Authorities say Curry was driving a black Porsche when the driver of a Lexus lost control and struck his car.
Curry stopped in the center median, and as he waited for officers to arrive, another sedan lost control and rear-ended his Porsche about 10 minutes later, according to California Highway Patrol Officer Herman Baza.
Baza said no one was injured or arrested and that rain was a factor in the crash.
Curry, who made it to the team practice facility for shootaround after the crash, later tweeted his thanks.

"He was a little shaken up like anybody would be getting into a car accident, but thankfully nobody was hurt and Steph's doing fine," said Kerr, who joked that Curry probably "has another car that he can drive."
Curry has been out for the Warriors since Nov. 8 as he continues to recover from a strained left groin. He did not play Friday and also will miss Saturday's game against the Sacramento Kings. Curry has been getting more individual work in during the past week, and the team expects to update his status Saturday.
"They're both coming along," Kerr said. "They're both on the bike today doing a lot of conditioning stuff and on the floor after that getting jump shots up, so they're both doing well ...."
Warriors center DeMarcus Cousins remains out as he continues to rehab an Achilles injury. Cousins has not played yet this season, but Kerr noted that the All-Star center is progressing nicely.
"I don't have any update in terms of when he might play," Kerr said. "He's continuing to build strength in his rehab program with Rick [Celebrini], I talked to him today about it. And that has to go hand in hand with the conditioning. The conditioning needs to come with more court time, more scrimmage time. We have so many games bunched up right now that we haven't had a chance to really get DeMarcus into a scrimmage situation. So that will be coming and we'll have an update for you probably next week."
