If you worry about getting sick away from home, you may want to consider medical travel insurance. In most cases, however, your existing health plan will provide all the coverage you need, but be sure to carry your identification card in your wallet.

If you suffer from a chronic illness, consult your doctor before your departure. Pack prescription medications in your carry-on luggage, and carry them in their original containers, with pharmacy labels—otherwise they won’t make it through airport security. Visitors from outside the U.S. should carry generic names of prescription drugs. For U.S. travelers, most reliable healthcare plans provide coverage if you get sick away from home. Foreign visitors may have to pay all medical costs upfront and be reimbursed later.

Safety

For a big city, San Francisco is relatively safe and requires only that you use common sense (for example, don’t leave your new video camera on the seat of your parked car). However, in neighborhoods such as Lower Haight, the Mission, the Tenderloin (a few blocks west of Union Square), and Fisherman’s Wharf (at night especially), it’s a good idea to pay attention to yourself and your surroundings.

Avoid carrying valuables with you on the street, and don’t display expensive cameras or electronic equipment. Hold on to your pocketbook, and place your billfold in an inside pocket. In theaters, restaurants, and other public places, keep your possessions in sight.

Remember also that hotels are open to the public, and in a large hotel, security may not be able to screen everyone entering. Always lock your room door—don’t assume that inside your hotel you are automatically safe.

Driving safety is important, too. Ask your rental agency about personal safety, and ask for a traveler-safety brochure when you pick up your car. Ask for written directions to your destination or a map with the route clearly marked. (Many agencies offer the option of renting a cellphone for the duration of your car rental; check with the rental agent when you pick up the car.) Try to arrive and depart during daylight hours.

Recently, more crime has involved cars and drivers. If you drive off a highway into a doubtful neighborhood, leave the area as quickly as possible. If you have an accident, even on the highway, stay in your car with the doors locked until you assess the situation or until the police arrive. If you’re bumped from behind on the street or are involved in a minor accident with no injuries, and the situation appears to be suspicious, motion to the other driver to follow you. Never get out of your car in such situations. Go directly to the nearest police precinct, well-lit service station, or 24-hour store.

Always try to park in well-lit and well-traveled areas. Never leave any packages or valuables in sight. If someone attempts to rob you or steal your car, don’t try to resist the thief or carjacker. Report the incident to the police department immediately by calling tel. 911. This is a free call, even from pay phones.
