綠燈信號是準許通行信號。按《交通安全法實施條例》規(guī)定：綠燈亮時，準許車輛、行人通行，但轉彎的車輛不準妨礙被放行的直行車輛和行人通行。

A green signal is a permit to permit. According to the "Traffic Safety Law Implementation Regulations" provisions: when the green light is on, the vehicle and pedestrian traffic, but the turning of the vehicle are not allowed to impede the release of the vehicle and pedestrian traffic.

黃燈信號的含義介于綠燈信號和紅燈信號之間，既有不準通行的一面，又有準許通行的一面。黃燈亮時，警告駕駛人和行人通行時間已經(jīng)結束，馬上就要轉換為紅燈，應將車停在停止線后面，行人也不要進入人行橫道。但車輛如因距離過近不便停車而越過停止線時，可以繼續(xù)通行。已在人行橫道內(nèi)的行人要視來車情況，或盡快通過，或原地不動，或退回原處。
