The Fourth of July weekend means a lot of family time, BBQs, fireworks and flags, and many miles of road trips. It also means more drunk drivers driving everywhere across the US. According to the National Highway Traffic Safety Administration (NHTSA), the 4th of July is one of the deadliest holidays of the year due to DUI accidents. In 2014, half of the fatalities included a person driving under the influence, and 41% had a blood alcohol concentration (BAC) over the drinking and driving legal limit of .08.
