Why can a driver be arrested for DUI even with a BAC below 0.08%?
- A.Officers may arrest anyone at random
- B.The limit applies only on freeways
- C.Below-limit driving is always a DUI
- D.Because driving while actually impaired by alcohol or drugs is illegal regardless of the exact number
Correct answer
D. Because driving while actually impaired by alcohol or drugs is illegal regardless of the exact number
Why
The 0.08% figure is a per se limit, not a safe harbor. If alcohol or drugs impair your driving ability, you can be convicted of DUI below that BAC.
