Root Cause

UK roundabouts are driven clockwise, and to exit at a right turn (3rd exit), drivers must be in the left lane before the exit and signal left, not right; the right lane is for going straight or turning left (1st exit).

中文

英国环岛是顺时针行驶，要右转（第3出口），司机必须在出口前进入左车道并打左转向灯，而不是右转向灯；右车道用于直行或左转（第1出口）。

Workarounds

  1. 93% success For a right turn (3rd exit) on a UK roundabout: approach in the left lane, signal left before the exit, and stay in the left lane while navigating. Example: `Enter the roundabout in the left lane, do not signal initially. As you pass the 2nd exit, signal left and check your mirrors. Exit into the left lane of the road.` 
    For a right turn (3rd exit) on a UK roundabout: approach in the left lane, signal left before the exit, and stay in the left lane while navigating. Example: `Enter the roundabout in the left lane, do not signal initially. As you pass the 2nd exit, signal left and check your mirrors. Exit into the left lane of the road.`
  2. 88% success Use GPS that supports UK roundabout guidance (e.g., Waze with UK settings). Example: `Set GPS to 'UK' mode and follow lane guidance; it will instruct 'At the roundabout, take the 3rd exit' without specifying left/right signals.`

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Staying in the right lane and signaling right on a UK roundabout causes confusion and potential collisions, as other drivers expect the right lane to go straight or turn left.

  2. 98% fail

    Using European or US roundabout rules (counterclockwise) on UK roads leads to wrong-way driving and serious accidents.

  3. 85% fail

    Assuming 'turn right' means using the right lane ignores that UK roundabout exits are numbered clockwise; exit 3 is a 'right turn' but requires left lane approach.
