What BAC level can result in roadside penalties?

In many jurisdictions, a blood alcohol concentration (BAC) level of 0.05 is considered a critical threshold for legal penalties related to driving. At this level, individuals may face roadside testing consequences, including fines, license suspensions, or other penalties, even if they are not legally intoxicated according to higher thresholds like 0.08.

The reasoning behind this is that a BAC of 0.05 typically demonstrates enough impairment to affect driving ability, increasing the risk of accidents. Law enforcement aims to deter unsafe driving behaviors at this level to promote road safety. It's also important to note that some regions may impose stricter laws, leading to penalties for lower BAC levels, but 0.05 is widely recognized as a significant limit where law enforcement can take action.

The other options reflect BAC levels that may still be below or at the threshold for legal intoxication in certain areas, but 0.05 specifically highlights the level where penalties become more commonly enforced.
