Tempe’s Local Ordinance


Background is two events; one was the death of Xiaoying Wen who was killed in a crosswalk in Nov 2017 proceeding with a walk signal; after being struck by a driver who made what would normally be considered a “bad left”. Tempe Police stated that due to local law, the bicyclist was at fault. Many people, including me, think of that as being a wrong, or wrongful determination — whether it be a wrong interpretation or a bad ordinance.

Scottsdale (and now Tempe) regulates scooter/bike sharing companies


I can’t possibly keep up with all this… but just to point out, these regulations affect the companies; and have nothing to do with operation and rules of the road. The latest being Scottsdale:

Renting a bicycle or scooter in Old Town Scottsdale? Here are the new rules to know

In one oblique reference to rules-of-the-road,  it mentions/claims “Renters can ride … scooters on sidewalks”; I don’t have time to unpack yet another set of local ordinances but I don’t see how that’s possible ; see e.g. here for Phoenix and Tempe operating ordinances.

Bicycle Friendly Delaware Act

The state of Delaware passed a package of updates to rules-of-the-road in 2017; as outlined by bikelaw.com

In October 2017, Delaware’s governor signed the Bicycle Friendly Delaware Act, placing into state law some cutting-edge, pro-bike reforms that put Delaware emphatically into a category of one among U.S. states when it comes to favorable statutory law treatment of cycling. The highlights:
1. requirement that drivers have to change lanes to pass;
2. the “Delaware Yield” at stop signs;
3. deletion of the “as far to the right as practicable” provision;
4. no aggressive honking at cyclists.

What is an e-scooter?

Xiaomi Mi Electric Scooter

Just what is an e-scooter?  … what rules of the road apply?

For our purposes here, an e-scooter is an electric powered “kick” scooter that is sized to accommodate up to most adults; with weight limits being typically 220lbs. They travel on level ground up to about 15mph. A very popular model, the Xiaomi which is no longer sold at retail is said to be typical, and the basis for most of the scooter sharing companies, a la Bird, Lime, etc.

This article IS specifically trying to get to the bottom of what definitions and requirements may or may not apply. It IS NOT intended to delve into traffic safety; nor the relative merits of dockless sharing systems

Motorized bicycles, Ebikes and crash reporting

Executive Summary

  • People riding motorized bicycles are categorized as DRIVERS, and not as bicyclists, for crash reporting purposes.
  • How will Ebike crashes be reported?
  • new wildcard: what about escooter crashes?

Each of these has the potential to skew crash reporting statistics. Motorized bicycles have not seen wide use, but ebikes are expected to become much more common

I propose adding a few new “Body Style” definitions: 1) bicycle (well, pedalcycle), 2) motorized bicycle, 3) ebike; this would not require any changes to the Arizona Crash Forms, simply an update to the Crash Form Instruction Manual.

It is expected that ebikes will see large growth in use in the coming years; e.g, the WSJ reported:

E-bikes represent the fastest growing slice of the U.S. bicycle market today. sales totaled $135 million for the 12 months ended in October and are up more than eight full since 2014, according to market research firm NPD group Inc. still, e-bikes account for just 4% of the $3.5 billion dollar overall US market. — WSJ January 7, 2019

it is also feared that this will have a deleterious impact on (e)cyclist safety since it’s possible that ebikes will generally be used at higher speeds potentially by less-experienced users, and also possible growth in older riders who tend to be more vulnerable to injury when a crash occurs. Feared but largely unknown at this time. [for some parallels, see recently reported large increases in older ebike rider fatalities in NL, or this research from 2015 Germany noting similar trends. Ebike penetration is notably higher/faster in Europe compared to US] Continue reading Motorized bicycles, Ebikes and crash reporting

Ebike bill rides again

[Update — It’s all passed and signed as of 5/16/2018… see below, the bill was initially VETOED it in an unrelated  political tiff]

Late in this legislative season (53 2nd regular), an ebike bill has once again surfaced from Rep Worsley; this time as a “striker” in the former dark sky lighting special plates bill HB2266.

The bill is suddenly, as is always the case I guess with strikers, being heard, scheduled for 3/20/2018 in the senate where it passed unanimously… Continue reading Ebike bill rides again

Left Cross Collision

Left-Cross collision. Graphic: cyclingsavvy.org

A Cross-type Bike-MV collision occurs when a bicyclist and motorist who are traveling in opposing directions collide while the motorist is making a turn. If both are traveling in proper direction, it would be a left cross; as illustrated between the blue vehicle and the bicyclist in the illustration. For a counter-flow bicyclist, a right-cross can occur.

(This in in contrast to to a hook collision, which involves a turning motorist and a same direction cyclist. ) Continue reading Left Cross Collision

Arizona Electric Bicycle Legislation (bill died)

An ebike bill PASSED in 2018: HB2652. Below info is for historical purposes…

[5/10/2017; bill stalled. Never got a House floor vote]
[Current Status as of 3/1/2017: passed the Senate by wide margins, also passed House T&I Committee but they implied it would need to be amended to pass the floor; as of 3/19 it’s not passed the house; see below ]
ca-e-bike-croppedAs of spring 2017 there is an e-bike bill working its way through the legislature.  SB1273  (2017, 53rd/1st Regular session). This bill, if passed, would address some or all of the confusion documented at length in these pages, at least for e-bikes. The bill’s prime sponsor is Bob Worsley (R-Mesa), is senate president so I’d have to assume it’s going to pass ; [correction, Yarborough is, so I have no idea how i got that wrong] and is moving fast, as of the time of this writing (early February 2017) it has already passed the Senate Transportation and Technology Committee unanimously with little debate. Besides being senate president,  Worsley is the chairperson of the senate Transp committee. I have no idea about the house but there’s little apparently standing in the bill’s way.  Continue reading Arizona Electric Bicycle Legislation (bill died)
