PALOMAR MOUNTAIN -- Twenty-three motorists were cited during a period of "zero tolerance" enforcement on Palomar Mountain on Sunday, a California Highway Patrol officer said.

The CHP used a plane and nine units of officers, as well as three sheriff's units, during several hours to crack down on speeding and reckless driving on the mountain, which has "problems every weekend," Sgt. Scott Payson said.

No accidents were reported during the enforcement period, CHP officer Tom Kerns said.

The mountain's windy roads are a popular spot for motorcyclists to congregate, and "there's total disregard on both sides" as cars and motorcycles compete for the road, Payson said.

However, the patrols successfully decrease speeding and accidents when officers "are out and about," and motorists know they are being monitored, Kerns said.

The enforcement is provided by grant money that allows overtime for sporadic patrols, Kerns said.
