What is a common reason for changing lanes to the left on the interstate?

Changing lanes to the left on the interstate is often necessary due to construction activities taking place on the right side of the roadway. When construction is occurring, it can obstruct the flow of traffic and create a need for vehicles to navigate around the work zone to maintain safety and continue traveling efficiently.

Vehicles may need to move left to avoid obstacles, construction workers, or equipment, ensuring that they do not enter hazardous areas. It is crucial for drivers to be aware of construction signs and lane closure notifications, which can indicate when a lane change is needed to remain compliant with traffic regulations and to ensure the safety of all road users.

Options involving motorcyclists, traffic lights, and pedestrians do not typically apply to interstate driving, where high-speed traffic is often continuous without traffic signals or pedestrian crossings. Motorcyclists may travel on interstates, but they do not singularly dictate lane changes unless involved in a specific situation. Traffic lights are usually not present on interstates, which are designed for uninterrupted travel. Pedestrians are not typically found on interstates, as these roads are designated for use by vehicles only.
