Which insurance applies when a rideshare vehicle is in a crash depends on what the driver's app was doing at that moment - the three periods state transportation network company laws define, and the gap that personal policies leave.
Almost every state has a transportation network company statute that sets insurance rules for drivers using platforms such as Uber and Lyft, and those rules turn on the state of the driver's app. When the app is off, the driver is a private motorist and their personal policy applies. When the app is on but no ride has been accepted, the company must provide liability coverage at a level the statute sets, usually on a contingent basis that applies only if the driver's own policy does not. From the moment a ride is accepted until the passenger is dropped off, the company's policy is primary and at a substantially higher level, and typically includes uninsured and underinsured motorist coverage for the driver and passengers.
The gap the statutes were written to close is that personal auto policies commonly exclude driving for hire, so before these laws a driver logged in and waiting for a fare could be uninsured altogether. Some personal insurers now sell rideshare endorsements that fill the waiting period; whether a driver has one, and whether the app was on, are among the first facts an insurer establishes after a crash. Passengers and other road users injured during a ride generally look to the company's primary policy; a driver's own injuries during a ride depend on the state statute and on coverages the driver chose.
Drivers are usually independent contractors under the platform agreement, which is why claims are brought against the insurance layers rather than against the company as an employer; a small number of states have treated drivers differently for particular purposes. Delivery platforms are covered by some of the same statutes and not by others.
A passenger or another driver injured by a rideshare vehicle should get the driver's name, the platform, and the trip details from the app before leaving the scene, because which of three insurance layers applies is decided by timestamps the company holds. A rideshare driver hurt while working should ask a lawyer which period they were in, whether their personal policy excludes the loss, and whether the company's uninsured-motorist coverage reaches their own injuries in their state.
