What is the legal BAC (Blood Alcohol Concentration) limit for drivers over 21 in Delaware?

In Delaware, the legal Blood Alcohol Concentration (BAC) limit for drivers who are over 21 years of age is set at 0.08%. This regulation aligns with the standards established by many states across the U.S. to help ensure road safety and reduce the likelihood of accidents associated with impaired driving.

When a driver's BAC reaches or exceeds this level, they are considered legally impaired, and law enforcement has the authority to enforce penalties such as fines, license suspension, and even jail time for DUI (Driving Under the Influence) offenses. This specific limit is based on extensive research indicating that a BAC of 0.08% significantly increases the risk of crash involvement and diminishes the driver's ability to operate a vehicle safely.

The other options provided do not reflect the legal standard in Delaware. For instance, while a BAC of 0.05% may not be grounds for a DUI in some jurisdictions, it is still higher than the zero-tolerance level for underage drivers. Meanwhile, 0.10% and 0.12% are above the legal limit, reinforcing that driving at these BAC levels in Delaware would lead to legal consequences.
