According to Texas law, an individual violates the open container law if they knowingly possess an open container in any area of the car located on a public roadway. Open container laws also apply to those parked in their car. Each incidence of open container possession counts as one offense, no matter how many open bottles are in the car.
Additional factors come into play when an officer charges you with possessing an open container. First offenses often come with the least severe consequences, but this changes when additional misdemeanors contribute to the original charge. Second and third offenses will also change how an officer charges you.
