Is it permissible to proceed through a yellow light?

[KinsleyLee]

According to relevant regulations, traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. However, there are no explicit regulations specifying whether vehicles can proceed when the light changes from red to yellow or from green to yellow. Additional information is as follows: 1. Classification of traffic signals: Traffic signals are categorized into: motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator signals (arrow signals), lane signals, flashing warning signals, and railway crossing signals. 2. Scientific basis: Based on optical principles, red light has a long wavelength and strong ability to penetrate air, making it more noticeable than other signals, hence its use as a prohibition signal. Green is used as a passage signal because the distinction between red and green is the greatest, making them easier to differentiate (red-green color blindness is, after all, rare).
