ORANGE COUNTY, Fla. – A suspected drunken driver rolled through a road block and crashed into into a medical helicopter that landed on an Orange County roadway to help a pedestrian who was struck by another vehicle, the Florida Highway Patrol said.

The chopper was called early Wednesday to U.S. 192 near State Road 429 near Walt Disney World after a man was struck by a car, the FHP said.

Deputies said the helicopter landed on the roadway, and the driver, identified by troopers as Cameron Brian Sunderly, 20, of Clermont, went through a roadblock and hit the tail of the chopper.

The helicopter was damaged and had to be towed from the scene.

The pedestrian injured in the initial crash was taken by ambulance to a hospital as a trauma alert. His condition is not known.

No other injuries were reported.

The FHP said Sunderly had a blood-alochol level of .187. The legal limit for driving in Florida is .08.

Sunderly was arrested on a charge of DUI with property damage and was taken to the Orange County Jail.

The crashes shut down U.S. 192 overnight, but all lanes later reopened.
