Linwood Laughy said based on his calculations, he doesn't believe the megaloads can meet ITD's standard of not delaying traffic more than 15 minutes. "I've calculated it out," he said. "One stretch they'd have to go 49 mph."

Attorneys for ConocoPhillips are now cross-examining Laughy, asking him if he has an engineering background or has ever worked with an oversized load. He answered no. "You're not an engineer," attorney Erik Stidham said to Laughy. "Is this just one of those situations where you look at it and you just say, 'I don't understand how this is going to work?'" Laughy responded that he can use a calculator and Google. "I can certainly handle the measuring tape pretty well," he said.

Stidham questioned whether a misplaced decimal in an ITD chart, in data provided by ConocoPhillips, might have thrown off Laughy's calculation to yield the 49  mph result; Laughy said it's possible. "I looked at your data, and it said you were going to travel 8.2 miles in 10 minutes," Laughy told Stidham. "I took your word for it."
