Which of the following is a driving offense in Delaware when it comes to alcohol consumption?

Driving with a Blood Alcohol Concentration (BAC) above the legal limit is considered a serious driving offense in Delaware. The legal BAC limit for drivers over the age of 21 is 0.08%. Driving under the influence of alcohol significantly impairs a person's ability to operate a vehicle safely, leading to an increased risk of accidents, injury, and fatalities. This regulation is designed to promote safe driving practices and protect all road users.

While consuming alcohol in a parked car or having an open container can also have legal implications, particularly regarding public intoxication or other municipal codes, they do not directly affect the operation of the vehicle in the same way as driving with a high BAC does. Additionally, drinking alcohol while stopped at a red light, although not advisable, typically does not constitute a driving offense unless combined with other infractions or if it leads to impaired driving.
