a vehicle is overtaking you. what must you do?

When a vehicle is overtaking you, you must keep to the right to make it easier for the overtaking driver, maintain your speed without accelerating, and avoid obstructing the overtaking maneuver. You can reduce your speed slightly if needed to facilitate a safe overtaking, but you must not increase your speed. Additionally, try to keep a good distance from the vehicle in front so the overtaking vehicle has space to return to the lane safely. If there is a hard shoulder, you may use it to assist the overtaking vehicle, but you are not obligated to move onto it. Avoid any actions that could endanger the overtaking vehicle or obstruct the maneuver in any way.
