Have you ever been in a motor vehicle collision which is also called a motor vehicle collision? This is when one vehicle crashes with another vehicle.
Why yes, I'm familiar with that concept. Fortunately, the worst I've been in could be classified "fender benders" -- nothing too serious, and usually the result of a lack of attention.
I was in one collision but luckily nobody was injured. Many collisions result in injury, death or damage to property. 
I'm glad you were okay. Did you both have insurance?
We did both have insurance. Globally, collisions lead to death and financial costs to both the individuals and society. Luckily we were covered.
