Drunk driving crashes often leave behind two separate cases running side by side. The state pursues criminal charges against the impaired driver, while the injured person and their family have to build a civil case for compensation. The two processes overlap more than most people expect, and toxicology evidence sits right at the center of both.
How Blood Alcohol Evidence Gets Collected
When police respond to a suspected DUI crash, officers typically administer field sobriety tests and, when appropriate, a breath or blood test to measure blood alcohol concentration. That evidence becomes part of the criminal investigation, but it does not stay locked inside that case. Toxicology results, officer observations, and citation records can all be requested and used to support a civil injury claim as well.
Why the Criminal and Civil Cases Move Differently
The criminal case operates on its own timeline, driven by prosecutors and subject to different rules of evidence than a civil claim. A conviction is not required for a civil case to succeed, and a civil claim can often move forward well before the criminal matter is resolved. Evidence of impairment collected for the criminal case, though, tends to carry real weight once it makes its way into the civil claim.
What a Toxicology Report Actually Shows
A toxicology report documents more than a single blood alcohol number. It typically covers the time the sample was collected relative to the crash, the testing method used, and any other substances detected beyond alcohol. An Ashland drunk driving accident lawyer will want to understand exactly when a sample was drawn relative to the collision itself, since blood alcohol levels change over time and small details in the timeline can matter quite a bit.
Other Evidence That Supports a Toxicology Finding
Toxicology results rarely stand alone in a strong civil case. Several other pieces of evidence typically get gathered alongside it.
- Officer observations noted at the scene, including behavior and physical signs of impairment
- Surveillance footage from a bar, restaurant, or store showing how much a driver had consumed
- Receipts or server logs that may support a claim against an establishment that overserved a visibly intoxicated patron
- Witness statements describing the driver’s condition before or after the crash
Together, this evidence builds a much stronger picture than a single test result on its own. Andersen & Linthorst gathers all of it in parallel with the criminal investigation, working alongside investigators to build claims grounded in solid evidence.
Using This Evidence to Build a Civil Claim
Civil claims arising from drunk driving crashes often involve more than the driver alone. A bar or social host that continued serving a visibly intoxicated person may share responsibility under Oregon’s dram shop laws, which adds another potential source of recovery beyond the driver’s own insurance policy. Anyone injured by an impaired driver in Ashland can speak with an Ashland drunk driving accident lawyer to understand how the evidence in their case might support a claim.
