The timing of Sunday's wreck is notable.

According to TxDOT CRIS public crash records covering January 2020 to present, the corridor has seen 1,477 crashes within about a quarter-mile, including six fatal incidents. The most common contributing factor recorded by investigating officers is "Failed To Control Speed," cited in 603 crashes. The hit-and-run rate at this location stands at 10.1 percent—meaning roughly one in ten crashes involve a driver who leaves the scene.
