Visitors to Rocky Mountain National Park this Saturday should be prepared for an extra stop as the park is conducting safety checkpoints this weekend.

On Aug. 17, law enforcement patrols will increase and rangers will be checking for traffic violations, safety violations and impaired drivers at the safety checkpoint, according to Kyle Patterson, the spokesperson for the park.

Rocky Mountain National Park will be partnering with local law enforcement agencies for the safety checkpoints.

All park roads also require drivers and passengers to be wearing their seatbelts per federal law.

Patterson added that the park’s roads can be difficult to navigate because of heavy traffic, rapidly changing weather conditions and wildlife.

Rocky was also the nation’s third most-visited national park last year and park managers continue to address how its popularity impacts visitor and staff safety, resource protection, visitor experiences and operational capacity.
