Can you legally have an open container of alcohol in the car if someone else is holding it?

In Massachusetts, it is illegal to have an open container of alcohol in a vehicle, regardless of who is holding it. This law is designed to discourage drinking and driving and to enhance road safety. The law applies to both drivers and passengers; therefore, an open container in the vehicle, even if it is being held by someone other than the driver, constitutes a violation.

The general principle is that any open alcoholic beverage in a moving vehicle can present a risk, which is why strict regulations are in place to prevent access to open containers while traveling on public roads. This is an important aspect of safe driving practices and overall public safety, which reinforces the importance of responsible behaviors regarding alcohol consumption in vehicles.
