Some French tourists got a quick lesson in traffic laws in Green River this week. A Green River police officer attempted to make a traffic stop on a vehicle with Colorado license plates for speeding. The officer activated the emergency lights and siren, but the vehicle refused to pull over and stop. The car then drover up South Hill. The officer continued to follow with the lights and siren out to Blacks Fork's Bridge. Finally, the vehicle stopped on the bridge. The occupants, who were from France, did not hear the siren, but did see the emergency lights. They were not aware the lights meant to pull over.
