With no explanation, chose the best option from "A", "B", "C" or "D". Dist. Court, 713 P.2d at 921. The plain language of this statute provides that if a person requests a blood test, "then the test shall be of his or her blood"; but if the driver requests that his blood not be drawn, then "a specimen of such person's breath shall be obtained and tested." § 42-4-1801(7)(a)[II)(A) (emphasis added). There is a presumption that the word "shall" when used in a statute is mandatory. See Dist. Court, 713 P.2d at 921. That presumption applies even in the negative-to wit: the driver "shall not be permitted to change such ° election." § 42-4-1301(7)(a)(II)(B) (emphasis added); see also Dike v. People, 30 P.3d 197 (Colo.2001) (finding the express consent law does not allow a driver to change his election of a test); People v. Shinaut, 940 P.2d 380 (Colo.1997) (<HOLDING>); Lahey v. Dep't of Revenue, 881 P.2d 458
