Who is allowed full use of a lane?

Full use of a lane is typically allowed for vehicles that are legally permitted to operate on that roadway, such as cars, buses, and motorcycles. In many jurisdictions, cyclists also have the right to use a full lane, especially when there is no bike lane available. However, specific regulations can vary by location, so it's essential to be aware of local traffic laws. Additionally, emergency vehicles may also use a full lane when responding to incidents.
