What is the legal blood alcohol concentration (BAC) limit for riders over 21 in Massachusetts?

In Massachusetts, the legal blood alcohol concentration (BAC) limit for riders over the age of 21 is 0.08%. This means that if a rider’s BAC is at or above this level, they are considered legally impaired and can be charged with operating under the influence (OUI). This standard aligns with laws across many states in the U.S., emphasizing the importance of keeping roads safe by discouraging impaired driving.

Understanding this BAC limit is critical for all motorcycle riders, as alcohol can significantly affect coordination, reaction times, and judgment—all of which are essential for safe riding. Therefore, it is essential for riders to be aware of this legal limit to avoid legal repercussions and ensure their safety as well as the safety of others on the road.

The other options present higher or lower BAC thresholds that do not reflect the legal standard in Massachusetts, thereby highlighting the specific nature of the legal limit set at 0.08%.
