Can Your Medical Records Help Challenge a DWI Charge in New York?

A police officer may describe bloodshot eyes, poor balance, confusion, slurred speech, or difficulty following instructions as signs of intoxication. But what if a documented medical explanation accounts for what the officer observed?

In some New York DWI cases, medical records can provide important context for symptoms or behaviors that law enforcement attributed to alcohol or drug impairment.

Records alone do not automatically defeat a DWI charge, but they may help challenge assumptions made during the investigation and provide evidence supporting an alternative explanation.

What Can Medical Records Show in a DWI Case?

Medical documentation may show that a driver had a diagnosed condition, injury, or treatment history before the traffic stop.

Depending on the circumstances, records could provide information about:

• Balance or mobility limitations.
• Neurological conditions.
• Diabetes or blood sugar problems.
• Vision difficulties.
• Prior head injuries.
• Prescribed medications and known side effects.
• Recent medical procedures or treatment.

The relevance of those records depends on the particular observations police relied upon and whether the medical history helps explain them.

Medical Evidence May Put Field Sobriety Tests in Context

Field sobriety tests require drivers to perform physical and cognitive tasks under roadside conditions. Certain medical conditions or physical limitations may affect a person’s ability to complete those exercises even when alcohol or drugs are not responsible.

For example, records documenting an existing balance disorder, leg injury, neurological condition, or other physical limitation could become relevant if prosecutors later rely on poor field sobriety test performance as evidence of impairment.

Body camera and dash camera footage can also be important. Comparing what the video actually shows with documented medical limitations may provide a fuller picture than an officer’s written description alone.

Prescription Records Can Raise Different Questions

Medical records may also establish that a driver was taking a legitimately prescribed medication at the time of the stop.

That does not necessarily resolve the DWI allegation. Some prescription medications can impair driving, while others may cause physical symptoms that officers interpret as signs of intoxication without actually affecting driving ability.

A defense may therefore need to examine the medication, dosage, timing, side effects, and other available evidence rather than simply establishing that a prescription existed.

Timing and Consistency Can Affect the Value of the Records

Not every medical record will carry the same significance.

Records documenting a condition well before the DWI arrest may help establish that symptoms were not created as an explanation after the fact.

Treatment notes from around the time of the arrest may also provide information about the driver’s physical condition.

The defense may compare medical documentation with police reports, video footage, chemical testing, witness statements, and other evidence to determine whether the prosecution’s interpretation is consistent with the complete record.

The Officer’s Interpretation Is Not the Only Evidence

A DWI investigation often begins with an officer making observations within minutes. Medical records can sometimes provide years of context that the officer did not have at the roadside.
