SAN FRANCISCO -- Two drivers suspected of driving under the influence were arrested following a fatal motorcycle crash that tied up two freeway ramps and mired traffic in San Francisco for about five hours on Tuesday morning.
The motorcyclist, a man in his 30s, was headed southbound on Highway 101 to eastbound I-80 about 3:30 a.m. when he was involved in a collision and was thrown from his motorcycle, according to the California Highway Patrol.
Authorities say he may have been trying to avoid a DUI crash and swerved off the connector, landing on a moving vehicle below on the westbound I-80 to southbound Highway 101 ramp.
