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?

    In Europe (in my case the Netherlands, but it’s similar in surrounding countries) you cannot pass on the right and you can get fined for it. If you do pass on the right you’re taking a bigger risk because it is not expected.

    You can also get fined for staying in the left or middle lane for too long. But that’s somewhat rare. You can get away with it a bit to pass an extra truck (our trucks speed limit is slower) or if the right lane is full and slower than the lane to the left of it, but don’t drive excessively slow on the left. Especially on the Autobahn.

    I don’t know about the US, but in Germany the right lane is for getting on and off the high way, so going very fast there might be dangerous. It also just makes things less chaotic, traffic becomes more predictable and driving less exhausting.

    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.

    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.

    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.

        Generally your blind spot is larger on the right side(especially on tractor trailers) so it’s more likely to result in an accident.

          I think it’s also about being predictable and consistent. Generally, slow traffic stays to the right and fast traffic stays to the left. Breaking convention increases the chance of surprises and accidents.

    It’s more dangerous, if you’re about to pass a vehicle which limits your vision like a semi, box truck, delivery van, etc. and you can’t really see what’s ahead of you in the right lane, if you’re sitting in the left side of the vehicle, you won’t get good visibility until you are a decent amount of the way into the lane already.

    By the time you’re far enough In to see what’s ahead of you it may be too late to switch back if there’s a slow vehicle and you can rear end them. Passing on the left you can see what’s ahead by just moving close to the left and craning your head a bit.

    It’s actually not illegal in Texas. At least according to the cop that pulled me over for flashing my lights at someone doing 55 in the left lane when the speed limit was 70. He told me to just go around it’s not illegal.

    There are laws about passing on the right in Ontario:

    Section 150 of Ontario’s Highway Traffic Act states that using the right lane for passing a car in the left lane is legal as long as it can be done safely and one of the following conditions be met.

    The law states the car you’re passing must be making or signalling a left turn; that the road must be wide enough for two lanes of traffic in both directions; or that the highway be designated for one-way traffic only.

    https://www.theglobeandmail.com/drive/mobility/article-is-it-legal-and-safe-to-pass-in-the-right-lane/

    So it’s straight up legal on multilane highways. Which I didn’t know.

    Slower moving traffic should be on the right. So to pass someone you should need to move to the left lane. In some states in the US it is also illegal to be in the left lane unneeded, and I known of cops that would use the justification of being in the left lane to pull someone over even if it not illegal.

      Slower moving traffic should be on the right.

      I think this was the thought process, but it’s just not true in my experience. All the highways where I live are 4+ lanes. I go with with the flow of traffic. If I slow down to stubbornly not pass the person on my left, I’m really gonna fuck up the traffic flow.

      On a 2 lane highway, I’ll only pass on the right if the person in the left lane is completely oblivious that there are a line of people behind them and don’t move over.

        Yea the whole thing breaks down because people don’t keep right when they’re not passing. They pick a middle or left lane and squat in it at whatever speed they’re cruising at (assuming they’re even paying enough attention to maintain a steady speed) and clog everything up. If people were doing wht they were supposed to you wouldn’t be able to pass on the right because the people you’re passing would be occupying that space in front of you.

          Maybe, but I’m not completely convinced. It’s hard to apply that to all situations, especially when involving stop and go traffic, which is the majority of what I drove in until recently when I moved away from the city. Also, carpool lanes really fuck that up, too.

            A big part of why stop and go traffic happens in the first place is because people don’t follow it. At least on the highway where stoplights aren’t a factor.

              I’m just not convinced. It seems like stop and go traffic is caused by having 4 million people all leaving work at the same time while trying to use the same 3 highways. And merging lanes. That causes stop and go traffic as well.

                This is why it’s so important for people to follow the rules regarding lane usage in order to achieve as much throughput as possible.

    It’s to make the standard practice passing on the left, so people aren’t surprised by someone passing on the right. Since drivers sit on the left, another vehicle approaching on that side is easier to see.
