Bus expert witness Charles Scalia, owner of Scalia Safety Engineering of Madison, testified that the 78-year-old driver of a bus that slammed into an overturned semitrailer truck, killing five people 18 months ago, had plenty of time to stop if his recognition of the hazard and reaction time were normal.
According to the Winona Daily News, Scalia testified:
Normal reaction time for a driver seeing a hazard is 1.6 seconds, including time to perceive a problem, consider a course of action and start the reaction, Scalia said. The vehicle response time is typically .3 seconds, he said, making for a total reaction time of 1.9 seconds.
