HILLSBOROUGH COUNTY, Fla. — A man was seriously injured after he had a medical emergency while driving on the Selmon Expressway Monday afternoon.
The Florida Highway Patrol said the 54-year-old man was driving a Ford F150 west on the expressway around 5:33 p.m.
He then suffered a medical emergency near 21st Street, which caused him to involuntarily accelerate forward and crash into a Toyota Tacoma and Nissan Armada traveling ahead of him.

The Ford then traveled to the median before colliding with a guardrail and structural support for the expressway's upper deck.
Upon impact, a tire from the Ford separated from the truck and traveled into the eastbound lanes, hitting a Volkswagen Jetta.
The Ford's driver was taken to a local hospital after he was seriously injured in the crash. All other drivers and passengers of the other vehicles were uninjured.
'Cruise lights' on Hillsborough County Sheriff's Office patrol cars raise questions, confusion among drivers
Every driver knows that when you see red and blue flashing lights on a patrol car, you slow down, pull over, or get out of the way.
But in Hillsborough County, drivers will also now see deputies with their lights on, but not flashing. They're called "cruise lights," and the Hillsborough County Sheriff's Office (HCSO) recently implemented their use on all patrol vehicles.
