A 31-year-old San Jose driver was speeding at over 140 mph on Highway 87 when he crashed into another vehicle in December 2025, killing a mother and her 2-year-old daughter. Zachary Chernicky has been arrested and charged with murder. This case reflects the ongoing danger of high-speed driving on highways — at those speeds, driver reaction time becomes nearly irrelevant and collision forces are almost always fatal for occupants in smaller or slower vehicles.
