What Makes a High-Speed Highway Crash So Damaging
Route 101 carries highway speeds through Auburn, and speed is the biggest factor in how much force a crash produces. When two vehicles close on each other at 65 mph combined speeds, or when a moving vehicle strikes a slowed or stopped one, the energy that has to be absorbed rises fast, not in a straight line, as speed increases.
Modern vehicles are built with crumple zones at the front and rear designed to collapse and soak up that energy before it reaches the passenger cabin, which is built stiffer to hold its shape. Seat belts and airbags work together: the belt keeps an occupant positioned so the airbag can do its job, and neither performs as intended without the other. A body moving at highway speed that is not restrained by a belt keeps moving even after the vehicle stops, which is why unbelted occupants are more likely to be thrown into the dashboard, windshield, or out of the vehicle entirely.
According to the National Highway Traffic Safety Administration, passenger vehicles made up 92 percent of registered vehicles and 89 percent of vehicle miles traveled in 2023. That volume means most highway crashes, including those on roads like Route 101, involve the ordinary passenger cars and SUVs that make up the bulk of traffic, where seat belt use and airbag deployment often determine how a crash turns out more than the vehicle's size or make.

What to Do After a Car Accident in Auburn, NH
If you're involved in a crash in Auburn, stay as calm as possible and check yourself and any passengers for injuries before doing anything else. Call 911 even if injuries seem minor, since some symptoms, especially from head or neck injuries, take hours or days to show up.
Once you're safe, get checked out by a medical provider, even if you feel fine at the scene. Keep records of any treatment, and follow up with your regular doctor if new symptoms appear later. Reporting the crash to your insurer and keeping a copy of the police report will also help if questions come up down the road.
