On the side of a car there is only a door. A frontal crash spends a foot or two of folding steel before anything reaches the people inside. A side impact reaches the person on the struck side almost at once, through a door, a window and a pillar a few inches away.
The count. Sorted by where the vehicle was hit, side impacts accounted for 22 percent of the people killed inside passenger vehicles in 2024, second only to frontal crashes at 59 percent and far ahead of rear impacts at 5 percent. In cars the side share was 26 percent; in pickups, 16 (Insurance Institute for Highway Safety).
What the pattern says. In a frontal crash the hood and the engine bay fold, and the folding is time: the belt and the airbag use it to slow the body before it reaches anything hard. On the side there is almost none of that. The front of the striking vehicle, the door, and the near-side occupant’s chest, pelvis and head start out inches apart, so the structure taking the crash and the person it protects are in nearly the same place. That is why the injuries gather on the struck side, which is what Inches of Steel explains, and why the front of the other vehicle matters so much. When the Insurance Institute toughened its side test in 2021, it made the striking barrier heavier and faster to match today’s traffic: 4,200 pounds at 37 mph, close to the weight of a midsize SUV, instead of 3,300 pounds at 31 mph, 82 percent more energy (IIHS). Its striking face sits at about the height of a modern SUV’s bumper and grille (IIHS side test).
What the standard asks. The federal side-impact standard exists “to reduce the risk of serious and fatal injury to occupants of passenger cars, multipurpose passenger vehicles, trucks and buses in side impacts” (Federal Motor Vehicle Safety Standard 214). It runs two crashes. A moving barrier strikes the side at 33.5 mph. Then the vehicle itself is pushed sideways, at up to 20 mph, into a pole ten inches across, lined up with the head of the dummy in the front seat, and the measured head injury number has to stay within the limit. When a door, a pillar or the head protection did less than it should have, that is the question Crashworthiness takes up, and answering it requires keeping the car as it is.
Where the law comes in. Side impacts often happen where two paths cross, and Texas law starts with the driver who had to stop. Under Transportation Code Section 545.151, a driver required to stop and yield, at a stop sign, a yield sign, a signal gone dark, or certain uncontrolled intersections, who then collides with the traffic he had to yield to “is presumed not to have yielded the right-of-way,” and a crash after driving past a yield sign without stopping is prima facie evidence of a failure to yield (Section 545.153). A presumption is where the argument starts, not where it ends. The driver with the right of way still has to drive at an appropriate reduced speed approaching and crossing an intersection (Section 545.351), Failure to Yield explains how speed and sightlines move the question, and a Texas jury assigns each party its own percentage of responsibility, which is Comparative Fault.
No one is named here, and nothing on this page decides a particular crash. On the side of a car there is only a door, and after a side impact every inch of it is evidence.
