When is it legal to drive with an open container of alcohol?

Answer: C — Never; it is illegal

Driving with an open container of alcohol is illegal in Washington State at all times. This law is in place to promote safer driving conditions and reduce the likelihood of alcohol-related accidents. An open container includes any bottle, can, or other container which has been opened and contains alcohol. The prohibition extends not only to the driver but also applies to passengers in a vehicle. During special events or while parked may seem like exceptions, but the law is strict to discourage any consumption of alcohol that could lead to impaired driving or unsafe behavior in and around vehicles. The underlying goal is to ensure that drivers remain sober and focused while operating a vehicle, thus enhancing public safety.
