• 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.
