YELLOWSTONE NATIONAL PARK, Wyo. (AP) -- Park rangers will conduct traffic safety checkpoints in Yellowstone National Park this holiday weekend.
The checkpoints are set up to identify and correct traffic and safety violations and to identify any impaired drivers.
Yellowstone has more than 300 miles of paved roads, and driving can be a challenge because of high traffic volume, stopped vehicles, rapidly-changing weather conditions, and wildlife and people on roadways.
The National Park Service says its rangers have seen an increase in impaired driving contacts over the past few years compared to previous years.
Drivers charged with driving under the influence in Yellowstone face prosecution in federal court and penalties that can include up to six months in jail and a $5,000 fine.
