A tractor-trailer was parked in the parking lot of the rest area when it was struck by a car.

The Florida Highway Patrol is investigating three fatal crashes on Central Florida roads.

It's not known why the tractor-trailer was hit by the car.

There were two deaths at the crash scene.

The man in the tractor-trailer was not hurt.

The motorcycle was removed from the crash scene.

The National Highway Traffic Safety Administration began an inquiry in August into a string of crashes in which cars using autopilot or traffic-awareness cruise control systems hit vehicles at scenes where first responders used flashing lights.

The cars with autopilot are a step closer to being recalled.

Emergency vehicles or trucks with warning signs are not included in crashes that are similar.
