Bicycle Passing Clearance Sign (R4-19)

R4-19

The Bicycle Bicycle Passing Clearance Sign (R4-19) was added to the latest edition of the MUTCD, the 11th edition Dec 2023 (here’s the bicycle chapter: part 9 .pdf). The sign is not presently in in Arizona’s MOAS (Manual of Approved Signs). — I’m not sure what’s up with that since Arizona state law does have a specific minimum passing law as required by the standard in order to use the sign.

Here is some background on how the Passing Clearance sign was developed on its way to be added to the MUTCD. Continue reading “Bicycle Passing Clearance Sign (R4-19)”

Scottsdale councilman defends roundabout cancellation

As a follow up to:

What’s going on with Scottsdale?

The cancelled roundabout is in the news again, and I’m wondering if anyone can explain things other than in politically partisan terms? In other words, if it’s true there was “massive pushback” for the project, why is that the case? A roundabout is likely to be safer overall (reduces peak thru speed) while being more “efficient” in terms of traffic flow. In other other words, “Graham said the completed intersection improvements will result in a safer corridor than what existed before.” can be true, and at the same time the (cheaper) roundabout could be even safer, and at a lower cost.

Scottsdale councilman defends roundabout cancellation
Updated safety project is now reporting a $3.4 million increase

Published: Mar. 12, 2026 at 7:01 PM MST|Updated: 18 hours ago
SCOTTSDALE (AZFamily) — Scottsdale City Councilman Barry Graham is defending his vote to cancel a planned roundabout project along the Scottsdale Road corridor, after a report released this week showed the replacement project will cost an additional $3.4 million.

“It would have been the only roundabout on the north Scottsdale, Pima corridors north of the 101. It was out of character and got massive push back from local residents,” said Graham.

The project targets a two-mile stretch of Scottsdale Road in the northern part of the city, with the goal of improving safety and drainage.

The previous city council had approved a roundabout at the Dynamite Road intersection as part of this broader safety improvement plan. The total project budget was capped at $43.7 million, with a federal grant covering $31 million of that amount.

In April 2025, Graham and three other council members voted to cancel the roundabout portion of the project and pursue a different design. Graham said the roundabout was not the right fit for the busy corridor.

“We protected Scottsdale Road from a permanent roundabout amid passive pushback from our residents — we stood with our residents,” Graham said.

When the city canceled the roundabout, it also forfeited the $31 million federal grant tied to the project. Graham said the Maricopa Association of Governments stepped in and provided Scottsdale with roughly $30 million as a funding swap for the federal grant, meaning the city is not responsible for the full cost increase.

The report released this week shows the project’s cost of $3.4 million, this funding will be covered by the projects contingency fund and not at an extra cost to tax payers. The city now has only $850,000 remaining in this project’s contingency fund to cover any additional unexpected cost increases.

When asked whether further cost overruns could put the city in a difficult financial position, Graham acknowledged the possibility.

“It’s possible. Every time we do a project, overruns are possible for every project, which is why we hire experts who watch this carefully,” Graham said.

Graham said the completed intersection improvements will result in a safer corridor than what existed before.

“This intersection after these improvements are done will be much safer than it previously was,” he said.

I also am not sure about how accounting works, but the way I read it, despite Scottdale’s decision costing a $31 million dollar federal grant, it isn’t out the money because MAG covered it to the tune of $30 MILLION DOLLARS — which I would imagine means that money isn’t available for some other safety project somewhere else in the Maricopa region.

More about more about ebike crash reporting

I was invited to attend a meeting 2/23/2026 pulled together by Kerry Wilcoxson (ADOT State Safety Engineer) where he invited folks from Arizona DHS (Dept of Health Services) as well as some other interested parties.

The topic being e-bikes and crash reporting. Which is of course getting all sorts of (mostly negative) attention, for understandable reasons. But the truth is we have very little data to go on… Continue reading “More about more about ebike crash reporting”

Driver kills triathlete on Central in Phoenix

2026-02-08 Southbound Central near Elwood. Police say a the driver of a van veered to the right crossing into the separated bike lane, killing a bicyclist and continued up the curb and on to sidewalk. The driver fled the scene. Police say he admitted using fentanyl and continued on his way to purchase some more. Continue reading “Driver kills triathlete on Central in Phoenix”

More about e-bike crash reporting; and What’s going on in Maricopa?

(referring to the City of Maricopa. Which confusingly is split across Maricopa an Pinal Counties).

2026-02-03 ~ 8am Juvenile avoids serious injury after being struck on busy Porter Road:

Maricopa police responded to a vehicle-versus-pedestrian collision involving a juvenile riding an electric bike on Porter Road on Tuesday morning. The incident occurred at approximately 8 a.m. near the intersection of Porter Road and Alan Steven Parkway, according to the Maricopa Police Department. This intersection is near both Sequoia Pathway and Leading Edge Charter schools…
Police said the child was riding the electric bike against the flow of traffic when they attempted to cross the roadway and were struck by a vehicle making a right turn at low speed.
The juvenile sustained minor bumps and scrapes. A parent declined medical transport at the scene, police said…
No citations were issued in this morning’s incident.

This is a reminder to check crash records, and wonder if it was actually an electric bicycle as defined (e.g. a class 1, 2, 3) or rather a motorcycle with an electric motor (like the popular Surron, Talaria, etc), that are effectively illegal. There’s a lot of sloppy language floating around. It’s not completely clear if police will file a crash report as it may be below the reporting threshold, so we’ll just have to wait and see.

Bystanders hurt/killed in high-speed chase I-10 Tucson

2026-01-27 12:30a. Ug. A pedestrian was injured and a bicyclist was killed as  a result of a driver, who was fleeing police at the time, crashing into them.

I assume, or hope, the DPS will be doing a thorough evaluation of the events vs. their protocols — the tragic outcome where un-involved people get hurt/killed a collateral damage during chases is exactly why police probably shouldn’t be doing high-speed chases in the first place. (Radios are MUCH faster than vehicles).  The chase began at MP252 on I-10 which is a several miles away from the Speedway exit where the chase ended, and the driver was shot by police.

Another white Tesla hit-and-run, this one in Tempe on Baseline

By another, I mean just a few months ago back in October 2025 a hit-and-run driver of a “speeding” white tesla killed Will Castañeda in a marked crosswalk back in October of 2022 in Phoenix. No news. Did police ever find the driver? Oh well, what are you going to do? Tesla’s have instrumentation and telemetry up the wazoo.

So anyway, according to this lawyer-blog (not in the news, by the way, where do they get it? Citizen app? Don’t Tempe police consider this to be BOLO-worthy?). The incident described, hit-and-run w/injury,  is a felony crime.

A pedestrian suffered injuries after a traffic crash involving a vehicle on January 24 … The incident occurred around 8:19 p.m., near West Guadalupe Road and South Kyrene Road… According to initial information, a white Tesla struck the pedestrian and then left the area. Witnesses reported that the vehicle traveled west toward Colonial Place following the crash.

Emergency responders arrived and found the pedestrian conscious but injured. The person complained of back and wrist pain and showed visible bleeding…

 

Glendale passes ebike ordinance

Ug. So many words in this new ordinance O25-50. Read the whole thing here.

It makes bike lane use mandatory for ebicyclists, with exceptions; assuming the exceptions are well thought out — and I’m not sure they are — this isn’t necessarily a problem. But most troublesome is adding an impeding rule: Continue reading “Glendale passes ebike ordinance”

Proposed legislation would regulate bicycle speed

The spring 2026 legislative season (57th, 2nd Regular)  is apparently up-and-running already! Senator John Kavanaugh (R-Scottsdale) has proposed legislation that would limit a bicyclist’s speed in certain places.

SB1008 bicycles; mobility devices; speed limits

There was a veritable media blitz; here are a few: Continue reading “Proposed legislation would regulate bicycle speed”

Bicyclist killed at Tucson HAWK crosswalk

11/16/2025 A bicyclist was killed when a driver ran a red light at an “activated” HAWK crossing at East Speedway Boulevard and North Richey Boulevard.

This is the only fatality I am aware of that has ever occurred at an activated HAWK crossing.

Police have already signaled there will be no serious charges (“The driver of the vehicle remained at the scene…” and “determined she was not impaired”. At the completion of TPDs investigation, it will probably be forwarded to the county attorney, who will decline charges, because that’s what they do when someone is killed by a not impaired driver. That will bring it back to the city attorney for consideration of misdemeanor (or civil charges, like just a traffic ticket). Continue reading “Bicyclist killed at Tucson HAWK crosswalk”

An un-named on duty Phoenix Police officer was indicted by grand jury on charges of aggravated assault and endangerment. The ag assault is theoretically a serious felony, but it would be unsurprising, if convicted, the sentence would be just probation [1].

Driver of Speeding White Tesla hits and kills bicyclist in Phoenix before fleeing the scene

{UPDATE: news now (published Wed Oct 22) says Osborne near Piestewa in a marked crosswalk. Which would be probably at the canal/trail crossing, which appears to have a HAWK signal]

Today is Tuesday. In an important update to  the hit and run killing Sunday afternoon (in addition to a motorcylist seriously injured in separate hit-and-run!) — how are we just now learning that the “white car” is a white Tesla. That’s a lot more specific don’t you think?

2025-10-19 ~ 3pm Osborne Rd near Piestawa Fwy bicyclist Will Castañeda killed in a marked crosswalk by a hit-and-run driver of a white Tesla. Osborne Rd runs underneath the freeway, there is no freeway access here. There are marked crosswalks both immediately east and west of the underpass, the Grand Canal Path is on the the west side and has a HAWK signal, the crosswalk on the east side is uncontrolled.

In any event BOLO white tesla w/ front damage. Here is the article published yesterday: Continue reading “Driver of Speeding White Tesla hits and kills bicyclist in Phoenix before fleeing the scene”
