I don't think any of the errors are material. The infraction quoted is RCW 46.61.400, which is correct. The officer's "description"of the violation won't matter or hurt you because the citation itself states your speed as measured (69mph) and the speed limit (55mph). Even if that speed limit is inaccurate, I wouldn't bring it up because speeding 69 in a 55 is better than speeding 69 in a 50.
