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?
20 years ago I asked my dad this and he said it was because if you pass on the right and then try to merge back into the left lane, any mistakes force you (or the other car) into oncoming traffic.
That’s good reasoning from your dad.
