The car smashed into the box near Kinning Park Subway station in Glasgow at about 12.40am yesterday.
Commuters faced major disruption after the underground station closed to all passengers. About 40 homes and a nursery were also affected by the power fail.
The power was restored to the properties at around 12.30pm and the station reopened shortly after.
The car, believed to be a new Ford Fiesta, was wrecked when it crashed through the box and into railings overlooking the motorway. After the collision, which seriously damaged several power cables, the driver ran off. The car was removed from the scene and police launched an investigation.
ScottishPower engineers worked through the night to dig up the road and reconnect the electricity.
Residents described how they heard a loud bang before being plunged into darkness.
Gerry O'Hara said: "I was lying reading my book and I suddenly heard a loud noise and all the lights went out. I first thought it was a crash on the motorway, it sounded very serious.
"It's a major inconvenience not having power but the car could have gone right onto the motorway which would have been awful."
John Mawer, 40, who has lived in the area for 11 years, said: "It's a very quiet road - and it's a dead end - so it's unusual for a crash to happen."
