Fresno DUI Checkpoints
Central Valley Sobriety Checkpoints
California law enforcement use sobriety checkpoints as a way to discourage
drivers from driving under the influence (DUI). Under the California Vehicle
Code, the legal limit for intoxication is a blood alcohol concentration
(BAC) of 0.08 percent. If the police find that your BAC is 0.08 percent
or higher, you will be arrested for a DUI. For driver's under the
age of 21, that limit is only 0.01 percent BAC.

California's Sobriety Checkpoint Policy
A DUI checkpoint is generally established on a public highway or road so
that law enforcement can check drivers to see if they are driving while
intoxicated. Often times, sobriety checkpoints are set up on weekend evenings,
or during the holidays. The Fourth of July, New Year's Eve, and Thanksgiving
are popular DUI checkpoint holidays. These checkpoints may also be set
up to coincide with a public event where alcohol may be served.
Field Sobriety Tests (FST)
When police suspect a driver might be impaired, they will request that
the driver use a breathalyzer in order to determine their BAC. Law enforcement
will also have the driver conduct any number of field sobriety tests (FSTs)
in order to determine the intoxication level of the driver. Some of the
FSTs may include the following:
- one-leg stand test;
- walk and turn test; and the
- horizontal gaze nystagmus (HGN) test.
By observing a driver's actions during these FSTs, the police officer
will attempt to gauge the driver's balance, coordination, dexterity,
and memory recall. These factors can be influenced by alcohol, and the
amount of alcohol consumed can affect a person's ability to perform
these tests. Officers in Fresno will use the results of their investigation
as justification to make a DUI arrest.
Public Notice Before Starting a Sobriety Checkpoint
Public notices are generally required before beginning a sobriety checkpoint.
This is so that residents of the city of Fresno can be alerted about the
upcoming checkpoint. The state of California maintains that the primary
objective behind sobriety checkpoints is more to discourage people from
drinking and driving rather than as a way to catch drunk drivers. However,
sobriety checkpoints end up doing both.
A side effect of sobriety checkpoints, is that they help police to apprehend
other offenders in and around Fresno. A checkpoint may result in the police
citing people for other traffic violations, or arresting people who are
driving without a valid license, or for other
The state provides law enforcement guidelines for setting up and conducting
a sobriety checkpoint. For example, once a location is approved, there
must be a formula in place to dictate which vehicles will be stopped and
investigated. Random vehicle stops are not permitted. The police can not
stop cars based on arbitrary reasons or preconceived ideas.
Public Safety & DUI Checkpoints
Sobriety checkpoints must also be conducted in locations which ensure public
safety. This includes flashing lights, clearly visible police vehicles
and police officers, and proper warning signs. If an officer is conducting
a breath test of FST, they can only detain the person for as long a time
as necessary to determine whether the driver demonstrates signs of intoxication.
If the driver does not show signs of impairment, they are to be timely
released and allowed to go about their business.
A California Supreme Court decision has held that a driver who makes an
attempt to avoid a sobriety checkpoint can not be stopped based solely
upon their attempt to avoid the checkpoint. Such a driver can only be
stopped if a they committed a traffic violation.
