Stroller Collides with Truck---Strange Words

An article about the accident that killed a little boy in a stroller used these words to describe what happened:

"jogging stroller his mother was pushing collided with a semitrailer"


This phrase conjures up in my mind a vision of a really really big hefty dangerous stroller careening recklessly down the road, until it finally collides with a truck.

What really happened is not yet completely clear. The stroller, being pushed by a woman, whose son was inside the stroller, was hit while on the sidewalk by a rear tire of a semi making a turn.
