根因分析
英国环岛要求顺时针行驶；要右转（即第三个出口），驾驶员必须在左车道进入（除非道路标志另有指示），在通过第一个出口后打右转向灯，并从左车道驶出。错误使用右车道可能导致碰撞。
English
UK roundabouts require clockwise travel; to turn right (i.e., take the third exit), drivers must enter in the left lane (unless road markings indicate otherwise), signal right after passing the first exit, and exit from the left lane. Using the right lane incorrectly can cause collisions.

-
To turn right at a UK roundabout: approach in the left lane (unless signs indicate otherwise), signal left after passing the first exit, and exit from the left lane. For multi-lane roundabouts, follow lane markings (e.g., 'right turn only' arrows).
-
Practice using a driving simulator (e.g., City Car Driving) with UK road settings, or take a short lesson with a UK driving instructor to learn roundabout rules.
-
If unsure, treat the roundabout as a 'give way' junction: yield to traffic from the right, and use the left lane for all exits unless signage directs otherwise. Never assume lane usage from home country.
无效尝试
常见但无效的做法:
-
80% 失败
In the UK, traffic flows clockwise; the left lane is for turning right (third exit) unless markings indicate otherwise. Using the right lane for a right turn forces other drivers to swerve.
-
60% 失败
Signaling right before entering is incorrect for a right exit; drivers should signal left when exiting, not right when approaching. Wrong signaling confuses other road users.
-
70% 失败
Exiting from the right lane cuts across traffic in the left lane; UK law requires exiting from the left lane unless road markings explicitly permit otherwise.
