春运自驾回家，要小心高速上这道“危险缝隙”！

Core Viewpoint - The article emphasizes the dangers of evacuating from elevated highways during accidents, highlighting that jumping over barriers can lead to severe injuries or fatalities, as illustrated by several case studies of accidents involving falls from high bridges [1][8]. Group 1: Accident Cases - On February 3, 2026, a truck driver in Fujian jumped from a high bridge while attempting to escape a perceived collision, resulting in him being trapped upside down in a gap, approximately 20 meters above ground, but was rescued by firefighters [1]. - On May 2, 2025, a drunken man fell from a 10-meter high bridge in Jiangxi and was subsequently rescued by firefighters after being immobilized [3]. - On January 22, 2024, a family of four fell from a 10-meter high bridge in Hunan due to a combination of icy weather and a traffic accident, but they were rescued and received medical attention [6][8]. Group 2: Structural Design and Safety Recommendations - Most highway bridges in China utilize conventional structures like hollow slabs and T-beams, with gaps between separated lanes typically ranging from 30 to 50 centimeters, which can sometimes exceed 1 meter [10][12]. - The design of these bridges aims to prevent vibrations from affecting the structural integrity, thereby extending the lifespan of the bridges [12]. - To avoid accidents, it is advised that drivers and passengers refrain from blindly crossing central barriers on bridges, especially during adverse weather or traffic conditions, and to remain patient during traffic jams [12].
