Crashes involving sport utility vehicles, such as the recent incident on SR-57 near Pathfinder Rd, can pose significant risks due to the size, weight, and higher center of gravity of these vehicles. This stretch of SR-57 in Diamond Bar is a heavily traveled commuter route connecting Los Angeles and San Bernardino counties, with high traffic volumes during the evening hours. Sudden lane changes, distracted driving, or excessive speeds in these areas can quickly lead to serious accidents.
