No one was hurt, but the crash shut down Elm Street for a while, police said.
Photographs supplied by Greenwich Police show a Chevrolet partially on top of another parked vehicle.
The driver can be seen in the vehicle, which is at a 45-degree angle and looks like it could fall on its side at any moment.
Greenwich police said only property damage was reported, no injuries.
The accident shows that hands-free devices aren't necessarily the answer to safe driving while using your phone, police said.
The driver in the crash was cited for distracted driving and failing to maintain lane despite his "adamant belief that he was not distracted while using a Bluetooth device," police said in a Facebook post.
"The driver could offer no explanation as how he ended up on top of a parked car when by witness and his own account there were no hazards present," police said.
Police said there were a couple of factors to consider: The road had minimal traffic at the time of the accident, the driver is a highly experienced limo driver who was sober, and the accident occurred during daylight hours with favorable weather conditions.
"Fortunately, no one got hurt so [the driver] only has to explain to a judge and his employer why he wasn't distracted and not to a grieving family," police said.
"Bottom Line: In order to stay safe, you need your eyes on the road, your hands on the wheel, and your mind on driving," police said.
