Yes, but in the US at least (I don't know about anywhere else, sorry), it's way too easy. If I remember correctly, the test was made for cars back in the 60s and basically every single car gets a 4 or 5 out of 5. If you've got two 4/5 cars, then one of them will surely be safer than the other, but unless the car is able to get a 5/5, there's no difference in the score.
