Pulled Over for DUI in Bakersfield: What Officers Look for Before an Arrest

Most DUI cases in Bakersfield don't start with a breath or blood test—they start with a traffic stop. What happens in the first few minutes of that stop often determines whether an arrest follows.

Understanding what officers are trained to observe can help you make sense of what happened and why your case unfolded the way it did.

Why officers initiate DUI traffic stops

Officers may stop a vehicle for:

• Speeding or traffic violations

• Weaving or drifting within a lane

• Equipment issues such as broken lights

• Checkpoints or saturation patrols

A traffic stop does not automatically mean DUI—but it opens the door to further investigation.

Initial observations matter

Once stopped, officers look for indicators they associate with impairment, including:

• Odor of alcohol

• Bloodshot or watery eyes

• Slurred or slow speech

• Difficulty following instructions

These observations are subjective and can be influenced by stress, fatigue, or medical conditions.

Field sobriety tests are optional

Many drivers don't realize:

• Field sobriety tests are not mandatory

• Performance can be affected by nerves, injuries, or uneven surfaces

• Tests are designed to build probable cause, not to help you pass

Poor performance is often cited as justification for arrest.

Preliminary breath tests and arrests

In some situations, officers may request a preliminary breath test. Refusal or results above the legal limit may contribute to probable cause, but they are not the final word in a DUI case.

An arrest decision is often based on the totality of circumstances, not a single factor.

Probable cause can be challenged

A DUI lawyer may examine:

• Whether the stop was legally justified

• Whether observations were consistent or exaggerated

• Whether tests were properly administered

If probable cause was weak, evidence may be challenged or suppressed.
