INDIANAPOLIS – NTT IndyCar Series officials have canceled the remainder of Thursday’s Indianapolis 500 open test at Indianapolis Motor Speedway due to weather.

However, officials are hoping to get the rookie and refresher courses in by 6:30 p.m. ET Thursday evening. If they are unable to do that, the rookie and refresher courses will take place Friday morning prior to the planned open test featuring more than 30 drivers.

After nearly getting the track dry enough to return to testing, rain that started at 3:14 p.m. ET ended up leading to the cancellation of the rest of Thursday’s open test. Testing was halted after less than two hours due to rain earlier in the day.

Conor Daly remains the fastest driver of the day with a fast lap at 222.714 mph in the No. 47 Carlin Chevrolet. He is followed by Ed Carpenter at 221.296 mph in the No. 20 Ed Carpenter Racing Chevrolet.

Six-time NTT IndyCar Series champion Scott Dixon is third in the No. 9 PNC Bank Honda at 220.575 mph followed by a pair of Arrow McLaren SP drivers, Felix Rosenqvist and Pato O’Ward, after both drivers turned laps at 220.360 mph and 220.233 mph, respectively.

Open testing is set to resume Friday with an improved weather forecast.
