Aggressive driving can lower gas mileage by 33% on the highway and 5% in the city, but that wasn’t the motive for this NYPD traffic agent whose aggressive and destructive driving led to the death of a 21-year-old woman.

NYPD traffic agent Stefan Hoyte, 26, was arrested on charges including DWI and vehicular homicide after his car slammed into a barrier on the Williamsburg Bridge around 3:15 a.m. March 16.

Police say victim Amanda Miner was out celebrating her 21st birthday with Hoyte and another off-duty NYPD traffic agent who was Miner’s boyfriend.

Sources say Hoyte was allegedly intoxicated and speeding when he lost control of the vehicle and split the vehicle in two after crashing into the divider. Miner was pronounced dead at the scene after being ejected from the car.

The victim’s mother, Virginia Cabrera Miner, expressed immense grief at the situation.

“All I know is that my baby’s gone, that’s a tragedy…yesterday was her 21st birthday and now I’m not gonna be able to see her graduate from college.”

Miner’s family said she had been attending Lafayette College in Pennsylvania, studying social work.

“Ever since she was little, she was all about helping people standing up for the little guy’s rights, for everyone,” said her mother. “She could have changed this world. She changed mine. But now, we’ll never get to see how far she could have gone.”

As a millennial, Miner had great potential. Millennials officially make up the largest share of the workforce, and 91% of them stay at a job for less than three years. However, this isn’t because they’re lazy or don’t want to work — it’s because they’re ambitious.

Hoyte and the other off-duty traffic agent involved in the crash were taken to Bellevue Hospital and treated for minor injuries.

As a result of his carelessness, it’s expected that Hoyte will be charged with criminally negligent homicide and moving violations. With the summer months quickly approaching, these types of accidents are only likely to increase. According to the National Highway Traffic Safety Administration (NHTSA) a higher volume of travelers combined with more alcohol-impaired drivers cause nearly two times the number of auto accident fatalities during summer months than during the rest of the year combined.

Residents in the area note that people often go too fast when traversing the Williamsburg Bridge.

“People driving too fast on the Williamsburg,” said Jimmy Salazar. “I don’t know why, especially in this weather. You not supposed to do that.”
