The type of crack formed on your windshield can actually tell you a lot about the impact, including what hit the glass and the impact velocity. Studies show that the number and the pattern of cracks radiating out of the point of impact on the glass can reveal the underlying material properties and the velocity of impact. Researchers have found, for example, that the number of cracks formed is equal to the square root of the impact velocity. These revelations may be very useful to forensic investigators. This might also help you identify what exactly broke your windshield in the parking. But thanks to windshield replacement shops in Oakville, you don’t have to fret over it.
