A 69-year-old woman was severely injured Monday afternoon when she collided with a cement mixer while riding an e-scooter near the intersection of Bay Street and the Embarcadero.

The incident happened at 3:25 p.m. on Monday, and as the Chronicle reports, the woman was traveling through the intersection when she hit the cement mixer. She reportedly suffered life-threatening injuries and is now hospitalized in critical condition.

Just last week, a new report from a prominent medical association referred to e-scooters as a new "urban health scare," and found that injuries related to the scooters more than tripled nationwide between 2014 and 2018. Hospital admissions from scooter injuries doubled between 2017 and 2018 alone.

About a third of the injuries involved the head, and the report found that the rate of head injuries relative to all other injuries was more than double the average rate for cyclists.

The most commonly injured demographic, per the reports, were 18- to 34-year-olds, making the elderly woman's case on Monday an outlier.

It's not clear if she was wearing a helmet at the time of the crash, or what the exact circumstances of the collision were.
