Before you try to save a bunch of money on a new or used car, make sure you and your family will feel safe enough to trust your life with it when you travel. Check your car’s crash test ratings on Insurance Institute for Highway Safety (IIHS) before you seal your deal. Make sure your mind fully processes the images of frontal impact and side impact crashes on the website. Weigh your cost benefits against the risk factors before you jump to a decision.
I have deliberately avoided the use of the words “cheap car”. Once you go through the ratings, you will realize that expensive is not necessarily safe and cheap is not necessarily unsafe. You don’t need to spend a ton of money for a safe vehicle; just be well informed and make a reasonable safety conscious decision. ["reasonable" is the key word here; we might as well travel in an armored tank otherwise]
Once you are on the IIHS website, make sure you check out all three crash ratings:
1. Frontal Impact Offset Crash Test
2. Side Impact Crash Test
3. Rear Crash Protection/Head Restraint Ratings
For rollover safety ratings (and more crash ratings), visit NHTSA
Some of the summary features of the IIHS tests are listed below so that you can understand the results better:
- Frontal impact crash tests are conducted at 40 mph and the results are relative to the vehicles size/weights. You cannot compare these crash test results for a small car with a bigger car. You can compare vehicles of about the same weight (for example, compare a midsize sedan with another midsize sedan, a small car with another small car). Common sense suggests that with all other factors considered equal, bigger cars will be safer than smaller cars.
- Side impact crash test are conducted at 31 mph with a standard 3,300 pound moving barrier while the car is stationary. The results of this test can be compared across car sizes/weights. I was surprised to find that some small cars do better than some of the larger models in this test.
- Rear impact crash tests are conducted with a moving barrier that simulates a 20 mph impact by a vehicle of similar weight. Obviously, you cannot compare rear impact crash tests across different car sizes.
- A poor rating generally means a pretty good risk of a serious bodily injury irrespective of the size/weight of the car.
- Cars without side impact airbags have exceptionally poor side crash test results. In my opinion, these are must-haves.
- For those of us who indulge in cell phones and other trivia during highway driving, keep in mind that you car is tested for frontal impact at a measly speed of 40 mph ! A car with a very high frontal crash rating is no match for a 70 mph frontal impact. Infact, if you hit another oncoming vehicle travelling at 70 mph head-on, you are effectively crashing into a wall into a stationary vehicle at 140 mph !! Even divine intervention has little scope here. For some quick calculations on this click here.
So when you see that next car on sale, pull out your safety ratings information before you pull out your checkbook. Try to get a bargain value, but don’t compromise the safety aspects. Don’t get stuck with the cheap (or expensive), but totally not safe kinds.
