What should motorcyclists do before changing lanes?

The best practice for motorcyclists before changing lanes involves signaling, checking mirrors, and looking over their shoulder. This approach ensures that the rider is fully aware of their surroundings and can execute the maneuver safely. Signaling informs other road users of the rider's intention to change lanes, helping to prevent misunderstandings and accidents.

Checking mirrors allows the motorcyclist to assess the positions of vehicles around them and ensure that it is safe to make the lane change. Additionally, physically looking over the shoulder serves to eliminate blind spots where vehicles may not be visible in the mirrors. This comprehensive method significantly enhances safety on the road and is crucial for ensuring that a rider makes an informed decision when changing lanes.
