Bumpers are a first line of defense in crash safety, but when it comes to accidents involving cars and SUVs, they often do more harm than good.
The problem stems from the imposing height of SUVs, which puts their bumpers several inches higher than those of smaller sedans on the road. So, when SUVs collide with cars, there is no bumper bumping. Instead, the SUV bumpers slam into the body of the autos themselves, smashing the lights or even cracking the radiator — and possibly causing severe injuries.
That also means mighty expensive repairs, even in relatively mild collisions. According to accident tests conducted by the Insurance Institute for Highway Safety, a 10 mph rear-end crash involving a Ford Focus (a compact sedan) and a Ford Escape (a smaller SUV) results in more than $5,203 of damage for the Focus, and $2,208 for the Escape.
A comparable crash between a Nissan Rogue (SUV) and a Nissan Sentra (car) resulted in $7,444 in damage overall for the two vehicles. Other crash tests revealed similar results for a wide range of brands.
The height discrepancy is due to the absence of bumper standards governing SUVs and other light trucks. While federal regulations mandate that smaller cars have a bumper at 16 to 20 inches from the ground, no such rule exists for SUVs.
“SUVs and cars share the road,” says Joe Nolan, the chief administrative officer of the insurance institute. “The problem is they don’t share the same bumper rules, and consumers end up paying the price.”
The issue isn’t just one of repair costs. Safety advocates have long argued that the mismatch in height and size of vehicles increases the severity of injuries because the bumpers of taller trucks and SUVs strike above the best protected parts of smaller vehicles.
The insurance institute petitioned the National Highway Traffic Safety Administration in July, 2009, to impose a single standard for bumpers, which has been rejected by car companies. NHTSA has not yet issued a ruling on the petition but, The New York Times reports, the agency previously has held off on issuing a standard for SUVs and other light trucks, on the theory that it might make it difficult to operate as intended, including off-road driving.
