On February 4, 2019, NASCAR announced a change in the qualifying schedule procedures for the majority of its tracks. For short tracks and intermediate speedways, the first round will be shortened from 15 minutes to 10 minutes, while the second and third rounds will remain at 10 and five minutes, respectively. The downtime intervals at all tracks will be reduced from seven minutes to five minutes. Superspeedway qualifications will retain their untimed two-round intervals of single-lap qualifying while road courses will continue to use two qualifying rounds: 25 minutes for the first round and 10 minutes for the final round.[85]
On May 1, 2019, following continued gamesmanship and other actions causing multi-car qualifying to become "untenable," NASCAR formally returned to single-car qualifying at all oval tracks. Knockout-Style qualifying would be kept at Watkins Glen, Mid-Ohio, Road America, and the Charlotte Motor Speedway Roval.[86]
At oval tracks 1.25 miles and larger, each car will get a single timed lap.
At oval tracks 1.25 miles and smaller, each car will get two timed laps with the faster lap counting as their official time.
The qualifying order draw will be determined in part by the previous race's starting lineup. The top 20 starters from the previous race will draw to take their qualifying lap in positions 21–40 (the second half of qualifying). The remainder of cars will draw to qualify in positions 1–20.
The next car will be sent once the preceding car takes the white flag. This should ensure qualifying is completed in roughly 40 minutes baring any interruptions for crashes, debris, or weather.
There will be two-minute TV breaks built into qualifying to ensure every car gets covered live during the session.
Broadcasters FOX and NBC have committed to using ghost car graphics and impose other technologies to make the session more exciting to TV viewers.
Each car must complete their lap for the session to be counted, otherwise all times will be erased and cars will start by owner points.
