If you are a Lyft passenger, your spouse is absolutely allowed to ride with you. A standard Lyft vehicle can carry up to 4 passengers (and an XL can carry up to 6), and the fare is the same regardless of whether you ride alone or with your spouse. However, if you are a Lyft driver, the rules are different. In 2026, Lyft's Terms of Service strictly prohibit drivers from having any "unauthorized" people in the vehicle while they are online or giving a ride. This means a driver's spouse, child, or friend cannot ride along in the front or back seat while the driver is working. This is primarily a safety and insurance regulation; the commercial insurance provided by Lyft only covers the driver and the paying passengers. Furthermore, passengers have a right to a private experience, and having the driver's spouse in the car would be a violation of the community guidelines. Violating this rule can lead to the permanent deactivation of the driver's account in 2026.
