Something requires extra attention. At an intersection, a flashing circular yellow means to take extra caution, and watch for traffic on the cross road (which has a flashing red light). A flashing red light is the same as a stop sign.
The researchers asked the drivers to stop when they saw a flashing yellow light and recorded their reaction time. The typical reaction time without texting was between one and two seconds, but while texting it increased to three to four seconds, regardless of whether the driver was typing or reading a text. The researchers also found that a texting driver was 11 times more likely to miss the flashing light.
