California Highway Patrol officers in San Diego County made 22 drunk driving arrests in the first 12 hours of the holiday weekend, authorities announced Saturday.

The 22 arrests between 6 p.m. Friday and 6 a.m. Saturday marked a 38-percent increase from the same time last year, when the CHP made 16 drunk driving arrests in the county, CHP Officer Mary Bailey said.

No traffic deaths occurred in San Diego County during the first 12 hours of the Fourth of July holiday weekend last year, Bailey said.

Across the state, CHP officers made 263 drunk driving arrests Friday night and Saturday morning, down from 280 last year, Bailey said. But fatalities were up from seven last year to 10 this year.

Nine of the 10 reported deaths happened in CHP jurisdiction, including four people who were not wearing seat belts.
