  • Getting a rental car from the Ontario International Airport (ONT) is an ideal way to explore San Bernardino County, Riverside County, and Los Angeles County. At the arrivals curb for every terminal at ONT, you can board a complimentary shuttle that will take you to the ONT Rental Car Center. The rental vehicles are parked just outside the Rental Car Center customer service area. When it is time to return your rental vehicle, simply follow the Rental Car Return signs as you approach the airport.
  • Driving a rental car from Ontario International Airport (ONT) is a fantastic way to see everything Southern California has to offer. You can keep appointments and visit friends and family, and you can see the sites, from the Hollywood Walk of Fame to the Rose Bowl in Pasadena to the LA arboretum in Arcadia to Universal Studios in Studio City. In an ONT car rental, you can drive to the beaches in Santa Monica, to Disneyland in Santa Ana, up into the San Gabriel Mountains, or further east to Las Vegas.
  • A GPS navigation device would be an ideal add-on for an Ontario International Airport (ONT) rental car because it could help you navigate around Southern California’s notorious traffic. If you will be traveling with children in Ontario or Southern California, according to California law, all children who are riding in a vehicle and who are age seven and younger or four feet eight inches and shorter must be secured in a child safety seat appropriate for their size. So, be sure to mention add-ons when you make your reservation to ensure that what you need is available when you collect your car.

Car rental FAQs

Find answers to frequently asked questions about car rentals in Ontario Airport, including policies, requirements, and more. FAQs were last updated on June 12, 2025.
  • What should I know about driving in Ontario and the Los Angeles metropolitan area?

    In Southern California, there are a number of driving practices you should be aware of if you are driving a rental car from the Ontario International Airport (ONT). Generally, three cars turn left as soon as a traffic light turns red. If you are first in line at the red light, pull forward into the intersection, and as soon as the light turns red, make your left. On the freeways, people pass on the right and left and swerve in and out of traffic lanes, often without using signals. Drive cautiously on the freeway. And if you don't feel comfortable driving on the multi-lane freeways, use surface streets instead. Expect traffic congestion at any given hour of any given day in Southern California. Traffic comes to a virtual standstill during the peak rush hours of 6:30 am to 10 am and 3 pm to 7 pm. Stay vigilant of people on bicycles and motorcycles.

  • Do I need to worry about any weather when I’m driving a rental car in Ontario?

    You can often see rain in Ontario and the surrounding areas from November through April. When it rains in the Ontario area, roads become slick quickly because of all the dirt and oil on the blacktop. Drive with caution. Also, certain surface streets tend to flood quickly. Do not attempt to drive through a flooded area of the roadway, since you don't know how deep the water is or what is underneath the surface of the water. In high winds, try to avoid parking near trees. If you see any downed power lines, stay at least 300 feet away from them and never drive over them.

  • What should I do if I want to drive my Ontario International Airport (ONT) rental car into Mexico?

    If you want to drive your ONT rental car across the border into Mexico, clear it with the car rental agency first. Not all car rental agencies allow cross-border travel and those that do, often restrict certain cars from border-crossing, such as luxury or exotic vehicles. Furthermore, the car rental agency will have to arrange all the paperwork and insurance so that you are not stopped, turned back, or detained when you try to cross. At the border, you will have to show your valid US driver's license, your valid US passport, your rental car agreement, and your Mexican liability insurance that you will have to purchase from the car rental agency.
