SALT LAKE CITY -- Serious crashes involving motorists who run red lights are on the rise.
The Utah Department of Transportation released a report showing the number of crashes linked to people running red lights or stop signs and yield signs nearly doubled from 2006 to 2007.
Some motorists blame the problem on the length of yellow lights. But UDOT's Adan Carrillo says people need to simply pay more attention.
"Some people are perhaps assuming that they'll have enough time to cross the intersection, when they really don't. The time to start stopping is when the traffic signal is turning yellow," he said.
As for the timing on the lights, Carrillo says UDOT makes adjustments to try to synchronize the lights better. Federal law says the yellow lights must last between three to six seconds.
