Indianapolis - Colton Harta was cleared to drive in the Indianapolis 500 on Saturday, a day after he overturned in a horrific accident.

Andretti Autosport driver walked out of the Infield Care Center unharmed but needed further assessment before getting the green light for Sunday's race.

Andretti Autosport posted on Twitter on Saturday that it had been "officially cleared by Indica Medical" to participate in the Harta 500.

With 25 minutes left on Carb Day, his car number 26 was destroyed in an accident on Friday, forcing his team to shake to prepare the backup. He will make his 25th debut at IndyCar's premier event

The 22-year-old Californian was talking on his team radio when his car was still spinning. When it stopped, his father, Brian, radioed Harta to be held until emergency workers released him.

His father went to Andretti's garage to oversee the preparation of his race strategist and immediate backup vehicle.

Harta got her first win of the Indica season earlier this month with an amusement drive through the rain on the road course at the Indianapolis Motor Speedway.

Last year, Harta qualified second for the Indie 500, started at the front row and lapped 13 before his strategy failed, and he faded to a disappointing 16th place finish.

"I think I was going a little too fast for that corner," Herta said. With 25 minutes left on Carb Day, the crash destroyed Andretti Honda and Hart will need a backup for Sunday's race. He also blew up an engine to qualify and Andretti would start on the 25th in any car that could be ready for race day.
