Ever imagine what is the real meaning or specifications behind any vehicles sold in the market labeled with 5 stars safety rating?
This is the American rating for car crash safety rating:
Front crash:-
5 stars - 10 percent or less chance of serious injury
4 stars - 11 percent to 20 percent chance of serious injury
3 stars - 21 percent to 35 percent chance of serious injury
2 stars - 36 percent to 45 percent chance of serious injury
1 star - 46 percent or greater chance of serious injury
Side Impact:-
5 stars - 5 percent or less chance of serious injury
4 stars - 6 percent to 10 percent chance of serious injury
3 stars - 11 percent to 20 percent chance of serious injury
2 stars - 21 percent to 25 percent chance of serious injury
1 star - 26 percent or greater chance of serious injury
And after finding out their testing criterias, which is based on the following specifications, you might want to rethink the rating system, if it is truly reliable in saving one's life during accidents?
1. The tests are conducted at speeds of 35 to 38.5 mph. Wait a minute.....35-38.5 mph? Who drives 35-38.5 mph. when the rest of the world is traveling at 45-75 mph? The government safety ratings do not cover anything over 38.5 mph. The Insurance Institute for Highway Safety raises the bar though...they test at 40mph; a full 1 1?2 mile per hour faster...zoom, zoom.
2. Crash dummies only simulate full size adults, not teens, not children, not infants. Aren’t teenagers, children and infants passengers too? Why don’t they include it in the ‘rating’ system? The crash dummies are wearing seat belts in all cases, front and rear seats...(everyone in vehicles always wears their seat belts, don’t they?).
3. The crash dummies are wired to measure injuries to head, neck, chest, pelvis, legs and feet, but all these findings are not included in the rating. The ratings only measure head and chest injuries for frontal crashes and head injuries only for side crashes (evidently, other injuries are not serious enough to count in a government study).
4. Impact assumptions are for similar vehicles, differing no more than 250 lbs. This means if you are driving a small, full size or luxury car and you hit an SUV or a minivan...the rating doesn’t count (and it certainly doesn’t count if you happen to hit a tractor trailer...those crashes might change the star ratings).
5. Finally, the rating is only referring to injuries that require immediate hospitalization or are life-threatening.
If the above criterias applys, you would hence refer as:
1) If you happen to be in a crash faster than 38.5 mph, forget about the rating scales altogether!
2) If you are a teen, child or infant sitting anywhere in the car, forget about the rating scale altogether!
3) If you hit any vehicle that is larger, smaller, or not almost exactly what you are driving, forget about the rating scale altogether!
4) If you are not wearing your seat belt, forget about the rating scale altogether!
5) If someone at the accident scene says “you look fine”, forget about the rating scale altogether!
6) If you happen to be driving a “5 Star Rated” vehicle at 32 mph, hit a car head-on exactly like yours and are wearing your seat belt, according to the ratings you still have a 1 in 10 chance of being killed!
7) Lastly, if you are driving a “1 Star Rated” vehicle (I don’t know of any) and are in the same accident, you still have a 50-50 chance of surviving.
So, what is the conclusion?
1. Find out the car makers crash test specifications and criterias/assumptions.
2. Don't drive too fast?
3. Keep your distance front and rear
4. Wear your seatbelt, and make sure other passengers does too
5. Keep your car in top maintenance condition
6. Don't drink and drive!
7. Remember this topic whenever you speeding...lolx :_:
