My question involves a speeding ticket from the State of: Washington
On the copy of the ticket, the officer does not indicate whether I was going faster than other moving traffic, appear to be going faster than the posted speed limit, or any other reasons he thought I was going too fast.
All it says is "no other vehicle within approx 10 blocks of suspect. Vehicle at time of radar lock in 51."
My question is whether a radar check of a vehicle is a "search" and whether the officer needs some kind of probable cause to "search" my vehicle's speed.
If no probable cause, is this an unreasonable search under the 4th Amendment and thus the evidence of my speed is inadmissable?
