I saw the sign

I was driving home from work today when I saw this sign on Highway 401. It's the first time I saw a sign say something like this. I don't know what the relavance of that sign is even now. The news didn't mention anything about a runaway vehicle.

 

I suspect it would have to be something pretty major as it warranted an amber alert and signs put up on the highway. I wonder what happened to that pickup.

 

I guess I may never know.
