Traffic Optimization: Cyclists Should Roll Past Stop Signs, Pause At Red Lights 490

Lasrick writes: "Joseph Stromberg at Vox makes a good case for changing traffic rules for bicyclists so that the 'Idaho stop' is legal. The Idaho stop allows cyclists to treat stop signs as yields and red lights as stop signs, and has created a safer ride for both cyclists and pedestrians. 'Public health researcher Jason Meggs found that after Idaho started allowing bikers to do this in 1982, injuries resulting from bicycle accidents dropped. When he compared recent census data from Boise to Bakersfield and Sacramento, California — relatively similar-sized cities with comparable percentages of bikers, topographies, precipitation patterns, and street layouts — he found that Boise had 30.5 percent fewer accidents per bike commuter than Sacramento and 150 percent fewer than Bakersfield.' Oregon was considering a similar law in 2009, and they made a nice video illustrating the Idaho Stop that is embedded in this article."

            The California Stop is a real thing, it's when you slow as you approach the stop sign, see that there's nobody around, and then proceed through. It's an artifact of the fact that at certain times of the day, certain roads are very empty, which in turn is the result of a large state with lots of roads.

      Never mind that the laws have little to do with interactions between cyclists and motorists, the attitudes of one towards the other has much more to do with it. In the same way that you can't legislate morality, passing a bunch of laws giving cyclists a different set of rules than motorists isn't going to necessarily make things any safer for cyclists. In fact, it might very well make things less safe overall, if motorists don't like the laws enacted, or like cyclists themselves much in the first place. Eve

    It doesn't matter if you SHOULD have right of way. It matters if someone will see you and stop (and not run you over). When you come up to any dangerous intersection (or any intersection) you should slow down, look to make sure you're not going to get plowed into, and THEN go.

    As a cyclist, you might be going 30 KPH easily, but you're much easier to miss for a motorist because you are so small, and you might come at an odd direction (most people aren't used to making sure there's no cyclists on the shoulder).

      There is nothing in the regulations that say treating a stop as a yield or a red light as a stop sign somehow gives you any additional right of way. All it means is that you don't have to wait as long to determine if the intersection is safe to cross.

      The Idaho Stop / California Roll is all about going slow enough that you can gauge the traffic heading towards the intersection for the other directions to determine if it is safe to move. A stop sign simply 'forces' cars to stop even if it would be otherwise safe to only slow down to a few miles an hour. And a red light forces cars to stop even when you can see for miles in both directions that there is nothing coming.

      A car moving slowly can easily kill or do heavy damage to a pedestrian (or another road user). Whereas a bicycle has a much smaller cross section, lower kinetic energy, and a rider that is far more likely to come off badly no matter how small the object/person is that they collide with.

      You can't be serious saying it is more dangerous to give way at slow speed versus coming to a complete stop and then having to huff and puff back up to speed, while simultaneously being overtaken with inches to spare by a bunch of impatient motorists because you can't outpace them.

      In fact the article gives clear statistics showing the exact opposite. Just about every cyclist I know treat 'right of way' as synonymous to 'enter at your own risk'.

If you can't see around the corner when approaching a stop sign slow down to around walking speed so you can stop if a car runs right through the intersection, which I've seen some do, even at a 4-way stop. Traffic lights you have to use you're judgment. I wouldn't go making any left hand turns across multilane roads against the light, unless the road was completely deserted.

        The "Idaho Stop" allows you to go when other traffic has to stop. Anybody coming behind you has to stop where you can go.

And you would wait behind the bicyclist stopped at the stop sign and not pull up next to them before coming to a stop and then pulling out as soon as you decided it was clear to do so, even though the bicyclist got there first and was just starting? If such is the case, you are so rare that when I used to ride bike a lot I never saw any drivers like you.

    • It doesn't matter if you SHOULD have right of way.

      You misunderstand Idaho Stop, as it never gives right of way to cyclists. The most they get is right of movement when there is no conflicting traffic, in other words when there is no right of way issue. If conflicting traffic is present then that traffic always has right of way over the cyclist at a stop sign or red light.

      It certainly doesn't make cyclists "own the road", as you put it, since that's synonymous with having right of way.

      Actually, bicycles that don't roll through intersections are more likely to hold up traffic behind them, while having motorists make unsafe overtaking manoeuvres to get around them right near the intersection itself.

      Any time someone uses a car (or any object for that matter) to intentionally cause an accident, that person is open to prosecution. Whether it be a douche bag pulling in front of a 30 bike peloton and slamming on their brakes, or opening their door while queued up a traffic light just to stop a motorcyclist from filtering through to the front. That shit is illegal simply because it is someone intentionally causing harm to another person. Just like someone running over an old lady that was taking too long to cross the street; the light goes green on them, and a driver thinks 'fuck it I have right of way, I'll just blow right over the top of her in my oversized SUV'. They definitely don't have the 'right of way' to injure or kill someone.

      I'm sure there are many assholes out there who just claim they did what they did for some other idiotic but 'unintentional' reason. But, that doesn't make it right, nor does it guarantee a jury will believe them.

      Maybe I'm misreading your post, but If you can't see that road safety isn't just about blindly following regulations, then you should definitely not be driving on the road. Otherwise, it is only a matter of time before you end up in court wondering how you got there.

    Stop sign: Slow down, low both/all ways, proceed if clear. Otherwise follow normal traffic rules.
    Yellow light: Stop unless you're already in the intersection
    Red light: Stop and don't go until your turn in normal traffic

    Outliers: Crosswalk: Proceed unless there is a walker. Stop then proceed otherwise.
    Flashing yellow: Slow down, low both/all ways, proceed if clear
    Flashing red: treat like stop sign.

    Pretend like you are new to a bike and you will be much safer and people will hate you so much less. One thing you can do, unless you are a very serious cyclist, is avoid getting the pedals which require cycling shoes. If one is not clipped in, imo, one is less likely to break laws and be a douche about existing ones. For people riding 50+ miles a week, I can understand why they want them. However those are not the people who cause problems for everyone else (in my experience).

Running red lights is still illegal, and fines are much higher than other states/cities and are enforced. Bicylist are also allowed to make rolling stops at stop signs. Which means slow down, to make sure the intersection is safe, and yield to other vehicles, and if there is no one, just proceed. Blasting through a stop sign is a big no, too.

    I didn't know that cyclists stopped for stop signs anyway. I was in Cape Cod, which has some great bike trails (my daughter and I use them). I was driving at the time though, stopped where the bike trail crosses the road, looked around, saw nobody, and proceeded. Somebody went flying across, and the only saving grace was that he swerved to avoid a collision (and I hit the brakes of course). There was a stop sign on the bike path, but at the speed he was going he couldn't have stopped or slowed down for it.

    I bike, though not for commuting, and there are a few rules you have to follow. Yes, it's a pain to stop once you've got some speed up, but it's better than getting killed. I'm not saying most cyclists do this, but I felt like blowing off some steam it.

    As for the Idaho law, I'm not sure it would work everywhere. What does yield mean? You're supposed to slow down, but by how much? For some cyclists it means glance around quickly before flying through the intersection. As it is, most cyclists don't completely stop at a stop sign, including me, but you've got to use some judgement. Clear view of the intersecting road? Maybe slowing down enough is ok. Blind corner or something? Stop all the way. And the only way to know an intersecting road can be seen clearly is if you've ridden through that area before.

    TFA is a pile of crap, with no evidence to support its conclusions.

    Rationale #1: "Yield" is just as safe as "Stop", and saves energy for bikers. Problem: It saves energy for cars, too, and if used with cars as bikers use it (slowing to 5MPH), should be just as safe for cars.

    Rationale #2: Treating a stoplight as a 1-way stop sign is just as safe for a bike. Problem: Why not treat those stoplights as "Yield" signs, too, if those are safe? Why can't motorists adopt the same not-so-strict rules as bikes, for the same benefits? Also, the lower speed of bikes, combined with the possibility of blind corners and drivers that see the green light long before the biker, seems likely to make this very dangerous in *some* areas, particularly in the dark.

    Rationale #3: Eliminate the laws cyclists don't follow, and they'll follow all the rest. Problem: "The rest" include the ones we're changing, because they don't follow them. ie. If they don't stop at stop-signs when there are cars waiting, NOW, why would they do so when they're effectively changed to Yield signs? If cyclists really have figured out the "Idaho Stop" on their own, why aren't the accident rates equally as low, and/or falling quickly?

    Rationale #4: "the low-traffic routes that are safer for bikes are the kinds of roads with many stop signs." Problem: Low traffic routes are safer for cars, too. Sounds like we're changing the laws to encourage devaluing a number of roads for cars, in order to provide a biker's oasis.

    Rationale #5: "he found that Sacramento had 30.5 percent more accidents per bike commuter and Bakersfield had 150 percent more". Problem: The improvement over Sacramento sounds like a very tiny improvement which could have been caused by any number of minor variables. Additionally, the HUGE GAPING DISPARITY between Sacramento and Bakersfield, both cities without these rule changes, clearly shows that the Idaho stop rules aren't causing these differences, and there's far too much uncontrolled variability to draw any conclusion about the Idaho method.

    Where is the evidence... ANY evidence, that this is a positive change?

For God's sake, stop researching for a while and begin to think!
