VIDEO: The moment a cement truck slams head-on into a car

This is what a university professor saw coming towards him as he waited at traffic lights in the US a couple of days ago.

Dr Guan Zhu , a veterinary professor at Texas A&M, is very lucky to be alive after this cement truck tipped on its side and slammed into his car in College Station on Wednesday.

As you can see, the front of his car was severely damaged, but fortunately for the doctor the rest of the car is untouched.

Afterwards, the professor said: "I could not remember exactly how it happened until the video showed me."
