     After Jon Corzine suffered serious injuries in a car accident on April 12, many of the reports focused on his

failure to wear a seat belt. It's reported that seatbelt use has gone up by 10 percent since 2000, hitting a record

81 percent nationwide in 2006. And the agency reports that safety belts saved about 15,434 lives in 2004. But

for some groups, particularly teens and young adults, usage still lags. Sixty-two percent of the 5,135 young

people ages 16 to 20 killed when riding in passenger vehicles (交通工具) in 2004 were not wearing safety belts.

So if you're the parent of a teen, remind them to fasten up every time they get into a car. Yes, even it's just for

a short ride and even if they're in the back seat. And for kids under 13, be sure to follow these safety guidelines

(准则).

     ● Children from birth until age 1 or under 20 pounds should ride in the back seat in a rear-facing (向后)

child safety seat.

     ● Children over 1 year old and weighing more than 20 pounds can ride in a forward-facing child safety seat

in the back seat.

     ● All children who have outgrown child safety seats should be properly put in booster seats (幼儿加高座位)

until they are at least 8 years old or 4 feet, 9 inches tall.

     ● Once children outgrow their booster seats, they can use an adult seat belt in the back seat as long as it fits

properly.

     ● New rules require manufacturers(制造商 )to start using"smart" air bags for all 2007 cars. The new air

bags are constructed so that they don't injure smaller passengers in the front seat.
