There are two basic north-south routes in California: Interstate 5 runs inland most of the way from the Oregon border to the Mexican border; and U.S. 101 hugs the coast for part of the route from Oregon to Mexico. A slower but much more scenic option is to take California State Route 1, also referred to as Highway 1 and the Pacific Coast Highway, which winds along much of the California coast and provides an occasionally hair-raising, but breathtaking, ride.
From north to south, the state's east-west interstates are Interstate 80, Interstate 15, Interstate 10, and Interstate 8. Much of California is mountainous, and you may encounter winding roads, frequently cliff-side, and steep mountain grades. In winter, roads crossing the Sierra from east to west may close at any time due to weather. Also in winter, Interstate 5 north of Los Angeles closes during snowstorms.
The flying and driving times in the accompanying charts represent best-case scenario estimates, but know that the infamous California traffic jam can occur at any time.
Gasoline prices in California vary widely, depending on location, oil company, and whether you buy it at a full-service or self-serve pump. It's less expensive to buy fuel in the southern part of the state than in the north. If you're planning to travel near Nevada, you can save a bit by purchasing gas over the border. Gas stations are plentiful throughout the state. Most stay open late (24 hours along major highways and in big cities), except in rural areas, where Sunday hours are limited and where you may drive long stretches without a chance to refuel.
Rainy weather can make driving along the coast or in the mountains treacherous. Some of the smaller routes over mountain ranges and in the deserts are prone to flash flooding. When the rains are severe, coastal Highway 1 can quickly become a slippery nightmare, buffeted by strong winds and obstructed by falling debris from the cliffs above. When the weather is particularly bad, Highway 1 may be closed due to mud and rock slides.
Many smaller roads over the Sierra Nevada are closed in winter, and if it's snowing, tire chains may be required on routes that are open, most notably those to Yosemite and Lake Tahoe. From October through April, if it's raining along the coast, it's usually snowing at higher elevations. Consider renting a four-wheel-drive vehicle, or purchase chains before you get to the mountains. (Chains or cables generally cost $30 to $70, depending on tire size; cables are easier to attach than chains, but chains are more durable.) If you delay and purchase them in the vicinity of the chain-control area, the cost may double. Be aware that most rental-car companies prohibit chain installation on their vehicles. If you choose to risk it and do not tighten them properly, they may snap—your insurance likely will not cover any resulting damage. Uniformed chain installers on Interstate 80 and U.S. 50 will apply them at the checkpoint for $35 or take them off for less than that. Chain installers are independent business people, not highway employees, and set their own fees. They are not allowed to sell or rent chains. On smaller roads, you're on your own. Always carry extra clothing, blankets, water, and food when driving to the mountains in the winter, and keep your gas tank full to prevent the fuel line from freezing.

Dial 911 to report accidents on the road and to reach the police, the California Highway Patrol (CHP), or the fire department. On some rural highways and on most interstates, look for emergency phones on the side of the road. In Los Angeles, the Metro Freeway Service Patrol provides assistance to stranded motorists under nonemergency conditions. Call #399 on your cell phone to reach them 24 hours a day.
Rules of the Road
All passengers must wear seat belts at all times. A child must be secured in a federally approved child passenger restraint system and ride in the back seat until at least eight years of age or until the child is at least 4 feet 9 inches tall. Children who are eight but don't meet the height requirement must ride in a booster seat or a car seat. Unless otherwise indicated, right turns are allowed at red lights after you've come to a full stop. Left turns between two one-way streets are allowed at red lights after you've come to a full stop.
Drivers with a blood-alcohol level higher than 0.08 who are stopped by police are subject to arrest, and police officers can detain those under 21 with a level of 0.05 if they appear impaired. California's drunk-driving laws are extremely tough—violators may have their licenses immediately suspended, pay hefty fines, and spend the night in jail.
The speed limit on many interstate highways is 70 mph; unlimited-access roads are usually 55 mph. In cities, freeway speed limits are between 55 mph and 65 mph. Many city routes have commuter lanes during rush hour.
Those 18 and older must use a hands-free device for their mobile phones while driving; those under 18 may not use mobile phones or wireless devices while driving. Texting on a wireless device is illegal for all drivers. Smoking in a vehicle where a minor is present is an infraction. For more information refer to the Department of Motor Vehicles driver's handbook at www.dmv.ca.gov.
When you reserve a car, ask about cancellation penalties, taxes, drop-off charges (if you're planning to pick up the car in one city and leave it in another), and surcharges (for being under or over a certain age, for additional drivers, or for driving across state or country borders or beyond a specific distance from your point of rental). All of these things can add substantially to your costs. Request car seats and extras such as GPS when you book.
Rates are sometimes—but not always—better if you book in advance or reserve through a rental agency's website. There are other reasons to book ahead, though: for popular destinations, during busy times of the year, or to ensure that you get certain types of cars (vans, SUVs, exotic sports cars).
Make sure that a confirmed reservation guarantees you a car. Agencies sometimes overbook, particularly for busy weekends and holiday periods.
A car is essential in most parts of California, though in compact San Francisco it's better to use public transportation to avoid parking headaches. In sprawling cities such as Los Angeles and San Diego, however, you'll have to take the freeways to get just about anywhere.
Rates statewide for the least expensive vehicle begin as low as $30 a day, usually on weekends, and less than $200 a week (though they increase rapidly from here). This does not include additional fees or the tax on car rentals, which is 8.75% in Los Angeles, 8.5% in San Francisco, and 7.75% in San Diego. Be sure to shop around—you can get a decent deal by carefully shopping the major car rental companies' websites. Also, rates are sometimes lower in San Diego; compare prices by city before you book, and ask about "drop charges" if you plan to return the car in a city other than the one where you rented the vehicle. If you pick up at an airport, there may also be a facility charge of as much as $12 per rental; ask when you book.
In California, you must have a valid driver's license and be 21 to rent a car; rates may be higher if you're under 25. Some agencies will not rent to those under 25; check when you book. Non-U.S. residents must have a license with text that is in the Roman alphabet that is valid for the entire rental period. Though it need not be entirely written in English, it must have English letters that clearly identify it as a driver's license. In addition, most companies also require an international license; check in advance.
If you dream of driving down the coast with the top down, or you want to explore the desert landscape not visible from the road, consider renting a specialty vehicle. Agencies that specialize in convertibles and sport-utility vehicles will often arrange airport delivery in larger cities. Unlike most of the major agencies, the following companies guarantee the car class that you book.
