Utahns are buckling up more often.

Seat belt use has more than doubled since 1986, according to Kathy Nutter, coordinator of the Occupant Protection Program for the State Department of Health.In 1990, 39 percent of adult drivers and front seat passengers observed in city driving were buckled up. In 1989, a similar study noted only 34 percent were wearing seat belts.

Utah's highways also see more belt-wearers. Last year, 73 percent of drivers wore restraints, up from 65 percent the year before.

Urban drivers are more likely to wear seat belts than their rural counterparts, 43 percent to 31 percent, while women drivers are more likely to buckle up than men drivers.

Children under the age of 2 are much less likely to be legally restrained than are children ages 2 to 5, 17 percent to 66 percent.

State statistics say that of the 255 Utahns killed in automobile crashes in 1989, 87 percent were not wearing any safety restraints.
