DUI and Drugged Driving
Know the numbers: BAC 0.08% is a DUI at 21 and over, 0.02% under 21; active THC 5 ng/mL at 21 and over, any detectable amount under 21. Refusing a test costs your license for 90 to 730 days. Sitting in the driver's seat able to control the car is "physical control," so you can be charged even while parked.
Prescription and over-the-counter drugs can be a DUI too, and mixing substances is the most common impairment in fatal crashes. Open alcohol and cannabis go only in the trunk or truck bed. A DUI stays on your record for life.
Example: after two drinks at a party you feel "fine" and climb into the driver's seat to sleep for a bit. Keys in hand, in the driver's seat: that already meets the definition of physical control.
