Question: What is the maximum allowed blood alcohol concentration (BAC) for fully licensed G drivers aged 22 or older in Ontario?
Answer options:
- 0.02%
- 0.05% ✅ 0.08%
- 0.10%
Correct answer: 0.08%
Explanation: In Ontario, the maximum legal blood alcohol concentration for fully licensed drivers aged twenty-two or older is 0.08 percent, which is the statutory threshold for criminal impaired driving charges. While a concentration of 0.05 percent falls into the provincial "warn range" and triggers immediate roadside suspensions, it is not the maximum legal limit. The 0.02 percent option is incorrect, and 0.10 percent exceeds the legal limit. Under Ontario law, novice drivers and those under twenty-two must maintain a zero blood alcohol concentration. Distinguishing between the zero-tolerance rules for new drivers and the standard limits for experienced drivers is essential for passing the G1 exam.
