(Portage) A Deforest teen was charged with First Offense Operating While under the Influence following a two-vehicle rollover crash in Portage Sunday. Just after 2pm, police responded to the 1000 block of West Wisconsin Street where a Mazda struck a Toyota van which caused it to rollover and block the lane of traffic. Authorities say bystanders were able to assist the four children and operator of the Toyota. Only the driver sustained minor injuries but was not transported by EMS. The 17-year-old driver of the Mazda and an 18-year-old male passenger from Windsor were not injured. The investigation revealed that the Toyota was traveling east on West Wisconsin when the Mazda failed to yield the right of way. The Toyota hit the front driver’s side of the Mazda causing it to roll and come to rest on its side. Police say while investigating the crash scene, suspected marijuana was located inside the Mazda. They say the 17-year-old also displayed signs of drug impairment and a field-sobriety test was conducted. The teen was subsequently taken into custody for Operating a Motor Vehicle while under the Influence of a Restricted Controlled Substance Causing Injury First Offense. The driver was also cited for Possession of Marijuana with possible additional citations.
