INSURANCE
All drivers are required to carry valid personal auto insurance, which will be your primary coverage. Every ride on the uberX platform is backed by $5,000,000 of contingent coverage for bodily injury and property damage to third parties. This means that if, in the event of an accident, your own personal insurance is exhausted or does not apply for any reason, passengers, pedestrians, other drivers, and the community at large can rest assured knowing that ridesharing partners remain covered by a robust first-class policy.
