Sample question from test 7
dui
Under Colorado's DUI per se rule, which blood alcohol concentration can support a conviction?
- More than 0.08%
- Exactly 0.02% for every driver
- More than 0.04% only for a commercial driver
- Any measurable amount, regardless of driver or conduct
Answer: More than 0.08%. The handbook says a driver may be convicted of DUI per se when the driver's BAC is greater than 0.08%. That threshold is different from the separate figures mentioned for drivers under 21 and CDL drivers, and it is not the same as saying every measurable amount automatically creates a DUI per se conviction. Impaired driving can also be established through behavior and the total circumstances. When reading a BAC question, identify the driver category and whether the question asks about per se evidence or broader impairment.
