Before you begin driving with a new passenger in your car, pay attention to any signs of whether the passenger is sick, inebriated, potentially dangerous or otherwise unsafe to transport. Once you begin driving with a passenger in your car, you then owe that passenger a duty of care to keep them safe on the road. This is worth mentioning because many passengers use Uber or Lyft rides as a substitute for calling 911 to seek medical treatment.
Ever since California Assembly Bill 5 (AB5) went into effect on January 1, 2020, Uber and Lyft drivers are considered employees of the companies that they are driving for. This means that the companies assume liability for any of their drivers' failure to exercise their duty of care when transporting a sick passenger. While it is true that Uber and Lyft drivers are not trained medical professionals, they still assume liability for the safety of the passenger if they allow someone who needs medical attention to stay in their vehicle.
Upon noticing that a passenger may be in need of urgent medical attention, an Uber or Lyft driver should attempt to communicate with the passenger to assess the severity of the situation. Do not hesitate to call 911 and report any medical emergency. You have every right to pull over your vehicle if it appears that the motion of driving is making the passenger nauseous.
