Before changing lanes, check your rearview mirror for traffic and signal your intention to move to the right or left. Check blind spots by shoulder checking before changing lanes. Move into another lane only when safe. When changing across multiple lanes, it’s acceptable to make one shoulder check and signal to change over a number of lanes at one time, as long as the movement can be completed safely. If you must use mirrors only to check to the side and rear (unable to shoulder check), you can only change one lane at a time.
- Never change lanes at intersections.
- Signals and checks are required before moving away from a straight line such as when maneuvering past parked vehicles.
