Congress Overrides Lula Veto to Restore Toxicology Test for First-Time A and B Licenses

Overview

• The override makes a negative toxicology exam a prerequisite for obtaining the first CNH in categories A (motorcycles) and B (cars).
• The law sets a minimum 90-day retrospective detection window and a 90-day validity period for the test.
• Clinics that conduct physical and psychometric exams may serve as collection points when linked to Senatran-accredited laboratories.
• Lawmakers also reinstated electronic vehicle transfer and recognition of advanced or qualified digital signatures on platforms approved by Senatran or state Detrans.
• The presidency had rejected the requirement over cost and access concerns, while supporters pointed to recent CNH rule easing and noted that exam prices vary by region.
