Pedestrian signals are used to inform pedestrians when to cross a road. Most pedestrian signal heads will have two lights: a 'walk' light (normally a walking human figure, typically coloured green or white) and a 'don't walk' light (normally either a red or orange man figure or a hand), though other variations exist. [39]
Once the pedestrian crossing phase comes to an end, the countdown indicator reaches "0", and the pedestrian signal changes back to the non-flashing upraised hand (don't walk). Then the vehicle signal head returns to the dark state, and vehicle traffic has the right of way, until the signal is reactivated.
The bottom window, previously showing the walking animation, sometimes becomes a countdown display in red, although there are many versions of xiaolüren pedestrian lights where countdowns are absent and not build in to red lights, red light timers also break more easily than green light timers, as the devices are possibly programmed to believe ...
Some pedestrian signals integrate a countdown timer, showing how many seconds are remaining for the clearing phase. In the United States, San Francisco was the first major city to install countdown signals to replace older pedestrian modules, doing so on a trial basis starting in March 2001. [68]
At signalized intersections, crosswalks may have pedestrian signals which display symbols to mandate when pedestrians may cross the street. State road rules in the United States usually require a driver to yield the right of way to a pedestrian crossing a road when the pedestrian crosses at a marked crosswalk or an unmarked crosswalk.

This three-arm signal controlled junction has three vehicle phases (A, B and C) and a pedestrian phase (D). The phases operate together in three stages (1, 2 and 3). Moving phases are shown in green and stopped phases are shown in red. Phases are indications shown to traffic on traffic signal aspects (a single light on a signal head). For ...
Traffic light in Chelyabinsk, Russia showing a green light with a digital countdown (in the centre aspect) of the time left until the signal switches to amber. Red light running occurs when a motorist enters a junction any time after the signal light turns red unless a legal turn on red manoeuvre is completed. [3]
In New Zealand, where they drive on the left, when a road is given a green light from an all direction stop, a red arrow can continue to display to turning traffic, holding traffic back while the pedestrian crossing on the side road is given a green signal (for left turns) or while oncoming traffic goes straight ahead and there is no permissive right turn allowed (for right turns).
