State of WA/ID
Is there an allowance of a number of feet they give you to slow down after a speed limit sign is posted, or are you supposed to be at that speed by the time you reach the sign?
Say you're doing 60 in a posted 60mph zone out on the highway and round a corner to immediately notice a 25mph sign you just passed with an officer sitting on the other side of it with his radar on, ready to write you a ticket for 60 in a 25.
