breath.  These are not supposed to moved around like a students laptop.  They are to be positioned in a facility usually at a police agency or jail.  

The result is faulty numbers.  Man and machine make mistakes.  Trying to make a device not intending to be mobile does not help the situation.  It is one of many things you have to examine in a DUI checkpoint case (especially with a trailer). Here is a article. ___________________________________________________________

In 2014, the Eureka Police Department was approved to use funds from a California Office of Traffic Safety (OTS) grant to purchase a new DUI Checkpoint Trailer. The new trailer has been delivered and is ready to be put to use.

The new trailer is replacing the old trailer which was also purchased with an OTS grant back in 1998. The new trailer is a self-contained mobile operations center, holds all equipment, and has additional lighting to better safeguard the officers in and around the checkpoint area.

DUI Checkpoints are designed to be a highly publicized deterrent to steer people away from driving impaired or while unlicensed. The Eureka Police Department plans to hold at least two DUI Checkpoints during the upcoming grant year which runs October 1, 2015 through September 30, 2016

It seems like a good time to refresh on your rights at a San Diego DUI Checkpoint. It is important for citizens to know their rights. As a San Diego DUI and Criminal defense attorney, I can tell you that most people do not use their rights when being investigated by the police. Most of the people want to be compliant and non-confrontational with the officer as possible in a San Diego DUI or San Diego criminal defense case. They feel if they are compliant the officer will let them go, usually because the person has never been in contact with police before when they are the ones being investigated. It may be you...a friend...or a loved one as the focus of a San Diego DUI or criminal defense investigation. You have to know and use your rights and be proud (and not scared) to use them.

One other point to stress....people sometimes say I do not have to be afraid if I did not do anything wrong. Well, it is not illegal to drink and drive. You cannot be impaired or have a blood alcohol level greater than .08%. Well, when you are on I-5 and the you tell the officer about the two blue moons you had at happy hour before you headed home...trust me...you are under .08% and not likely impaired...but...you will be throughly interrogated as well as delayed getting home for at least an hour. The officer will be eyeing you. Every stumbled word (because you are scared). Every delay in his instructions on an field sobriety test..the officer is chalking as you being guilty of a San Diego DUI. If the machine gives a bad reading (for a myriad of reasons) and you are heading to jail, car towed, license suspended, and will have to fight to prove the machine was in error.

Roadblocks are legal but as discussed below it must follow a specific set of criteria. Here is an illustration that may help you in a San Diego DUI checkpoint investigation.

The utilization of San Diego DUI 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. 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 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 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.

We can file the necessary legal motions to throw out the evidence collected following an illegal arrest. To allow the police to stop those persons that lawfully turn away onto a public street prior to entering a San Diego DUI checkpoint is clearly unduly invasive of the individual rights afforded to us by the U.S. and California Constitution. 

Another common problem associated with San Diego checkpoints is breath testing. The problem is that the tests are administered on a device that is carried in a trailer or mobile breath testing vehicle. In my experience these devices are routinely jolted, bounced, battered and generally abused given the their mobile environment. In many cases the device or machine was never approved to "go mobile" and challenges can sometimes be made on the reliability of the results on these grounds. Furthermore, deficiencies are often seen in the procedures utilized when administering the breath test, for example, Title 17 of the California Code of Regulations mandates that the individual being tested be continuously observed by the officer for a minimum of 15 minutes prior to the test, this is often overlooked in the DUI checkpoint context given the pandemonium that surrounds a sobriety checkpoint arrest.

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.
