The department must receive notification of no security threat from the appropriate federal agency conducting the background check within 90-days from the CDL issuance date to maintain this endorsement.(f) Persons who do not take and pass the air brake exam will be restricted to driving vehicles without air brakes. Applicants holding an out-of-state CDL will be exempt from this exam unless that license indicates they are restricted to driving vehicles not equipped with air brakes.(g) The department shall waive the CDL knowledge exams required by Texas Transportation Code, § 522.022 for applicants who meet the conditions and limitations provided by 49 CFR 383.77.
