SAN FRANCISCO — Three Muslim families have filed complaints against an amusement park chain in California that they say barred them from riding go karts wearing headscarves, family advocates said Tuesday.

The families claim that Boomers! Parks in two locations in the state violated their civil rights with an unfair safety policy that bans all headgear on the rides, said Sammar Miqbel, a spokeswoman for the Council on American-Islamic Relations, which filed the complaints on behalf of the families.

The United Sikh’s organisation said it was preparing to file a similar complaint on behalf of a Sikh family.

CAIR’s Miqbel said the families visiting Boomers’ in the San Francisco suburb of Livermore and the Los Angeles suburb of Irvine had been allowed to wait in line for go karts, but were barred when they reached the front of the queque.

“We share their safety concerns,” Miqbel said. “We just ask that Boomers approach this (in a way) that won’t exclude an entire group of people.”

The parks ban all headwear on go kart rides because it could get caught and injure a rider, said Michele Wischmeyer, a spokeswoman for Palace Entertainment Holdings, which owns Boomers. Scarves and baseball caps alike are also not allowed, she said.

“It’s not a matter of discrimination, race or religion,” Wischmeyer said. “It’s a matter of safety.”

CAIR filed two complaints with the state Department of Fair Employment and Housing on Monday, while a third was filed last month, she said. It is also preparing to file another complaint.

Boomers, which has parks in 11 California cities, in addition to locations in New York and Florida, features carousel rides, miniature golf and laser tag.
