Of these, 400, or 48.1 percent, exceeded .10 percent by weight, the legal presumptive level. Young drivers, aged 24 years and under, accounted for 46.4 percent of all had been drinking drivers in fatal accidents. Results show that the younger drinking drivers had lower levels of alcohol in their blood, yet had higher involvement in fatal accidents, strongly suggesting that young drivers are more vulnerable to traffic accidents when drinking is involved. On the other hand, the blood alcohol concentration level among the middle-age drinking drivers was higher, yet their involvement in traffic accidents is lower.

Thre of these counties had 2 fatal accidents and one had 5 fatal accidents. Of the total fatal traffic accidents being alcohol related, there were 51 counties above the state average of 49.0 percent. Of the total fatalities being alcohol related, there were 37 counties above the state average of 50.0 percent.
