On a highway it is not a problem to overtake someone when you have two or three lanes available. But on a narrow roads this may be more problematic. Remember, you need a lot of space and time to overtake someone. You risk a lot when you start the maneuver with a limited field of vision. When you finish the maneuver pay attention to trailer as it may hit the vehicle behind you. When you start overtaking check the left mirror as cars like to overtake trucks.
