Some places, but not like I would imagine one sees in LA or something. It definitely isn't the "everyone stop and sit" conditions I used to see in Munich.

Anchorage's traffic problems tend to revolve around narrow icy roads, which only get worse once it snows (they just keep piling the snow to the side of the road, usually without hauling it off until spring), high volumes of cars (more accurately a few cars mixed with a lot of big SUVs and trucks) racing stoplight to stoplight, poor planning, and poor maintenance.

Our drivers are pretty bad, I think partially due to prevailing attitude (we are an oil extraction "frontier" state), and partly due to the zombie-like state most people take on when the light goes away. Snow days are exciting as we right on the edge of a temperate rainforest, and can really get hammered by snow. I've seen cars stuck in the middle of the street -- they just couldn't go any further. On those days, I will sometimes ski in. It is a lot faster.

Please keep in mind this is mostly from a cyclist's perspective. I rarely start the truck, other than to get dog food, or to go play in the mountains/on the ocean.
