Yes — in some cases, a person can be convicted of DWI in Arkansas even without a breath or blood test. A chemical test often makes the state’s case stronger, but it is not the only way prosecutors try to prove impairment.
That said, cases without a chemical test are often more defensible, because the state usually has to rely heavily on officer observations, field sobriety tests, and circumstantial evidence.
Two Different Ways the State Tries to Prove DWI
Most people think a DWI case depends entirely on a BAC number. In reality, DWI cases generally fall into two proof categories:
- “Per se” DWI: the state proves your BAC was at or above the legal limit.
- “Impairment” DWI: the state claims you were intoxicated or impaired based on observations and circumstances, even without a BAC number.
If there is no chemical test, the state usually proceeds under an impairment theory.
What Evidence Prosecutors Use When There Is No Breath or Blood Test
When there is no chemical test, prosecutors typically try to build the case using some combination of the following:
1. Officer Observations
- Odor of alcohol or marijuana
- Red or watery eyes
- Slurred speech
- Unsteady balance or coordination
- Confusion, slow responses, or difficulty following instructions
These observations can be important, but they are also subjective and can be challenged.
2. Driving Pattern (If Observed)
If the officer observed driving, the state may rely on:
- Lane violations
- Speeding or driving too slowly
- Wide turns
- Failure to stop properly
- Accidents or near misses
However, many DWI arrests happen without an officer actually witnessing “bad driving,” especially when the person is contacted after stopping or parking.
3. Field Sobriety Tests
Field sobriety tests are often a major part of no-test DWI cases. The most common standardized tests include:
- Horizontal gaze nystagmus (HGN)
- Walk-and-turn
- One-leg stand
Field sobriety tests can be influenced by many non-alcohol-related factors, such as:
- Medical conditions or injuries
- Age, weight, or balance issues
- Nerves, anxiety, or confusion
- Poor instructions or uneven testing surface
- Weather, lighting, or footwear
In no-test cases, careful analysis of how the tests were administered and recorded can matter a lot.
4. Statements Made by the Driver
Prosecutors may rely on statements such as:
- Admissions of drinking
- Statements about where the person was coming from
- Explanations that appear inconsistent
Sometimes a statement that sounds harmless (“I had a couple”) becomes a key point in a no-test case because it helps the state build a narrative.
5. Circumstantial Evidence
Other evidence may include:
- Open containers
- Witness statements
- Receipts, bar tabs, or social media evidence
- Video from bodycam, dashcam, or nearby surveillance
In some cases, the state will try to prove impairment mostly through circumstances rather than any scientific measurement.
What If You Refused a Breath or Blood Test?
Refusal cases are often treated differently than “no-test” cases where a test was never offered. In a refusal case, prosecutors may argue that the refusal itself suggests consciousness of guilt.
Refusal can also trigger separate administrative consequences for your driver’s license. If refusal is an issue in your case, the details and timeline matter.
What If There Was No Test Because of a Medical Issue or Other Problem?
Sometimes there is no chemical test because:
- the person was taken to a hospital and testing did not occur
- the officer did not complete the testing process
- equipment was unavailable or malfunctioned
- the arrest occurred under unusual circumstances
When there is no test for reasons unrelated to refusal, the defense analysis often focuses on whether the remaining evidence is strong enough to prove impairment beyond a reasonable doubt.
Are No-Test DWI Cases Easier to Defend?
Often, yes. Chemical tests provide the state with a number that feels objective to a jury. Without that number, the state’s case typically depends on subjective observations and interpretations.
But every case is different. Some no-test cases still have strong evidence, especially if there is video, a crash, clear impairment signs, or detailed corroboration.
Bottom Line
A chemical test is not always required for a DWI conviction in Arkansas. Prosecutors can attempt to prove impairment using officer observations, field sobriety tests, driving behavior, statements, and other circumstances.
However, when there is no breath or blood test, it often creates more room to challenge the proof and the assumptions being made about impairment.
If you were arrested for DWI and there was no chemical test (or you refused testing), it is often worth getting a clear assessment of what evidence the state actually has and how it may be challenged.
