My son was in an accident his break line broke he hit 2 cars and took out a shrub. The airbag deployed and my son was trapped in truck for about 5 min with dust. He woke the homeowners up to let them know what happened.When cops came they never searched his truck they searched him nothing was found.I did receive the police report.The prob cause was glossy eyes and he failed the lifting of the leg test that was given in the middle of the hill. No odoor of any thing.Bac was .00 in the field and at the station.there was only a urine test given and came up marijuana.He admitted to smoking 5 to 6 days prior.I talked to 3 people at the scene and all 3 say there were no signs.2 of the witnesses were the homeowners .
