Right Hooks and Helmets


"Do not make a sudden right turn after passing a bicyclist on your right. Instead, slow down and merge behind the bicyclist before turning."--New Mexico Driver Manual, pg. 26.

Almost took one on the chin yesterday morning, of the "ours" variety. While riding into the Conoco Hill intersection headed townbound, a lady in a small car quickly overtook me and made a sharp right onto Arkansas/38th and pulled into the Shell station. I did an instant turn inside her and followed her into the gas station.

The lady was apparently of the belief that bike lanes are equivalent to sidewalks, and that I had failed to wait for the WALK light. I explained how the law applies to bike lanes, which are travel lanes for the exclusive use of bicyclists, and that she in fact cut across my lane while I was in it. I admitted that the basic design is a confusing mess, i.e., a motorist is making a right turn from a center lane, and that we both needed to understand the layout and its limitations and avoid its pitfalls. I think she ended up believing that I was telling her good information.

Until we re-engineer bike lanes at intersections to ameliorate the hooking/crossing conflicts, possibly with protected intersection light cycles or signage such as the one I show here (not sure it is MUTCD compliant), they will be flawed designs, as they force a crisscross maneuver with a cyclist in a motorist's blind spot and frankly, the law is tough to sort out since a motorist making a turn from as close to the right hand edge as practicable (66-7-322) will be in the bike lane, which is a lane for the exclusive use of bicyclists. The clearest guidance is the basic idea (66-7-317) that you can't leave a lane until it is safe to do so. Indeed clear guidance is provided by the New Mexico Driver Manual, pg. 26: "Do not make a sudden right turn after passing a bicyclist on your right. Instead, slow down and merge behind the bicyclist before turning."  But given the usual motorist (and occasional police) confusion about the law, lack of training, and pure cluelessness, I conclude that you had better be on your situational awareness toes and up to date on your bike handling practice sessions. Don't put your safety in anyone else's hands.

Often, I leave the bike lane and occupy the appropriate travel lane as I approach an intersection in order to avoid this scenerio--its not "practicable" to put one's self in a dangerous situation. Riding slowly uphill on Diamond at Conoco Hill (is it now "Shell Hill"?) isn't one of those times, but it does leave me a little vulnerable to other people's mistakes. My typical low speed on cresting Conoco Hill works in my favor as far as safety. I look at it as good bike handling/situational awareness practice, and the occasional "teaching moment". But in general, one has to consider that being in a bike lane on a street with a lot of turning and crossing traffic, such as on Diamond south of Orange/Sandia, can be hazardous to one's health.

On another topic of occasional interest there is an excellent helmet article in the June hardcopy issue of Bicycling Magazine. Added later: the full story is now up on their web site. Title is "Senseless" and it is a...maybe...very well researched discussion on helmet design, testing standards, and current research into helmet design improvements and what is holding them back (fossilized standards, for the most part). If you want to learn something at the layperson's level about current helmet research, go buy a copy. Its really worth the price of the magazine. New designs in progressive foam compression and rotational acceleration management promise to make significant improvements in the old brain bucket, if these go into full production. Right now, Scott and Cannondale offer models with the "conehead" foam design, which is supposed to provide better management of deceleration by providing two interacting foams, one that compresses readily and one that is stiffer (see picture below). Go read the article and click over to the foam discussion on Randy Swart's for more authoritative information than I will put here in the interests of not violating copyrights or exceeding my limited expertise on the topic. Added later: Apparently, the Bicycle Helmet Safety Institute had a far less rosy evaluation of this article than I did. Go read their review here.

I won't get into all the political, ethical, and sometimes downright silly arguments pro or con helmets here. Decide for yourself. But one thing that seems to make sense from the Bicycling article is that the lack of correlation between decreased numbers of all brain injuries and increased helmet wearing can be explained by the decades-old helmet design, which is built to prevent one model injury, a very serious linear (ie., not shear rotation) impact mitigated by a very stiff foam. Lesser injuries, including concussion and shear damage, are still possible.

Seems like a sort of crappy post for National Bike Month on this site, but I'd rather you be safe than complacent. Keep the rubber side down and slip those punches!

Added later. Mike Prime emailed me at work, commenting " Did I notice correctly that the old “Bicyclists ride single file” signs on NM 4 near Bandelier have been removed and replaced with “Share the road” signs? I definitely noticed the Share signs. A million kudos to whoever made that happen. In my experience, that change makes a big difference in attitude for many motorists. I don’t know if the change happened all the way up into the Jemez. I’ve not been that way recently."

Bryan Lally said the signage continues into the Jemez. I suspect it would be the State District Engineer responsible. That's definitely good news.

Radio Hill I think is the current grass roots effort, probably failing, to rename Conoco hill.

Khal said...

I like that.

There are still a few "stay right ride single file" signs on 4, but not as many, and the Share The Road additions are nice. I first noticed them on my ride on Easter (which ended with me giving a police report...from an incident on West Jemez, not 4...)

Hey Khal,

I haven't read the Bicycling magazine article on helmets, but in my previous life as an amateur WW1 historian, I studied the British Brodie steel helmet. What I learned was that when an effective helmet is introduced, the numbers and severity of head injuries always increase. The British Army were appalled that the helmets didn't seem to work and commissioned a study. The study the army did showed that the increase in wound severity coincided closely with a reduction in deaths. So the helmets were substituting mortal wounds with survivable wounds. I suspect a similar thing is happening with cyclists.

Khal said...

Hi, Ian

I also suspect an increase in reporting.

ssportsman said...

Hi Khal,

another study has been released which concludes that helmet laws do not reduce head injuries..

Khal said...

Hi, Scott. Thanks for the link. Its worth reading, if only because the article is more complex than at first blush the title would suggest.

Hi Khal,
I just wanted to share a near-miss right hook that occurred to me on Sunday. It was my first real road ride of substance, and I had ridden out to the Bandelier turnoff and back to town. I was on Diamond in the bike lane when a woman in a small black Honda right-hooked me as she pulled into the Baptist Church parking lot from the first entrance. I followed her to her parking spot and kindly talked to her about how she very nearly caused me to have an accident. (As a side-note, she was on her phone, and she had a baby in the backseat.) The first thing she blurted out was, "I thought I beat you." Well, yes indeed, you did "beat" me, but if we had collided, your car surely would have won. "I was being tail-gated," was the second thing she stated. Well, you have brake-lights and turn-signals, there was no need to try to rush past me into the parking lot. I mentioned to her that I, too, am a Mom, and that if we had collided, it surely would have been a not-so-god Mother's Day for either of us. I asked her to keep in mind that cars are thousands of pounds heavier than a person on a bike, and that the next time she finds herself in that situation that she yield to the cyclist to prevent a possible catastrophe. I felt good about taking the time to talk to her, and I hope that she'll consider it next time she is in that position.

I had read your right-hook post, and it had been on my mind during the ride. Just glad we didn't actually make contact.

Khal said...

I too am glad you didn't make contact. Talking in a civil manner with the motorists may be a good way to educate the folks around here.
