Two drivers were taken to the hospital after two separate overnight crashes.
The first happened around midnight near 120th and Q streets.
Police said the driver had serious injuries. Speed and icy road conditions are considered factors in the crash.
Around 1 a.m., an SUV rolled as the driver was exiting northbound JFK onto Lake Street, according to police.
That driver was also taken to the hospital with serious injuries.
Both crashes are still under investigation.
