The dots are spaced to keep cars two seconds apart when traffic is moving at the speed limit - 60 mph, she said.
When traffic is moving more slowly, vehicles can be closer because they don't move as far in two seconds. But when speeds were slower during the heavier traffic Saturday, drivers maintained the 160-foot distance, causing long backups behind them, Murdock said.
