will
Mitchell v Wisconsin 2019
You arrest a suspect for DUI. They admitted they are high and drunk, and you see indicators of both intoxicants. You also found beer and marijuana in the center console. Do you do a breath or blood test?
Blood (if you think a combination)
47 OS 67-751
Policy 504.5.5
What BAC is aggravated DUI?
Is that a felony?
0.15 or higher
Not necessarily. Usually a misdemeanor for a first offense but it really just depends on how he is convicted/sentenced
47 OS 11-902.D
A man gets convicted of a DUI. In the following ten years, if he gets a second DUI, would it be a felony?
Yes, any DUI(s) within ten years of the first one would be felonies
47 OS 11-902.C.2
DUI arrests - Blood, Breath, and Refusals
In which instance do you seize the offender’s driver’s license?
In which instance do you provide the arrestee a copy of the IDAP form?
- You don’t ever seize their DL anymore (as of November 2021)
- You don’t do IDAP paperwork anymore (DUI violators arrested after November 2022 will be automatically enrolled in IDAP)
According to STATE LAW 47 OS 10-104.B, a driver who causes an accident resulting in death or GBI SHALL submit to drug and alcohol testing if there is probable cause to believe the driver ____
a, committed a citable traffic offense
b. did not have a driver’s license at the time of the accident
c. had improper equipment on their vehicle that mechanically failed
a. citable traffic offense (47 OS 10-104.B)
Note: If there is also PC they were DUI, they still have to be read implied consent, asked for consent for the blood draw, and if they refuse the blood draw, the Officer must get a warrant (State (OK) v Burtum 2023)
You have PC that an intoxicated driver committed a citable traffic offense then caused a SBI/death accident. You read them implied consent and they refuse the blood draw.
Do you need to get a warrant, or can you take their blood anyway pursuant to 47 OS 10-104.B (because they committed the citable traffic offense)?
Need warrant
State v Bartum 2023
- You respond to the call of vehicle with a flat tire. The driver is standing outside the vehicle when you arrive. No one saw him driving, and the vehicle is now inoperable/immobile. Can you arrest for DUI/APC?
- What if you notice a tire mark on the curb where the vehicle hit, which caused the flat tire. Could you arrest for DUI then?
- No
- Yes, because you have PC they were driving while intoxicated AND their vehicle was involved in an ACCIDENT

Yes
Pass/fail only, to show alcohol presence (can’t be used to show specific alcohol concentration)
State v Humberto (2020 OK CR 15) [cited in D21 PDR]
Does the body’s natural dissipation of alcohol create a per se exigency?
No
Missouri v McNelly 569 US 141 (2013); from D21 PDR
47 OS 10-104(B) has a per se rule permitting nonconsenual blood draws in cases where the driver was involved in a GBi/death accident and committed a citable traffic offense.
Does this law create a per se exigency justifying a warrantless blood draw?
No
Stewart v State, 2019 OK CR 6; from D21 PDR
(The above case found 10-104(B) unconstitutional, as it seems to automatically permit warrantless blood draws based on the flawed logic that a GBI/death accident created a per se exigency)
Are you REQUIRED to get a blood draw within two hours of an arrest?
No
Sanders v State, 2002 OK CR 42; from D21 PDR
Note: the blood draw should be done ‘as soon as practicable’ per State v Cudjoe S-2015-25, OCCA (unpublished, 8/5/2016)
