夜考燈光變化及注意事項

夜考被抽到的概率很高,如果抽到,也不要過度緊張,就當(dāng)提前開車上路。最關(guān)鍵的還是要保持鎮(zhèn)定,只要將平時練習(xí)的成果表現(xiàn)出來,就沒問題了。那么,夜間開車如何掌握路面情況?夜間開車燈光變化有何含義?下面小編為大家整理了夜間駕駛的一些常識,供大家參考學(xué)習(xí)!

燈光變化的含義

1、燈光投射距離由遠變近

表明汽車駛近或駛?cè)肷掀碌馈Ⅰ偨睆澔驅(qū)⒁竭_起伏坡的低谷地段

2、燈光投射距離由近變遠

表明汽車由陡坡進入緩坡或由彎道駛?cè)胫本

3、燈光離開路面

前方可能出現(xiàn)急彎或面臨大坑或正駛上坡頂

4、燈光由路中移向路側(cè)

表明前方出現(xiàn)一般彎道

5、燈光從道路的一側(cè)掃移到另一側(cè)

表明前方是連續(xù)彎道

6、前方路面出現(xiàn)黑影

情況一:駛近時逐漸消失,表明路面上有淺小凹坑

情況二:黑影不消失,表明路面上有深大凹坑

對比一:燈光明亮或暗淡

燈光明亮:在路燈亮光較強、平坦、寬闊的道路上行駛,可按正常操作方法行駛,如道路狹窄、轉(zhuǎn)彎、過橋或村莊時,應(yīng)減速變光,小心通過。

燈光暗淡:夜間在陌生或光線暗淡的道路上行駛時,對前方情況辨別不清,應(yīng)降低車速,對路邊的交通標(biāo)志、電線桿、樹木等物體和地形加以判斷。

對比二:有無月光

明月皎潔:借助月光對地面的反射,走灰不走白,遇黑就停車。因為月夜路面為灰白色,在湖、河邊沿行駛時,應(yīng)特別注意,勿將水當(dāng)路。行車途中,若發(fā)現(xiàn)前面突然變黑,就可能有障礙或急轉(zhuǎn)彎地方,應(yīng)減速或停車察明情況后通過。

無月夜:路面為深灰色,路基外為黑色。

對比三:特殊天氣

雨后:路面為灰黑色,凹凸、泥塘、坑洼為黑色,積水處為白色。

雪后:車轍為灰白色,通過較多車后為灰黑色。
