On a multiple-lane roadway, which lanes should you use for passing?

In general, the most accepted practice for passing on a multiple-lane roadway is to use the left lane. This is because the left lane is typically designated for faster-moving traffic and for overtaking slower vehicles. While some roadways may allow for passing in the middle lane under certain conditions, using the left lane is considered standard driving etiquette and safety practice.

On many roads, the right lane is often used for slower-moving traffic, and in some cases, for vehicles preparing to enter or exit the road. Conversely, passing on the right can be dangerous and is often against the law, except in specific situations where permitted, such as when the vehicle in the left lane is turning left and you can safely pass on the right.

Therefore, saying that both the middle and left lanes can be used for passing conveys that while the left lane is the primary lane for overtaking, there are instances where the middle lane may also be used, provided it is safe and legal to do so. This understanding of lane usage helps maintain smooth traffic flow and enhances road safety.
