Suggestions

Traffic lights are a suggestion - not necessarily the law or the way to regulate traffic here in Seattle. When the light is yellow it is suggested that you speed up and if it is red then go if the vehicle in front of you made it. Absolutely do not go if the light is green until you're sure all of the other vehicles burning the red have made it through. That is the suggested way of driving through this fine city. (Though, according to my father, this is pretty characteristic of the west.)

It is suggested that you stop for pedestrians even if they don't appear to be crossing the street.

Also, it is suggested to always bring an umbrella because even if it's been 40 degrees and sunny for the past three weeks it will eventually rain... you're in Seattle after all.
