Cyclists, stay to the … left?

Bicyclists are required under certain conditions to be “as far right as practicable”. Why would a cyclist be, or even want to be, to the left? It turns out there are many and various reasons why, and which are not only legal, but safer for the cyclist. Staying to the left can even be more convenient for other motorists, and improve traffic flow; with one such common situation described in detail here.

Scottsdale settles bicyclist injury lawsuit

There was a bunch of information published about a settlement between a bicyclist injured in 2014 and the city of Scottsdale; After much back-and-forth the city eventually settled the case for $120,000; significantly less than the $1M ask, but significantly more than the city’s earlier offer of $60,000.

The city staff reports mention the cyclist had (already) settled with the driver, presumably the driver’s insurance, and as this was a strike-from-behind they probably just accepted liability. The theory of liability with the city is they should have, but did not, provide a bicycle lane or shoulder.

It provides an look at the machinations of personal injury law that those of us on the outside don’t usually see. Continue reading “Scottsdale settles bicyclist injury lawsuit”

Bicycle Laws in the United States-Past, Present, and Future

Bicycle Laws in the United States-Past, Present, and Future is an ambitious, scholarly article written by attorney Ken McLeod, who also happens to be a member of LAB’s s Legal Affairs Committee. And has written much of the content available on LAB’s site relating to laws and legal matters, e.g. bike-law-university and the paper is reflective of the information there, just perhaps in a more technical/scholarly format.

Ride With Traffic

R5-1b (top) with R9-3cP plaque (bottom)
The most concise, least able to be misconstrued, message about which direction a bicyclist must operate, is “Ride With Traffic”, it’s the inscription on a R9-3cP plaque. But what is “with traffic”, or “the flow of traffic” or “the direction of traffic”? And why do we so often hear “ride right”, “bike right”, “Be a Roll Model: Ride on the Right” or some other clever-sounding catchphrase? Continue reading “Ride With Traffic”

Knowingly

The case of Trevor Clarke, an Ottawa Canada driver who was involved in a serious 2012 collision with a bicyclist while drunk, and then fled the scene raised quite a stir. According to news reports, the driver was convicted (by a judge, meaning this was for unstated reasons not a jury trial) in 2015 of “impaired driving causing bodily harm”, but was found not guilty of leaving the scene because the judge said. “I am left in a reasonable doubt about whether Mr. Clarke knew or was wilfully blind to having collided with a person, precisely because he was so drunk. He cannot, therefore, be convicted of this offence”.

Another MM decision; MM card is no defense to DUI

About two weeks after MEDICAL MARIJUANA NO DEFENSE TO DUI CHARGE, another Arizona Court of Appeals Div 1 decision came down that is related to and as expected consistent with their earlier opinion. Please visit that link for more info and scroll down to “Another Court of Appeals Case 11/4/2014”.

The driver of a vehicle


This article is very similar to: bicycles-arent-vehicles

A bicyclist is considered the driver of a vehicle for the purposes of the transportation code, A.R.S. Title 28.; and at the same time, a bicycle is excluded from the definition of vehicle.

More fully, a bicyclist is “…granted all of the rights and is subject to all of the duties applicable to the driver of a vehicle…” §28-812, which goes on to state specifically which Chapters of Title 28 these rules apply to, 3, 4 and 5 which are the Rules of the road, DUI, and Penalties, respectively.

Are Cyclists Required to Carry ID? Are Pedestrians? Updated 2014

[2/23/2019 update: see story about 12 y.o. Hilde Kate Lysiak says Marshal Joseph Patterson stopped her as she was biking in Patagonia, Arizona. Various issues: asked her for identification?. “failure to comply with lawful order”? “illegal to video record”? ID?  ]

[2/17/2015 update: Officer Ferrin of the Ore incident has resigned. ASU released a chief’s letter and an independent investigation commissioned by ASU performed by Investigative Research Inc.  (apparently through public records?) I would describe as scathing, and that corroborates most of what I thought/said below, see the lengthy news story on azcentral — There is no law requiring peds to provide an ID card (in other words his saying “Let me see your ID or you will be arrested for failing to provide ID” is wrong, see  Arizona v Akins, below); there was no ‘jaywalking’, see link below to the actual jaywalking laws; there was probably no probable cause for the arrest; he didn’t “almost run her over”; 5 days earlier the officer had a similar (but non-physical) power-trip incident over a crosswalk. and on and on. The transcript, see below, confirms Officer Ferrin doesn’t understand the (ID) law]

[2015 update to the Ore incident: in an apparent about-face, ASU has moved to terminate Officer Stewart Ferrin over the matter; apparently as the result of an un-released independent review by an “outside agency”. ]

In 1999 Tucson bicyclist Enol Daniel Ortiz Jr. spent the night in jail for not having ID on him. It appears that now (since 2003) cyclists and other non-motorists have no legal obligation to carry identification.

The update in 2014  is due to the unusual case of Ersula Ore, an English professor at ASU. She was apparently “jaywalking” when she got into an altercation with ASU police. From what I can see this on College Ave, somewhere north of University Dr. This is a public street in the city of Tempe (there seems to be some confusion and many erroneous comments about this; this location is not “on campus” or somesuch). Tempe’s codes for pedestrians are here; ASU is NOT in the “central business district”, the more-restrictive “jaywalking” code only applies in the CBD so it leads me to wonder if she was really jaywalking at all. Jaywalking codes, real or imagined, are frequently used to assert superiority by motorists (the police officers were driving cars) over pedestrians.

Arizona court ruling upholds DUI test for marijuana

[ 4/22/2014:  in what is presumably the final update, the Arizona Supreme Court ruled (here is same doc archived by azcentral) 4-1 that  it is not a DUI violation to be driving with the non-impairing marijuana metabolite in their bodies. In other words, the reversed the Court of Appeals ruling. Here’s a pretty good news item wrapup from the New Times. The lone dissenter offered a detailed analysis as part of the published opinion; I tend to side with her, that the majority overreached by concluding a flat ban, which is the plain language of the law, produces absurd results. But there you have it.]

This idea of any non-zero level of (a long list of) drugs, or their metabolites, being equated with driving impaired has always worried me; this recent CoA ruling affirms that this is proper. So, nothing to do with this case, i’m wondering if a decongestant, pseudophedrine (commonly found in many cold medicines) cause dui per 28-1381(A)3??? why or why not. I am chemistry challenged.

In the Court of Appeals, Div 1. No. 1 CA–SA 12–0211
STATE v. HON. HARRIS/SHILGEVORKYAN (if that link is dead findlaw0211). The caption of this case is a bit confusing,  the Real Party in Interest is Hrach Shilgevorkyan. Harris is the name of the Superior Court commisioner.

There are three ways to run afoul of Arizona’s DUI statue. The most common would be #2, BAC > .08 (referred to as drunk per se), typically anymore it is via blood evidence; another way is #1 being “under the influence… if … impaired to the slightest degree”, typically via field sobriety tests. The third way, and the one at issue here is #3, “While there is any drug … or its metabolite in the person’s body”. Continue reading “Arizona court ruling upholds DUI test for marijuana”

Court reinstates Scottsdale DUI test results

There was a CoA ruling recently in a long-running case that questioned the accuracy of one particular piece of lab equipment used in Scottdale’s crime lab involved with a handful of serious DUI cases.

CA-SA 13-0285 STATE v. HON. BERNSTEIN/HERMAN in the Arizona Court of Appeals, Division 1, was a so-called “special action” brought by Maricopa County Prosecutor Bill Mongomery. Continue reading “Court reinstates Scottsdale DUI test results”

Ruling: cyclists are required to satisfy nighttime lighting requirements even on the sidewalk

There’s a recent (7/11/2013) Arizona Court of Appeals District 1 (“Phoenix”) ruling Arizona v. Baggett  (full text via findlaw, or direct link from CoA, or google scholar) that affirms that bicyclists must use a headlight during nighttime, 28-817, not just when riding in the roadway, but also on the sidewalk. Cite case as:

State v. Baggett, 306 P.3d 81, 82 (Ariz. Ct. App. 2013)

By extension, other bicycle-specific rules (generally 28-813 through 28-817; so for example one-seat per person; the one-hand rule; stuff like that) would also apply to cyclists using the sidewalk; while those that specifically mention the roadway, e.g. 815A and B do only apply on the roadway. Look up the bicycle statutes at bicycle-laws.

This ruling adds to a very slender body of case law involving bicycle laws in Arizona; see also Maxwell v. Gossett, and Rosenthal v. County of Pima for the only other published (it’s not clear to me that Baggett is “published”?) cases I am aware of in the history of Arizona!

Is it illegal to cycle on the sidewalk in Phoenix?

There some mis-information floating around in the media, see e.g. yumasun.com and azstarnet.com sourced from something called “Howard Fischer Capitol Media Services”. It claims sidewalk cycling in Phoenix is illegal under city code; that is explicitly not part of the decision — so, i’m not sure where or why that was said. Here is the passage from the news article (my emphasis added): Continue reading “Ruling: cyclists are required to satisfy nighttime lighting requirements even on the sidewalk”

What exactly is an Inoperative Traffic Signal?

So this revolves around the law dealing with traffic signals that are “inoperative” 28-645C

C. The driver of a vehicle approaching an intersection that has an official traffic control signal that is inoperative shall bring the vehicle to a complete stop before entering the intersection and may proceed with caution only when it is safe to do so. If two or more vehicles…

So: 1) make a complete stop, and 2) proceed only when safe. Simple enough. But what does ‘inoperative’ actually mean?

 Arizona Bicycling Street Smarts

Adot’s AzBSS Puts it this way:

WHEN TRAFFIC LIGHTS DON’T TURN

Always stop and wait for red lights. You not only ensure your safety, but you also increase respect for cyclists as law-abiding road users.

But some traffic lights don’t turn green until they receive a signal …

If your bicycle doesn’t trip the detector, you have to wait for a car to do it, or stop and wait until it is safe to go through the red light. Going through the red isn’t against the law, because the light is inoperative (Arizona Revised Statutes 28-645).

 

 

Below the line is a bunch of semi-unorganized research that may or may not shed light on the subject!


 

PennDOT was, I believe, the first State DOT to adapt Street Smarts, from Chapter 9:

If your bike does not trip the detector, you have to wait for a car to do it, or else you have to go through the red light. Going through the red is not against the law, because the light is defective. Refer to Sections of Title 75 (Vehicle Code in this pamphlet) pertaining to pedalcycles Section 3112”

Detectors are made that work for bicycles, at little or no additional cost. Federal design guidelines exist for these detectors. If you put enough pressure on your local and state government, bicyclists can avoid the crashes and the city can avoid the lawsuits which may follow.

Here is Section 3112. Traffic-control signals:

(c) Inoperable or malfunctioning signal.—If a traffic-control signal is out of operation or is not functioning properly, vehicular traffic facing a:
(1) Green or yellow signal may proceed with caution as indicated in subsection (a)(1) and (2).
(2) Red or completely unlighted signal shall stop in the same manner as at a stop sign, and the right to proceed shall be subject to the rules applicable after making a stop at a stop sign as provided in section 3323 (relating to stop signs and yield signs).

Comment: Standard traffic signals sometimes do not detect bicycles. You may be unable to pass through a signalized intersection because the green signal is never received. When faced with this problem, you may treat the signal as malfunctioning and take the following steps to safely proceed through the intersection. First, determine that the signal will not detect you. Try to position the bicycle directly over the saw cuts in the pavement behind the white painted “stop bar” at the head of the lane. These cuts, which often take the shape of an elongated hexagon, contain the loop wires that detect vehicles. If no cuts are evident, you may have to guess their location. Wait for a complete cycle of the signal through all legs of the intersection.
If you still believe that the signal will not detect you, treat the red signal as a stop sign and proceed through the intersection only after yielding the right-of-way to all intersecting traffic (including pedestrians) that may be close enough to constitute a hazard during the time when you are moving across or within the intersection or junction of roadways.

Pennsylvania Bicycle Driver’s Manual (Street Smarts adaptation)

in answer to your question: Nope.

For what it’s worth: i believe AZBSS is exactly correct.

the question for your traffic engineer is: what does he think a automobile or motorcycle driver at a demand light that won’t change should do?
put it in park (or put down the kickstand) and go push the ped button? wait indefinitely?

Ha! I didn’t think so.

p.s. i think mionsky’s “3 minutes” is comically long. I was thinking about this the other day as one car after another –easily a dozen; not one of them stopped — was streaming through a right-on-red at 10 – 25mph at a freeway ramp… they weren’t even pretending to stop.

I will try to check the annotated statutes for that, could be something interesting.

I checked “traffic laws annotated, 1979” and the PedBikeLaws “Resource
Guide”, but couldn’t find that section is in UVC at all! I remember
that Mionske wrote that it was illegal in every state.

I checked ADOT crash data [0]. (Since that seems more promising than
anything else I have access to, and also the police have a reputation
for not enforcing rules against cyclists, except in the event of a
crash).

SOME, but not all, ACR have a field with
TCD_INOPERATIVE_MISSING_OR_OBSCURED, but it seems that’s an
intermediate thing that may have existed in 2010 but not in 2009 or
2011? For example, that is in field#18 “contributing circumstances”,
checkbox#10 (subfield “road”) in phoenix#2010-00400550.

There are several intriguing crash reports, but none are accessible on
the phoenix TAR site.

u.eRoadCondition1 IN (‘TCD_INOPERATIVE_MISSING_OR_OBSCURED’,
‘NON_HIGHWAY_WORK’, ‘OTHER_97′)

In the process I came up with a bicyclist charged with a ped statute
(28-646A2): phx#10001611367, adot#2553949. Ed: that may partially
explain the Phoenix PD claim/interpretation that “bicyclist shall not
ride in crosswalk”.

“If you ever have a crash or get a traffic ticket because a traffic
light won’t turn green, it’s the fault of whoever installed the
detector”

I think that’s an unfortunately optimistic misrepresentation of
reality: the statute says “may proceed with caution only when it is
safe to do so”. Any PD and most judges will agree that a crash is
compelling evidence that it was not safe. So I think it’s almost for
sure that a bicyclist will lose in a traffic court trial (and that
assumes they’re not so seriously injured that they can’t challenge
it). Being found responsible for the traffic ticket may influence a
later lawsuit (but see ARS 28-1599). *If* the cyclist challenges the
PD report, hires a lawyer, sues the jurisdiction, and then appeals a
couple times, then there’s reasonable chance they can win..

If you’re unable to justify the current language, and feel compelled
to change it, you could consider recommending to make a right turn, a
U turn, and a 2nd right turn… (But I acknowledge that level of
disservice is only a small step from the marginalizing advice to
“dismount and cross as a pedestrian”).

The “Words and Phrases” book has this case:

Fla. App. 3 Dist. 1992.  Traffic light at intersection that showed
steady green and yellow light was “malfunctioing,” not “inoperative,”
and, therefor, it was not contributory negligence for motorist to enter
intersection without stopping.  West’s F.S.A. 316.123(2), 316.1235,
316,1235(1).  City of Miami v. Burley, 596 So. 2d 1133.

That was, I believe, a case appealed from superior court to the state’s
appeals court, involving the city’s attempt to recover damages when a
citizen’s vehicle facing conflicting signal indicators crashed into a
city vehicle, decided against the city.

I will photocopy the case at a later date, but it specifically
distinguishes between “inoperative” meaning “not functioning at all” and
“malfunctioning”, meaning working imperfectly or only partially.

It seems that failure to detect a bicyclist/motorcyclist is an
“imperfection” and not an “inoperability”, as contemplated by that
statute, as interpreted by the FL court.

Violation of a statute enacted for the public safety is negligence per se

Sisk v. Ball, 91 Ariz. 239, 371 P.2d 594 (1962):

“Violation of a statute enacted for the public safety is negligence per se,Anderson v. Morgan, 73 Ariz. 344, 241 P.2d 786 (1952), and when this theory is supported by the evidence, [a party] is entitled to have a properly worded instruction on this issue read to the jury. Of course, a violation of the statutory duty must be also a proximate cause of the injury to constitute actionable negligence. Caldwell v. Tremper, 90 Ariz. 241, 367 P.2d 266 (1961).” 91 Ariz. at 242, 371 P.2d at 595-96.

 Here are a couple of definitions of negligence per se: nolo.comlexisnexis.com
This 2013 CA appeals court ruling involving a wrong-way sidewalk rider has a lot of references to “negligence per se”  Spriesterbach v. Holland
