Civil Litigators Standing For Justice in California

Who is liable for e-scooter accidents in San Francisco?

On Behalf of | Oct 30, 2025 | Moped Accidents

E-scooters have become a common sight across San Francisco. They offer quick, affordable transportation but also raise legal questions when accidents occur. Determining who is responsible depends on who was involved, how the crash happened and whether a service agreement affects liability.

Who may be held responsible

Liability for e-scooter crashes may fall on different parties, including:

  • Riders: Those who ignore traffic laws, ride while impaired or injure pedestrians may face personal responsibility for the accident.
  • Rental platform: E-scooter operators can share fault when poor maintenance, broken parts or missing safety information lead to injuries.
  • Other drivers: Motorists may be liable if they cause a crash by driving distracted, speeding or failing to yield. Under California law, e-scooters have the same road rights as bicycles.
  • Manufacturer: Companies that design or build scooters may be responsible for crashes linked to defective designs or unsafe components.
  • Property owner: Private property owners can also be accountable if unsafe conditions on their property contribute to an e-scooter accident.

California follows a pure comparative negligence rule. This means injured riders can recover damages even if they share some blame. The court reduces compensation based on each person’s share of fault.

Understanding each party’s share of fault helps determine who pays for the damages.

How e-scooter companies operate in San Francisco

The San Francisco Municipal Transportation Agency (SFMTA) manages e-scooter programs through city permits. Lime and Spin currently hold two-year permits to run scooters in approved areas. Riders can find and unlock them easily using mobile apps.

Rental companies must follow city rules. They must carry liability insurance, share trip data with SFMTA and use systems that detect sidewalk riding and slow the scooter automatically. SFMTA checks compliance through field inspections, ticket reviews and public complaints.

What many riders agree to

Before unlocking a scooter, riders must accept the company’s terms and conditions. These long documents often go unread, but they include important terms, such as:

  • Liability waivers: Riders release the company from responsibility for injuries or property damage, even when a malfunction occurs.
  • Shortened claim periods: Some agreements reduce the time limit for filing claims from three years to one.
  • Extended coverage: Waivers often protect parent companies, manufacturers and the city itself.

Courts generally uphold these waivers, but they do not protect companies from gross negligence, like releasing scooters with known brake problems. They also do not protect from willful misconduct. Proving either claim, however, requires a much higher legal standard for injured riders.

What is your next step

E-scooter accidents often involve more than one factor. This could include traffic laws, product defects or service agreements.

After a crash, it can be useful to note what happened, get medical care and keep records related to the incident. A legal professional can explain possible options for recovery and help you understand what may come next.
