A dollar van driver killed a pedestrian and critically injured his wife in a Brooklyn hit-and-run Friday night.

The couple, a 47-year-old man and his 50-year-old wife, were crossing Flatbush Avenue near Avenue U in Marine Park at around 7 p.m. when the grey van plowed into them, police said.

After the impact, the driver continued down Flatbush Avenue before turning right onto Avenue V, cops said.

The husband died from his injuries at Kings County Hospital. His identity wasn’t immediately released.

The woman remains in critical condition with severe head trauma and internal injuries.

Police believe the dollar van is a Ford Omnibus. A grainy image was obtained of the vehicle from near the scene, police said.
