Why is it illegal to pass someone on the right on the highway in the US? In Canada if there’s a three lane highway which, in my case, isn’t very prominent, there’s really no law that enforces it, it’s more of a respect thing here on two lane highways both ways if someone is going slow in the left lane to go into the right but I’m just curious as to why it’s actually enforced in the US?
It probably depends on the state, but in mine the restriction on passing on the right is for two-lane or unmarked roads. It is not applicable to multiple lanes in the same direction.
