What is Brake Safety Day?

Brake Safety Day is one-day yearly inspection blitz conducted by the CVSA. During that day, CVSA-certified inspectors conduct routine roadside inspections with an extra focus on brake systems and parts. The brake violation data collected from the blitz is then sent back to CVSA to glean more about regulatory compliance and enforcement standards and general safety on the roads.
