Which Blood Alcohol Concentration (BAC) level can lead to a driver's licence suspension under the Highway Traffic Act?

0.05
0.06
0.07
0.08

The correct answer is: 0.05

The correct answer is that a Blood Alcohol Concentration (BAC) level of 0.05 can lead to a driver's licence suspension under the Highway Traffic Act. At this level, drivers are considered to be at an increased risk for impaired driving, and various jurisdictions have implemented laws to enforce immediate consequences for operating a vehicle with this BAC. In many regions, drivers may face penalties such as a licence suspension, fines, and even mandatory education programs when their BAC reaches 0.05 or higher. This is part of a broader effort to enhance road safety and reduce incidents of impaired driving by discouraging consumption of alcohol before driving, even at relatively lower levels. Higher BAC levels, such as 0.06 or 0.07, also present risks and can trigger different regulations, but 0.05 has become a critical threshold for immediate suspension measures in various laws aimed at preventing alcohol-related accidents.
