Electric Scooter Accident Statistics

From 40.6 million e-scooter rides in 2022 to rising emergency visits after 2017 to 2019, the page pinpoints what injuries actually look like, including alcohol involvement around 1 in 4 patients and head and face injuries in 62% of European hospital cases. It also shows why helmets matter, with head injury severity dropping to an odds ratio of 0.33 even though helmet non use is reported in more than 80% of riders across studies.

Electric scooter crashes are showing up in emergency care with a steady pattern, but the details are what really stand out. For example, alcohol involvement has been reported at about 25% of e-scooter ED patients, while helmet use in one study was a median 33% and helmet non-use was reported in more than 80% across included studies. Let’s look at how injury type, road conditions, speed, and rider behavior connect to the risk numbers, and what that means for prevention.
