Car share is a membership service where you rent a car by the hour or day instead of owning one
You pay a monthly or annual membership fee, then reserve a vehicle through an app, drive it for as long as you need, and return it to a designated parking spot. The service covers gas, insurance, and maintenance — you pay only for the time you use the car. Major operators in the United States include Zipcar, Car2Go, Turo, and regional services like Maven (General Motors) and Gig (BMW), though availability varies by city.
Car share works best for people who need occasional transportation but do not want the cost and hassle of car ownership. If you drive daily or live in a rural area with no car share network, traditional rental or ownership is usually cheaper. The math changes depending on where you live, how often you drive, and whether you already own a car you could sell.
Key Takeaways
- Car share membership typically costs $10 to $20 per month, with hourly rates between $8 and $15 depending on the vehicle type and operator.
- You need a valid driver's license, proof of insurance, and a credit card to join most services, and membership approval usually takes one to three business days.
- Gas, insurance, and maintenance are included in the hourly rate, so you pay nothing extra unless you return the car late or damage it.
- Cars are parked in fixed locations throughout your city; you cannot pick one up from your home unless you live near a designated parking spot.
- Car share saves money compared to car ownership if you drive fewer than 10,000 miles per year, but costs more than owning if you drive daily.
How membership and hourly rates work
Most car share services charge a monthly membership fee between $10 and $20, though some offer annual plans at a discount. Once you join, you reserve a car through the app, walk to its parking spot, unlock it with your phone, and drive. Hourly rates typically run $8 to $15 depending on the vehicle — compact cars cost less than SUVs — and daily rates are usually available at a discount, often $50 to $80 for 24 hours.
You are charged from the moment you unlock the car until you return it to a designated spot and end the reservation through the app. If you return the car late, most services charge an overage fee, usually $5 to $10 per 15 minutes. Some operators offer monthly plans where you prepay for a set number of hours at a lower per-hour rate, which can reduce costs if you drive regularly.
Mileage is unlimited on most services — you do not pay per mile. Gas is included, and the company handles refueling at designated stations or through contracted partners. If you return a car on empty, you may face a refueling fee of $5 to $15.
What you need to join and how long approval takes
To join a car share service, you need a valid driver's license, proof of insurance (your own or the service's), and a credit card for billing. Some services require you to be at least 21 years old; others set the minimum at 18. A few operators check your driving record and may decline membership if you have recent serious violations or at-fault accidents.
The membership process is usually online and takes 10 to 15 minutes to complete. Approval typically happens within one to three business days, though some services approve when ready. Once approved, you can reserve a car when ready through the app. You do not need to visit an office or sign a physical contract with most operators.
If you are declined, the service will usually tell you why — often a driving record issue or a problem with your credit card. You can dispute inaccurate information on your driving record through your state's Department of Motor Vehicles before reapplying.
Insurance and liability: what is covered and what is not
Car share services provide liability insurance that covers damage you cause to other vehicles or property while driving. This coverage is mandatory and included in your hourly rate. However, damage to the car share vehicle itself is your responsibility, and you will be charged for repairs.
Most services offer optional damage waiver coverage for $10 to $15 per day, which reduces or eliminates your out-of-pocket cost if you damage the car. Without it, you may owe the full repair bill, which can reach several thousand dollars for major damage. Some credit cards cover rental car damage if you charge the rental to that card — check your card's benefits before paying for the waiver.
Your personal auto insurance does not cover car share vehicles because you do not own them. If you have an accident, the car share service's insurance handles third-party claims, but you are responsible for damage to the shared vehicle unless you purchased their damage waiver.
Where cars are located and how to find one nearby
Car share vehicles are parked in designated spots throughout your city — usually on streets, in parking lots, or in garages. The app shows you every available car within a map radius you set, typically one to three miles. You can reserve a car up to 30 minutes before you need it, or book it for later in the day.
Availability varies by neighborhood and time of day. Downtown areas and transit hubs usually have more cars; residential neighborhoods may have few or none. During rush hour or weekends, popular vehicles may be fully booked. If no cars are available when you need one, you have to wait for someone to return a vehicle or try a different service.
Some services allow you to extend your reservation if the car is not booked by the next user, but you cannot may provide a car will be available when you arrive at the parking spot. If you arrive and the car is gone, the app will show you the next nearest vehicle.
Car share versus car ownership: when each makes financial sense
Car ownership costs roughly $0.50 to $0.70 per mile when you add up the car payment, insurance, gas, maintenance, and registration. Car share costs roughly $0.30 to $0.50 per mile at typical usage rates. If you drive fewer than 10,000 miles per year, car share is usually cheaper. If you drive 15,000 miles or more per year, owning a car is usually cheaper.
Car share also makes sense if you live in a dense urban area with good public transit and only need a car occasionally — for groceries, trips outside the city, or moving furniture. It does not make sense if you commute by car daily, live in a suburb with no transit, or need a car you can access from home at any time.
If you already own a car, car share can reduce your costs by letting you sell it and use car share for occasional trips. The money you save on the car payment, insurance, and maintenance often exceeds the cost of car share membership and hourly fees.
Restrictions, penalties, and what happens if you break the rules
Car share services prohibit smoking, eating, or allowing pets in the vehicle unless the service explicitly allows it. You cannot drive outside a designated service area, usually defined as the city or region where the company operates. Driving outside this area triggers a penalty fee, typically $50 to $100, plus additional charges for retrieval.
If you return a car dirty, you may be charged a cleaning fee of $15 to $50. If you damage the car, you are billed for repairs; minor damage like a dent may cost $500 to $2,000, while major damage can exceed $5,000. If you are in an accident, you must report it through the app when ready and provide photos and a police report if required.
Repeated violations — late returns, damage, or driving outside the service area — can result in membership suspension or termination. If your account is terminated, you will owe any outstanding charges and will not be able to rejoin for a set period, often six months to a year.
Frequently Asked Questions
Do I need my own car insurance to use car share?
No. Car share services provide liability insurance as part of your membership. Your personal auto insurance does not explore to shared vehicles. However, if you want coverage for damage to the car share vehicle itself, you can purchase the service's optional damage waiver or check whether your credit card offers rental car coverage.
What happens if I get a parking ticket or traffic violation while using a car share vehicle?
You are responsible for any parking tickets or traffic violations you receive. The car share service will forward the ticket to you, and you must pay it. Repeated violations can result in membership suspension. If you receive a speeding ticket or other moving violation, it goes on your driving record, not the service's.
Can I use car share if I do not have a credit card?
Most car share services require a credit card for membership and billing. Some may accept a debit card, but this is rare. If you do not have a credit card, contact the service directly to ask about alternatives, though options are limited.
Is car share cheaper than renting a car from a traditional rental company?
For short trips of a few hours, car share is usually cheaper because you pay only for the time you use the car. For full-day or multi-day rentals, traditional rental companies are often cheaper, especially if you book in advance. Compare prices for your specific trip before deciding.
What if I need a car but there are no vehicles available in my area?
If no car share vehicles are available, you can try a different service if one operates in your area, use a traditional rental company, or use a ride-hailing service like Uber or Lyft. Some cities have multiple car share operators, so checking all of them increases your chances of finding an available vehicle.
