We checked with his students to see if the message is clicking.”Yes,” said Tiffanie Bridges, a sophomore who has her learner’s permit. Her classmate, Josh Gray, agreed and told us he looks out for anyone he is riding with. “I do. I make sure everybody else does, too,” said Gray.But student Nic Bishop wasn’t afraid to be honest with us about forgetting.”No, it’s just not the first thing that comes across the mind,” said Bishop.His answer could explain statistics from the state Bureau of Highway Safety.
