When is it legal to pass another vehicle on the right?

Passing another vehicle on the right is legal when the vehicle being passed is making a left turn. This is a common scenario where the left-turning vehicle is preparing to enter a side road or driveway, and it creates an opportunity for the driver in the adjacent lane to safely maneuver around it without crossing into oncoming traffic.

In this situation, the rules of the road allow for this type of passing because it helps maintain the flow of traffic and is considered safe as long as there is sufficient space. It's important for drivers to always be aware of their surroundings and ensure that the maneuver can be executed without endangering other road users.

In contrast, other conditions like the road needing to be wide enough, being on a one-way street, or specific speed limits do not inherently justify passing on the right. These factors might influence the safety of passing, but they do not create legal grounds for doing so unless the conditions specify that another vehicle is engaged in a left turn.
