Questione giuridica chiave
Whether the lower courts correctly applied priority rules and the duty of caution when visibility was partially restricted at the intersection.
Decisione estratta
The factual findings were insufficient to determine whether the appellant violated the priority rules; the conviction could not stand.
Motivazione estratta
The 'probing forward' rule applies only when visibility of the priority road is masked and the driver must inch forward to obtain a clear view. Here, visibility extended 60-70 meters, so that rule did not fit. The findings also did not show whether the appellant failed to observe adequately, misjudged the situation, or was unable to rule out an unforeseeable move by the priority vehicle.
