Police say a medical helicopter was hit by a car and disabled as it prepared to transport an injured pedestrian, and the car's driver now faces drunken driving charges.

The Florida Highway Patrol says the helicopter landed in the middle of U.S. Highway 192 near Walt Disney World early Wednesday morning to pick up the patient who'd been hit by a car.

An arrest report says 20-year-old Cameron Sunderly drove his car around emergency vehicles blocking the road and crashed into the helicopter's rear rotor.

Sunderly told troopers he'd been at an Applebee's restaurant. A breath test measured his blood alcohol level at more than twice the legal limit, five hours after the crash.

It's not clear whether Sunderly has a lawyer.

Detains on the pedestrian weren't immediately available.
