The following procedures are required in K.S.A. 1998 Supp. 8-1002(c): "When the officer directing administration of the testing determines that a person has refused a test and the criteria of subsection (a)(1) have been met or determines that a person has failed a test and the criteria of subsection (a)(2) have been met, the officer shall serve upon the person notice of suspension of driving privileges pursuant to K.S.A. 8-1014, and amendments thereto. If the determination is made while the person is still in custody, service shall be made in person by the officer on behalf of the division of vehicles. In cases where a test failure is established by a subsequent analysis of a breath, blood or urine sample, the officer shall serve notice of such suspension in person or by another designated officer or by mailing the notice to the person at the address provided at the time of the test." In State v. Proffitt, 261 Kan. 526, 532, 930 P.2d 1059 (1997), the Supreme Court stated: "When a statute is plain and unambiguous, the appellate courts will not speculate as to the legislative intent behind it and will not read such a statute so as to add something not readily found in the statute."
