A dramatic chain-reaction accident that blocked San Francisco traffic this weekend is now being investigated as a case of drunk driving. A 37-year-old Colma man was arrested for driving under the influence following a four-vehicle accident that closed the Golden Gate Bridge. Three people were hospitalized with moderate injuries after two Mercedes collided and spun out of control, drawing two other vehicles into the accident.

According to the California Highway Patrol, the driver, who was eventually charged with driving under the influence of alcohol, rear-ended the vehicle in front of him in the southbound lanes of U.S. 101 about mid-span on the bridge. Both were driving Mercedes, which spun out and crossed over into oncoming traffic resulting in additional collisions.

One vehicle that was hit, a van, overturned during the crash after it ran into the side of the bridge. All of the drivers but the accused were injured and treated for non-serious injuries at nearby hospitals.

Law enforcement officials indicate that the accident happened about 8:10 p.m. on a busy Sunday evening. The multi-vehicle accident blocked both northbound and southbound lanes of U.S. 101 for about an hour.

Unfortunately accidents caused by intoxicated drivers often cause serious injuries. Many times the driver is travelling at excessive speeds and fails to attempt to slow down or stop before the collision. Every driver on the road has a duty to every other individual to drive in a safe and sober manner so as not to put other drivers unduly at risk.
