Lane Changing
Lane changes are safe only after mirrors, head checks and signalling. Continuous lines and areas near intersections often prohibit lane changes.
Key Rules
- Check mirrors and blind spots before each lane change.
- Signal early and move only when there is a safe gap.
- Do not cross a continuous line where it prohibits changing lanes.
- In congestion, sudden lane changes increase side-impact risk.
Common Mistakes
- Changing lanes using only the rear mirror, with no head check.
- Signalling and moving at once, with no time for others to react.
Practical Example
You want the right lane to exit. Indicate, shoulder check, see a vehicle in the gap and wait until it passes before moving.
Quick Check
- What order: mirror, blind spot or signal first?
- When does a continuous line prevent a lane change?
- Why does the blind spot matter?
