PHOENIX -- Fifteen people were injured in a large rollover crash near Casa Grande, Ariz., on Friday.
The victims were hospitalized after a 15-passenger van crashed at milepost 194 on Interstate 10.
"This was a church van," said Arizona Department of Public Safety spokesman Bart Graves. "There was a heavy downpour. The vehicle hydroplaned. The driver lost control. The vehicle rolled over."
The passengers, primarily a number of young boys, sustained minor injuries.
A large dust storm was moving through the area at the time.
During dust storms, the visibility on I-10 drops to near-zero.
The Arizona Department of Transportation says motorists should avoid driving into dust storms in the first place by planning ahead and being prepared to change travel plans.
The driver-safety campaign advises motorists who find themselves in a dust storm to pull off the highway and park in a safe place off the pavement.
Other recommendations include turning off all lights, keeping your foot off the brake and staying in the vehicle while waiting for the storm to pass.
