Currently visiting family in Florida and it was surprising and a bit worrying to go on a run and find that there are now big bollards blocking golf carts from using a shared use path that goes over an interstate Not sure if a crash happened or what, but they've decided to cut off a vital link

NHTSA released estimates of traffic fatalities in the first half of 2025, so I made a quick visual to show that bicyclists are one of only two categories with increasing fatalities Data: crashstats.nhtsa.dot.gov/Api/Public/V... Visual: www.datawrapper.de/_/EFpSk/

When people ride on the sidewalk it's because it feels more appropriate than the alternatives available. Engineering solutions are always more effective than regulatory.

Reminder for anyone who needs it that there is a roadmap for updates to the New Car Assessment Program www.nhtsa.gov/sites/nhtsa.... It was published in late 2024 to comply with 49 USC 32310 It's likely that the Trump administration will not follow this roadmap, but it'd be nice if they did

Great thread and blog by @nacto.bsky.social about state adoption of the MUTCD! "For a document that emphasizes uniformity and rigidity, there is inconsistency and a lack of transparency in the states’ updates to the MUTCD" Congress now requires more frequent updates, so these features matter more

Is it just an intractable issue with pedestrian safety campaigns that no matter how much people correctly identify drivers as the reason that pedestrians are unsafe, the campaigns can't just focus on that? www.mass.gov/news/massdot...

Great partnership by Lime and @bikeleague.org showing how bicycle infrastructure gets more people riding and reduces incidents Baltimore, Nashville, and Phoenix are all Bronze Bicycle Friendly Communities, showing that these effects are not just in the best cities for biking, but in any city

The @bikeleague.org supports the "Stay In Your Lane" Act because it requires manufacturers to produce information and safety assurances for Operational Design Domains, meaning operating conditions where their system is designed to function safely based on the presence/absence of certain road users

We all pay for crashes NHTSA says that 22% of adults aged 19–64 with hospital-admitted crash injuries became Medicaid-eligible 35% of those who converted to Medicaid stay on Medicaid indefinitely with lifetime Medicaid costs of $316,000 (2019 estimate) crashstats.nhtsa.dot.gov/Api/Public/V...

Noice.

"'I turned around and saw her slumped over. It will forever be a picture that is burned into my head.' Miles' car was struck head-on by a speeding drunk driver in 2023. Her 6-year-old daughter was killed in the crash." There's so much more we can do to prevent these tragedies

Very cool to see Luka Doncic gift e-bikes to players and staff E-bikes are great Unfortunately, I have to be a buzzkill and note that the "e-bikes" he chose appear to not be legally e-bikes in the state of California The "e-bikes" he chose have power and speeds in excess of the 3-class system /x

"the 'intoxication detection' system, which uses Maisart AI to detect drunk drivers...would provide 'driver alerts and vehicle-control interventions, as needed, to help prevent alcohol-related accidents.'" I'd be interested in trying this on a closed track www.carscoops.com/2025/12/your...

An astonishing percentage of Americans are open to car-free living. The problem isn't attitudes. The problem is the failure to invest in viable options. humantransit.org/2025/12/many...

When NHTSA last had a big initiative to end distracted driving this was a featured cell phone www.nhtsa.gov/sites/nhtsa.... They haven't updated their first proposed VOLUNTARY guidelines in over a decade www.regulations.gov/document/NHT... Definitely not "safety first"

"most Americans want stronger safeguards that prevent impaired driving... 67% support requiring all new cars to include alcohol-impairment prevention technology" Congress called for NHTSA to implement impairment prevention technology in the last transportation bill newsroom.aaa.com/2025/12/driv...

"we are prioritising mobility-focused use cases such as traffic flow analytics, pedestrian and cyclist safety" -interesting "The system combines wind and solar generation with energy storage and a grid connection" -lost me Not sure what it is, hope it helps though cities-today.com/north-texas-...

"Japanese roads don't permit high speeds, defaulting to just 24 miles per hour in urban areas and 18 mph on side streets." Visiting family in Florida and it is literally impossible to leave the neighborhood without entering a 40 mph road Kei trucks "typically top out at around 37.3 miles per hour"

"One thing I like about Chinese cars is that so many are designed to prioritise tech and extreme comfort like American cars used to" There are many reasons to dislike the US trend of giant trucks as everyday family vehicles, but also they're just terrible to drive

"Mayor Daniel Lurie announced an executive directive that formally links police enforcement with public health data and transportation engineering" Great to see this, the siloing between enforcement and engineering in American approaches to traffic safety is desperately in need of reform

NY State Senator sponsoring a Stop Super Speeders bill "said some of his colleagues seem to believe that 'drivers are entitled to special treatment and that any efforts to hold drivers accountable impinges upon that God-given American right to be free behind the wheel'” stateline.org/2025/12/16/s...

Act NOW to oppose transferring corridor ownership and state funding for the proposed Shenandoah Rail Trail to the Shenandoah Valley Battlefields Foundation, which opposes the rail trail and seeks an economically infeasible excursion rail service instead: www.shenandoahrailtrail.org/news/project...

“The parking in front of my house was removed on my side of the street, and I don't want you to give it back to me.” Great energy from a local resident! @parkingreform.org

"the agency’s in-house research team, is piloting two speed feedback signs at high-congestion points on the MBT" DDOT saw >5,000 users/day in October, and "that one out of five of those users travelled more than 15 miles per hour during that period" aashtojournal.transportation.org/ddot-starts-...

"Violence that occurs in the traffic realm is, by definition, traffic violence. A car crash is always a car crash...[if you] feel a sense of unease saying these words, it is because we have been raised in a culture that has systematically and deliberately worked to shift the blame for that violence"

"consumers will pay at least $187 more over the lifetime of the vehicle, even with the expected price savings upfront, according to an appendix to NHTSA’s proposal" Higher lifetime cost "driven by a total increase in fuel costs of $1,112 to $1,431" assuming "$3 to $3.20 per gallon through 2050"

The @bikeleague.org is proud to join the many organizations opposing this bad e-bike bill! If passed, a drivers license, registration, and insurance would be required to ride all e-bikes, including the lowest-speed e-bikes that require pedaling Please sign & share!

"the DMV told lawmakers that it could not 'complete the necessary programming' for the law [requiring in-car breathalyzers for anyone convicted of a DUI], citing possible technology delays and costs of $15 million or more" ~1,300 people killed per year by drunk drivers in CA, a much bigger cost

"As of January 2025, DOT reported that it had completed 38 priority actions [in the National Roadway Safety Strategy] and 5 were still in progress... [DOT] attributed 10 consecutive quarters of declines in traffic fatalities to the progress" www.oig.dot.gov/library-item...

TBH I expected an article about Autonomous Vehicles from WealthyDriver.com to focus more on how AVs compare to a chauffeur www.wealthydriver.com/gear-equipme...

@nyc.streetsblog.org @thewaroncars.bsky.social April Fools -not. DOT advisory panel recomnd dedicated truck tunnel from NJ to Manhat, w/1K new prkng spots for trucks. Coincidentally, chair of panel is founder/CEO of Centerpark, a NYC based parking mgmt co. www.freightwaves.com/news/dot-adv...

"The claim is that moving traffic faster will boost productivity and grow the economy.... [But] Faster speeds involve less time to react and longer stopping distances, meaning more crashes. And higher speeds mean worse crashes that take longer to clear. A fatal crash can shut a road for hours."

"Bike joy is a pure idea. It occurs spontaneously and without instruction" "the frontier of bike advocacy is everywhere and even the smallest act of bike joy pushes our lines forward" youtu.be/_Oxze3cKr9I?... Fun to bring a little Andor into a bike conference

Really cool opportunity for those with the ability to attend! From the Losingar site, it says it is critical to set a target for how many miles of road need transformation or speed calming measures That would be an incredible step for any state, city, or our federal government

While US cities, and some states, have adopted Vision Zero in name the overwhelming culture of traffic safety in the US is the traditional culture that countries have had to change to successfully move toward zero deaths We still hear "people don't want safety" and do too little to change systems

"The REPAIR Infrastructure Act would pick up where the Reconnecting Communities Pilot left off" with "over $13.8 billion in requests [that] unfortunately went unanswered" Thanks to @bluntrochester.senate.gov @merkley.senate.gov and @warnock.senate.gov for leading on this legislation

"Since launching in 2017, BusPatrol’s cameras have been mounted on more than 40,000 school buses in nearly two dozen states, and the for-profit company has gobbled up about 90% of the market share" "survey suggests that over 39 million violations occur annually" 👀 www.usatoday.com/story/news/n...

The city of LA budgets "for building only 200 ramps a year. At that rate, it would take 60 years just to cut curb ramps on the corners that don’t have them, and then another four centuries to update all the existing ramps" Oof, and there are probably a lot of cities in similar situations out there

"There's a single answer to both affordability and traffic deaths! Just make cars lighter and slower. Reducing travel speed by just 5% can prevent 30% of fatal road crashes" Yes! #SlowRoadsSaveLives

"When he’s riding, 'I deprioritize [Waymos] in terms of my level of concern. I can focus on the human drivers.'” - Executive Director of BikeLA "LA is not a fun place to bike, says Ken McLeod [me], the @bikeleague.org policy director, but biking around an autonomous vehicle felt pretty safe."

"The results found that while 58% supported a national 20mph speed limit, just 28% opposed... 13% had no particular views. [Support is] 74% among households with children under 18 years" "78% of respondents are concerned about vehicles driving too fast in their local area" #SafetyOverSpeed

"Duffy highlighted one reason the tiny cars... are problematic for the U.S. market... They're really small ... in a collision with an American SUV, they don't stand a chance" TBH this is less why small cars are a problematic and more why gigantic SUVs are problematic www.axios.com/2025/12/05/t...

Two big takeaways from this article: 1) Tariffs are hurting US bike manufacturers who assemble bikes from imported parts (reshoring, while possible, will take time) 2) Buy an e-bike with UL certified battery and electric systems to ensure good battery safety

QOTD from the CEO of a bankrupt US e-bike manufacturer: "I really thought Trump would put the tariffs higher on our competitors, and least help local manufacturers … but the tariffs didn’t help local manufacturers at all" www.washingtonpost.com/business/202...

Interesting article with good citations "laws have treated cyclists like small, slow cars" Big reform ideas: Idaho Stop Flexible sidewalk riding rules Decriminalization of technical and equipment violations (helmets are their example) I wonder how many small, slow micromobility devices fit in

I often hear that there's not a federal interest in biking and walking (because they don't often cross state lines) What's the federal interest in pull ups? Is a healthy population relevant to pull ups at airports, but not biking and walking in communities?

I took a vacation to New Zealand last month I really appreciated the low curbs of a protected bike lane when it crossed driveways in Auckland, some neat lean bars at a crosswalk in Christchurch, and a pushbutton to activate a light on a one-lane bridge outside Wanaka Nice details for better biking

There's a proposal to reform National Highway Traffic Safety Administration (NHTSA) grants Unfortunately, it focuses on making grants easier over any strategic direction NHTSA needs reform and meaningful reform means leadership, not just easier grants bikeleague.org/in-the-face-...

This was a choice, not by the person walking but by the decision makers who refuse to prioritize them. Photo Credit: D_S_J_

Excited to see this safety leadership by New Jersey Hopefully they don't also take a step back by putting in place e-bike restrictions through A6235/S4834 While the Target Zero plan calls for action on Class 3 e-bikes the proposed legislation would affect all classes dot.nj.gov/transportati...
