Motorized scooter intersections and found three different types of risky behaviors including stopping beyond the stop line, riding in motor lanes, and riding against traffic. The same study found that those riding e-scooters are more likely to engage in risky behaviors. In specific, e-scooter riders were more likely to ride in motor lanes and ride against the flow of traffic though there is high variability in the types of accidents that occur and can vary based on time of day. Understanding the health impacts of electric scooters should be considered when developing standards and policies for these new but prevalent modes of
