Before the eclipse, state officials had described their traffic expectations as equivalent to that generated by the Bonnaroo Music Festival, the twice-a-season NASCAR Cup Series races at Bristol or the formerly-held Boomsday fireworks festival. "Maybe they should have considered a tsunami of traffic combining all three of those heavily attended events", the "News Sentinel" commented. The Tennessee Highway Patrol made sure that "trooper not on sick leave or military leave or pre-approved leave [was working" the day of the eclipse; the state DOT made sure its full complement of emergency-aid HELP trucks were available as well. Alert signs on the highways also warned motorists not to pull over onto the shoulders to watch the eclipse as it could increase the risk of dangerous accidents and block the path of emergency vehicles.
