Drivers stopped for suspected drunk or drugged driving in St. Louis County are now subject to a “no-refusal” policy for DWI chemical testing. The county is just one of the jurisdictions in Missouri that have adopted the policy: if you decline a breath test, officers can quickly get a warrant for a blood draw. A skilled DWI defense attorney can help mitigate the damage and protect your rights.
What “No-Refusal” Means
Under Missouri’s implied consent law, every driver automatically agrees to submit to a chemical test of their blood, breath, or urine when lawfully arrested for driving while intoxicated (DWI). Refusing that test used to carry an automatic one-year license revocation. Many drivers still chose refusal because it limited the evidence prosecutors could use in court.
Now, in St. Louis County, refusing the test won’t necessarily keep that evidence out of the case. If you refuse to blow into the breathalyzer, the officer can request a warrant from a judge right away to have a medical professional draw your blood. Prosecutors and police have set up a system where an on-call assistant prosecutor will review search warrant requests during DWI stops. This policy applies to alcohol as well as suspected drug impairment, including prescription or controlled substances.
So, why is this important? Generally, law enforcement cannot take a blood sample without either your consent or a valid search warrant. The new “no-refusal” approach speeds up the warrant process. Judges are available around the clock to review electronic applications from officers, who must provide probable cause that the driver was impaired. Once signed, the warrant authorizes a blood draw—even if it’s against your wishes.
Potential Legal Issues and Challenges
While the county’s goal is to reduce impaired driving, the policy has problems. Defense attorneys have pointed out that not all hospitals or medical staff are willing to forcibly take a person’s blood, even with a warrant. Many facilities worry about liability if something goes wrong during a forced blood draw. If a nurse or technician refuses to cooperate, that could affect whether evidence is admissible in court.
There are also concerns about the blood sample quality and handling. Chain of custody, contamination, and timing can all influence test results. These are the kinds of details defense attorneys use to determine whether a client’s rights were violated or if the evidence is unreliable.
How This Could Affect DWI Cases
Before the “no-refusal” policy, refusing a breath test could limit the evidence prosecutors had available. Without a chemical test result, they often relied on officer testimony, dashcam footage, and field sobriety tests. Now, prosecutors may have stronger evidence to present—assuming the warrant and blood draw were handled correctly.
However, there are still opportunities for legal challenges. A defense attorney might question:
- Whether the officer had probable cause for the warrant.
- Whether the warrant was properly obtained and executed.
- Whether the blood draw complied with Missouri Department of Health regulations.
- Whether the sample was analyzed using approved methods and equipment.
If any of these steps were mishandled, the test results could be suppressed. This weakens the prosecution’s case and could lead to dismissed or reduced charges.
What You Should Know If You’re Stopped
If you’re pulled over for suspected DWI in St. Louis County, the officer will likely ask you to perform field sobriety tests and take a preliminary breath test. You still have the right to refuse both, but now that refusal may not prevent a blood draw.
Officers can detain you while they apply for a warrant. Once the judge approves it, a medical professional can draw your blood—even if you continue to refuse. Refusal still triggers an automatic license revocation under the implied consent law, so you could face both administrative and criminal consequences.
