Happy holidays. Now pull over to the side of the road.

Motorists may be in for a surprise if they spot flashing red lights in their rearview mirrors in this Sacramento suburb during the holiday season.

Police are stopping law-abiding motorists and rewarding their good driving with $5 Starbucks gift cards.

A traffic officer came up with the idea to "promote the holiday spirit and enhance goodwill between the traffic unit and the motoring public," police Sgt. Tim Curran said.

Local businesses donated money to buy the gift cards.

"They raised a substantial amount of money," Curran said. "They'll be pulling over a lot of people."
