Questão jurídica principal
Whether holding and using a radio handset while driving constituted simple violation of traffic rules.
Decisão extraída
Yes. The prolonged use of the handset, with the driver’s hand occupied and posture changed, unlawfully hindered vehicle control and impaired attention.
Fundamentação extraída
Under the Traffic Act and ordinance, any maneuver that actually impairs attention or makes vehicle operation more difficult is prohibited; the facts found showed both effects here.
