It’s a hot day in July, and Jason Daniels is prepping for a day of driving from S.J. Smith’s Urbana, Ill., location. Daniels, who has been driving with S.J. Smith for eight years, is familiar with the safety requirements for driving the truck and delivering cylinders and refrigerated liquid cans. Today, however, he has company. He’s driving with Zack Kyer, compliance coordinator at S.J. Smith, for a full day of road testing.
