Why Timely Filing Matters?
Illinois regulations require commercial driver training schools to maintain accurate records of licensed instructors. Failure to notify the Secretary of State of an instructor’s termination can create compliance issues during audits, license renewals, or investigations. Under Section 6-420 of the Illinois Vehicle Code, the Secretary of State may take action against a school or instructor license for failure to keep required records or comply with rules.
Keeping instructor status current also helps the state maintain an accurate roster of active licensed instructors available to teach behind-the-wheel or classroom instruction.
