道路交通信號燈是交通安全產品中的一個類別，是為了加強道路交通管理，減少交通事故的發生，提高道路使用效率，改善交通狀況的一種重要工具。適用于十字、丁字等交叉路口，由道路交通信號控制機控制，指導車輛和行人安全有序地通行。下面小編結合交通信號燈的圖片為大家介紹其分類和功能。

1、綠燈信號

1, green signal

綠燈信號是準許通行信號。按《交通安全法實施條例》規定：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.

2、紅燈信號

2, red light signal

紅燈信號是絕對禁止通行信號。紅燈亮時，禁止車輛通行。右轉彎車輛在不妨礙被放行的車輛和行人通行的情況下，可以通行。

Red light signal is absolutely prohibited traffic signal. When the red light is on, it is forbidden to travel. The right turn vehicles can be used without obstruction of the vehicle and pedestrian traffic.

紅燈信號是帶有強制意義的禁行信號，遇此信號時，被禁行車輛須停在停止線以外，被禁行的行人須在人行道邊等候放行;機動車等候放行時，不準熄火，不準開車門，各種車輛駕駛員不準離開車輛;自行車左轉彎不準推車從路口外邊繞行，直行不準用右轉彎方法繞行。

3、黃燈信號

3, yellow light signal

黃燈亮時，已越過停止線的車輛，可以繼續通行。

When the yellow light is on, the vehicle has crossed the stop line.

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，可以繼續通行。已在人行橫道內的行人要視來車情況，或盡快通過，或原地不動，或退回原處。

The meaning of the yellow light signal is between the green light and red light signal, which is not allowed to pass, but also to permit the passage.

4、閃光警告信號燈

4, flashing warning light

為持續閃爍的黃燈，提示車輛、行人通行時注意瞭望，確認安全后通過。這種燈沒有控制交通先行和讓行的作用，有的懸于路口上空，有的在交通信號燈夜間停止使用后僅用其中的黃燈加上閃光，以提醒車輛、行人注意前方是交叉路口，要謹慎行駛，認真觀望，安全通過。在閃光警告信號燈閃爍的路口，車輛、行人通行時，即要遵守確保安全的原則，同時還應遵守沒有交通信號或交通標志控制路口的通行規定。

For the continuous flashing yellow light, prompting the vehicle, pedestrian traffic, attention to the lookout, confirmed by the safety. The lamp has no control traffic in advance and given to the role and suspended in crossing over, some of the traffic signal lights at night stop after use only the yellow light and flash, to remind the vehicles and pedestrians pay attention in front of the intersection, be careful driving, careful wait-and-see, safe passage.

Two important intersection crosswalk lights in crossing the stream of people more. The lamp for the roadway, and the vertical center of the road.

人行橫道燈信號有綠燈亮、紅燈亮兩種信號，其含義與路口信號燈信號的含義相似，即綠燈亮時，準許行人通過人行橫道;紅燈亮時，禁止行人進入人行橫道，但是已經進入人行橫道的，可以繼續通過或者在道路中心線處停留等候。
