A mobility collision is an accident involving a personal mobility device (PMD). These devices are small, electrically powered, and designed to carry one person over short distances, including e-scooters, e-bikes, and electric skateboards. A collision can happen with a pedestrian, a motor vehicle like a car or truck, or a stationary object as these newer forms of transportation share space with established traffic.
Contributing Factors to Collisions
The reasons behind mobility collisions stem from a combination of human behavior, environmental conditions, and device characteristics. Operator behavior is a primary factor. For PMD users, this can include a lack of experience, failure to adhere to traffic laws, or distraction. For motorists, common issues include not noticing the smaller profile of a PMD, incorrectly estimating its speed, or being distracted.
Infrastructure plays a substantial role in these incidents. Many urban environments were not designed with micromobility in mind, forcing PMD users into spaces with faster cars or unpredictable pedestrians. Poorly maintained sidewalks, potholes, and complicated intersections without clear guidance for PMDs can directly lead to loss of control or conflict.
The nature of the devices also contributes to risk. While less common, mechanical failures like sudden brake or motor malfunctions can occur. A more frequent issue is the quiet operation of electric motors. This means pedestrians and drivers may not hear an e-scooter or e-bike approaching, removing a layer of awareness that often prevents accidents.
Vulnerabilities and Common Injuries
Riders of personal mobility devices are classified as “vulnerable road users” because they lack the protective features of passenger vehicles. A PMD rider is not enclosed in a steel frame and has no access to airbags or seatbelts. This direct exposure means the rider’s body absorbs the entirety of the impact force, leading to a higher probability of serious injury.
This vulnerability is reflected in the types of injuries commonly sustained. Head injuries are among the most frequent and serious, ranging from concussions to traumatic brain injuries (TBIs). Fractures are also common, particularly to wrists, arms, and ankles as riders try to break their fall. Severe abrasions, often called “road rash,” and deep lacerations are also prevalent outcomes.
The severity of these injuries makes personal protective equipment important. While wearing a helmet does not prevent an accident, it is a determining factor in mitigating head trauma. The difference in outcome between a rider who hits their head with a helmet and one without can be life-altering.
Navigating Shared Spaces Safely
Creating a safer environment requires a conscious effort from everyone using roads and sidewalks. Mobility device riders, motorists, and pedestrians each have a role in preventing collisions. A shared sense of responsibility is fundamental to ensuring predictable interactions in these crowded spaces.
For those riding mobility devices, proactive safety is important. This begins with wearing a helmet on every ride and using lights and reflective gear at night to maximize visibility. Riders must also act as predictable road users by obeying traffic signals, riding at a safe speed, and yielding to pedestrians.
Motorists must adapt their driving to account for these smaller vehicles. This means providing PMD riders with at least three feet of space when passing and being especially vigilant when turning or changing lanes. Double-checking blind spots is important, as the slender profile of an e-scooter can be easily missed.
Pedestrians also have a part to play in safety. Being aware of your surroundings is the first line of defense, which includes avoiding noise-canceling headphones in high-traffic areas. Before crossing a bike lane or multi-use path, look both ways, just as you would when crossing a street.
Post-Collision Protocol
In the moments following a mobility collision, a clear set of actions can protect your health and document the incident for any future needs.
- Prevent further harm by moving yourself and your device out of the flow of traffic to a safe location, such as a nearby sidewalk, if you are able.
- Seek medical attention without delay. Adrenaline can mask pain, and serious injuries like concussions may not have immediate symptoms, so calling for emergency services is a prudent step.
- Contact the police to report the collision. A police report serves as an official record of the incident, capturing details that are indispensable for insurance or legal proceedings.
- Document everything at the scene if you are physically able. Use your phone to take pictures of the location, damage to your device and other vehicles, and any visible injuries.
- Exchange essential information with any other individuals involved. This includes their full name, contact information, and insurance details, as well as contact information from any witnesses.
