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?
No passing on the right law is combined with obligatory moving to the slower right if that lane matches your speed more.
This creates lanes with different speeds without the need for swerving between slower cars. And you can choose the lane(speed) you’re most comfortable with without being disturbed. This contributies to a more steady and safer flow of traffic.
