Thanks for all the comments. First off, the driver did STOP. The driver had no choice as a car past in front while at the STOP sign. If you look carefully in front of the car, you can see a set of lights (red on top – yellowish on bottom). The same set of lights are on the short side of the STOP sign. The vehicle in the photo isn’t going that way as the driver has turned on their left blinker. You can see the vehicle travels less distance for each blink. That about covers it.
I think the sign is too close to the edge of the frame, and I think you included too much ground, but tahts probably just me. I also think you should use a more neutral border colour.
Although it's well shot and interestingly-lit, I don't think you need nearly so much foreground. Since the subjects are so near the top, I'd try a severe crop (1/3 to 1/2 off the bottom) and make it a more panoramic shot. That should also accentuate the look of speed.
Great exposure. I'm not fond of the title, but it doesn't matter. The pic is cool. I like the long exposure pics in general and this one is exceptional. I might've cropped out some of the snow though. Great pic - Inspzil
Nice shot but in my opinion there's too much earth in the foreground, it would have been better either to crop it completely or have the sky as the extra space.
Did he stop? Yes, judging by the image of the car stationary. In general the lighting is very good - it's a shame that there is a reflection on the stop sign itself. The brown border is interesting - probably not my first choice but it does kind of suit the snow (which looks brown at the bottom of the photo).
