Aspen police cited Armstrong with failing to report an accident and speeding weeks after the Dec 28 accident, but only after his girlfriend, Anna Hansen, admitted to lying for him.
Armstrong declined immediate comment, and his attorney, Pamela Mackey, didn't immediately return a call.
Hansen initially told police she had been driving home from an Aspen Art Museum party when she lost control of Armstrong's GMC Yukon on the icy roads, hitting the cars. She said she drove because "Lance had a little bit to drink," according to the reports.
"She said, 'I'm Anna, we're the Armstrongs, my husband's Lance, he was just driving maybe too fast around the corner or something,'" the man told police, according to the reports.

He called 911 to report a hit-and-run. Hansen and Armstrong left the scene before police arrived.
Detectives later interviewed Hansen, who eventually told them Armstrong was driving, but they had both decided to let her take the blame.
Failure to report an accident is a misdemeanor punishable by up to 90 days in jail and a fine of between USD 150 and USD 300. Driving too fast for conditions is punishable by a fine between USD 15 and USD 100.
The Aspen Daily News first reported the citation.
Armstrong won the Tour de France every year from 1999-2005. Those titles were stripped after a massive report by the US Anti-Doping Agency detailed the use of performance enhancing drugs by Armstrong and his US Postal Service teammates.
