The 12 o'clock method is a guideline used primarily for navigating roundabouts, specifically concerning lane choice based on the intended exit.
Understanding the 12 O'Clock Method
This method simplifies choosing the correct lane by visualizing the roundabout as a clock face. The central concept revolves around the location of your exit relative to this imaginary clock:
-
12 o'clock: Represents the exit directly opposite your entry point on the roundabout (straight ahead).
-
Lane Selection: According to the provided reference, the lane you should choose is determined by the clock position of your exit:
- Left-Hand Lane: Select this lane if your exit is at 12 o'clock or before.
- Right-Hand Lane: Select this lane if your exit is at 1 o'clock or after.
How to Apply the 12 O'Clock Method
Here is a step by step guide on using the method to navigate roundabouts:
- Visualize the Clock: Imagine a clock superimposed on the roundabout with your entry point at the 6 o'clock position.
- Identify Your Exit: Determine the clock position of your desired exit.
- Choose Your Lane: Based on your exit's position, select either the left-hand lane (for 12 o'clock or earlier exits) or the right-hand lane (for 1 o'clock or later exits) as you approach the roundabout.
Practical Example
Imagine you are approaching a roundabout:
- Example 1: 11 o'clock exit. You should be in the left-hand lane since 11 o’clock is before 12 o'clock
- Example 2: 12 o'clock exit. You should be in the left-hand lane since this exit is at 12 o'clock.
- Example 3: 2 o'clock exit. You should be in the right-hand lane since 2 o’clock is after 1 o’clock.
Key Takeaways:
- The method is a simplified way to choose the correct lane based on the position of your exit on the roundabout.
- Using this method is important for efficient and safe driving on roundabouts.
- The reference states if the exit you need to take is at 12 o'clock (straight ahead) or before, you would choose the left hand lane on approach to and on the roundabout. If your exit is at 1 o'clock or after, you would choose the right hand lane.
