This one, however, could prove the biggest test yet for the 28-year-old who won the downhill at the 2010 Vancouver Olympics.
Vonn took a month off this season after being hospitalized for an intestinal illness in November, and had just regained her form with two wins last month.
That was evident at the start of her Tuesday's run. She led Maze by 0.04 seconds at the first checkpoint and was just 0.12 back at the second interval and seemingly on her way to a medal, if not victory.
Exactly what went wrong was debated by competitors and officials at the championships.
The start of the race was delayed by 3½ hours because of fog hanging over the course and it began in waning light at 2:30 p.m local time. Even before Vonn's crash, a course worker fell and also had to be airlifted. He was reported to have broken his nose.
All the delays made for what skiers call flat light — overcast and dreary conditions — when Vonn raced.
"Lindsey did a great job on top and Lindsey has won a lot of races in flat light so the flat light was definitely not a problem," U.S. Alpine director Patrick Riml told the AP.
"We are upset obviously with what happened but if you don't know the facts and why they decided to start and what the weather forecast was it's hard to say without any reasoning," Riml said. "And they probably had a reason, otherwise they wouldn't have started."
Atle Skaardal, women's race director for the International Ski Federation, defended the decision to go ahead with the event.
"I can confirm that the visibility was great, there were no problems, and the course was also in good shape," he said. "I don't see that any outside factors played a role in this accident. ... The other factors were like they were supposed to be for ski racing."
Vonn's list of injuries at major championships is long.
Two years ago, she pulled out midway through the last worlds in Garmisch-Partenkirchen, Germany, because of a mild concussion. At the 2010 Vancouver Olympics, Vonn skied despite a severely bruised shin to win the downhill and take bronze in the super-G.
At the 2009 worlds in Val d'Isere, she sliced her thumb on a champagne bottle after sweeping gold in the downhill and super-G, forcing her out of the giant slalom. At the 2007 worlds in Are, Sweden, Vonn injured her knee in training and missed her final two events.
And at the 2006 Turin Olympics, she had a horrific crash in downhill training and went directly from her hospital room to the mountain to compete in four of her five events.
The conditions Tuesday varied from racer to racer, and as the light began to fade even more, organizers stopped the race after only 36 of the 59 skiers had come down.
Maze skied immediately before Vonn.
"I saw it was a very high jump, so I knew I had to take the right line to make the next gate," she said. "World championship races often have special conditions and the mistakes from the girls were not because of the slope."
The two racers who started immediately after Vonn, former overall winner Maria Hoefl-Riesch of Germany and local favorite Anna Fenninger of Austria, each skied off course. In all, six women who started the course failed to finish. Still, Skaardal said he never thought about stopping the race.
"It's not a very difficult course but in some parts you couldn't see anything," said Fabienne Suter of Switzerland, who finished fifth.
Vonn's teammate Julia Mancuso also thrived in the difficult conditions and won the bronze medal.
"It's the same for everybody," U.S. speed coach Chip White said. "Everyone had to wait for a long time and that's always difficult. And the holds were every 15 minutes so it really doesn't give you a chance to go and do something else. You're always kind of on edge at the ready. It's a difficult situation but everybody had the same difficult situation."
Not long after Vonn was injured, NBC hosted a news conference in New York to discuss its coverage of the Sochi Games. A poster of a smiling Vonn hung in the room next to one of snowboarder Shaun White, evidence of the network's unsurprising expectations that she would be one of the biggest stars in Sochi.
The network's executives chose to put a positive spin on the injury.
"We expect her to be the comeback Olympian of the year," NBC Sports Group Chairman Mark Lazarus said.
