1. For drivers 21 years of age and older, driving with a blood alcohol concentration (BAC) is considered illegal starting at:
0.05%
✓ 0.08%
0.10%
Any detectable amount
Why: 0.08% — the legal limit for drivers aged 21 and older.
2. What is the legal blood alcohol concentration (BAC) limit for drivers under 21 in Georgia?
0.08%
0.05%
✓ 0.02%
There is no limit for drivers under 21
Why: Georgia has a zero-tolerance law for drivers under 21: a BAC of just 0.02% or higher is enough for a DUI charge.
3. A commercial vehicle driver is considered to be intoxicated if their BAC is:
0.08%
✓ 0.04% and higher
0.02%
0.10%
Why: For commercial drivers, a stricter limit applies—0.04%.
4. What does Georgia's "implied consent" law mean for drivers?
Drivers may refuse a breath or blood test at any time with no consequences
✓ By driving on Georgia roads, a driver has already agreed to a chemical test if lawfully arrested for DUI
Only drivers with a commercial license are subject to chemical testing
Implied consent applies only to drivers under 21
Why: Under implied consent, simply driving in Georgia means you've agreed to submit to a chemical test (breath, blood, or urine) if you're lawfully arrested on suspicion of DUI; refusing can bring its own penalties.
5. Drivers and passengers are prohibited from having the following items inside the vehicle:
Food or drinks
✓ An open container of alcohol
Phone Holder
Sunglasses
Why: Open containers of alcohol are prohibited inside the vehicle for both the driver and passengers.
