PPG Presents Armed Forces Qualifying for the 110th Indianapolis 500 presented by Gainbridge is underway this afternoon at Indianapolis Motor Speedway, with more pressure than ever.

Due to qualifying getting rained out Saturday, all 33 drivers will receive just one four-lap qualifying attempt in the first round of time trials, which started at noon ET. That session will set positions 13 through 33 on the starting grid.

The 12 fastest drivers from the first round will advance to Top 12 qualifying, which starts at approximately 4 p.m. ET on the 2.5-mile oval. The six fastest drivers from that session will advance to the Firestone Fast Six at 6 p.m. ET, which will determine the first two rows of the starting grid and the NTT P1 Award winner for the coveted pole and the accompanying $100,000 bonus.

FS2 is televising the first round of qualifying. Coverage will shift to FOX at 4 p.m. for the Top 12 and Firestone Fast Six rounds. FOX One and INDYCAR Radio powered by OnlyBulls also will provide live coverage of all qualifying sessions.
