I found an accident on Google Maps aerial imagery:

I figure there must be plenty of these between the aerial imagery and street view.
What one's have you found?
Imagery from other sources is ok too.
Also other incidents like spills could be fun to see too.
At the date of photography this wasn't an ongoing incident, but it shows the remains of one. By chance I drove by there either later the same day or the next day. There were work crews and people were stopping to take photographs. I saw, for the first time I remember, an orange "incident ahead" sign. I don't remember when that was. The imagery is from 3-30-12. The last time I went that way it was dark, so I didn't see it. I did see it still out there in October.
