Questão jurídica principal
How to classify the driver's conduct under the graduated license-withdrawal regime for defective tires on a wet road.
Decisão extraída
The conduct was not a serious violation, but it was a medium violation because the driver should have noticed and corrected the tire wear; a mere warning was not sufficient.
Fundamentação extraída
Wet-road driving with clearly insufficient tire tread created a traffic hazard, but no serious danger such as aquaplaning conditions was established. The driver's fault exceeded slight negligence because he used the car repeatedly over about ten weeks without adequate tire checks or replacement.
