- Check your mirrors to find a good gap in the lane you want to move into.
- Check over your shoulder to make sure there are no smaller vehicles, like bicycles, in your blind spot. Signal that you want to change lanes.
- Double-check that the way is clear, watching for fast-approaching vehicles from behind or from two lanes over on a multi-lane road.
- Keep your current speed or gently increase it as you change lanes.
- Unnecessary lane changes or weaving between lanes, especially in heavy traffic or bad weather.
- Changing lanes close to or within an intersection, as this can cause confusion and increase the risk of accidents.
