Today is bike2work day. Most folks are not aware that my agency #NTSB cares A LOT about vulnerable road users, like bicyclists. Here is an example that I am very proud to contribute to. ntsb.gov/news/events/Pa…
Sammy Cohen Eckstein should be with us today. I'm encouraged to see @GovKathyHochul signed Sammy’s Law into law last week, which will help prevent crashes and save lives. We still have so much more work to address the national crisis of roadway fatalities.
We saw this flying over the Alps.
More #SS4A funding announced by @USDOT for year 2 planning and demonstration projects today: transportation.gov/sites/dot.gov/… lots of small town and rural region safety work ahead. Hope all this work leads to zero road deaths and serious injuries. #visionzero #safesystem #safetyculture
#NTSB Member Chapman highlighted the needs to improve Pipeline Leak Detection and Mitigation at the 2023 AGA Executive Safety Summit.
SAVE THE DATE! We encourage small and midsized #aviation operators to attend our upcoming #NTSB #webinar on May 11 to learn how an SMS can prevent accidents AND be scaled to fit ANY sized operation! Register now: conta.cc/3o6q1m3 #bizav
Best thing I heard so far this morning in this pedbike panel discussion - #EMPATHY - all drivers are pedestrians and the system needs to stop victim blaming. #kansasdot #safesystem #VisionZero #transportationsafety
What did the pedestrians do illegally and what did they wear reflective clothing? Take a guess where these questions come from? We still have a very long long long way to go to be a walk friendly country! #pedbike #pedsafety #safesystem #visionzero

In the resort town of Les 2 Alpes, in the northern French Alps there is a bike race which starts at a 3,400m-high glacier. 1/2
I cannot agree more! Why do we allow non-emergency vehicles to traverse thru under streets at that speed?

I made the same act same observation the 2 posts next to each other 😱🤷♂️😂
EAA #AirVenture2022 is an event unlike any other. It was great visiting with aviators & aviation enthusiasts from around the world about improving general aviation safety. I also had the privilege of joining exemplary aviators on a panel to promote pilot professionalism. #OSH22
Alcohol-detection systems could prevent more than a fourth of U.S. road fatalities. #safesystemapproach iihs.org/news/detail/al…
Speeding is a troubling trend that prevents #RoadwaySafety. @FamilyNsc discusses @NHTSAgov's new ad campaign that addresses speeding while encouraging drivers to slow down and be more careful because “speeding wrecks lives”. Learn more: bit.ly/NHTSASpeed.
