(1) prohibiting the license holder from driving a vehicle equipped with air brakes; and
(2) as provided by 49 C.F.R. part 391, prohibiting driving a commercial vehicle in interstate commerce by a person who:
(A) is under 21 years of age;
(B) does not meet applicable physical guidelines; or
(C) cannot sufficiently read and speak the English language.
(b) For purposes of this section, the department may not administer examinations or tests relating to the applicant’s proficiency in the English language, but if an applicant cannot speak English sufficiently to communicate to department personnel the applicant’s need for a commercial driver’s license, the department may issue to the person a commercial driver’s license restricted to operation in intrastate commerce.

(c) A person commits an offense if the person drives a commercial motor vehicle in violation of a restriction. An offense under this section is a Class C misdemeanor.
