UPDATE Information Release To Fatal Traffic Collision


On May 24, 2013, 37-year-old Mountain View resident Conan Cheung was arrested at the Mountain View Police Department for one count of vehicular manslaughter. The District Attorney’s Office issued a warrant for Cheung’s arrest, and he turned himself in to the Mountain View Police Department. Cheung immediately posted bail in the sum of $10,000.

Drugs and alcohol were not a factor in this collision. The primary cause of the collision was failure to maintain a vehicle on the roadway.

In recent months, the Mountain View Police Department has been working to improve bicycle and pedestrian safety and has conducted several decoy operations targeting vehicles that do not yield to pedestrians at intersections and in crosswalks. California law requires drivers to yield to pedestrians in a crosswalk.

Pedestrian safety is a serious issue. The California Drivers Handbook says the following about pedestrians and crosswalks:

In California, pedestrian deaths occur in approximately 19 percent of all traffic fatalities. Drive cautiously when pedestrians are near because they may suddenly cross your path. Pedestrians may be at risk walking near hybrid and electric vehicles because these vehicles are virtually silent while operating. Use extra caution when driving near pedestrians.

-Respect the right-of-way of pedestrians. Always stop for any pedestrian crossing at corners or other crosswalks, even if the crosswalk is in the middle of the block, at corners with or without traffic lights, whether or not the crosswalks are marked by painted lines.
-Do not pass a vehicle that has stopped at a crosswalk. A pedestrian you cannot see may be crossing the street. Stop, then proceed when all pedestrians have crossed the street.
-Do not drive on a sidewalk, except to cross it to enter or exit a driveway or alley. When crossing, yield to all pedestrians.
-Do not stop in a crosswalk. You will place pedestrians in danger.
-Remember, if a pedestrian makes eye contact with you, he or she is ready to cross the street. Yield to the pedestrian.
-Allow older pedestrians, disabled pedestrians and pedestrians with young children sufficient time to cross the street.

A crosswalk is the part of the roadway set aside for pedestrian traffic. Most intersections have a pedestrian crosswalk whether or not lines are painted on the street. Most crosswalks are located at corners, but they can also be located in the middle of the block. Before turning a corner, watch for people about to cross the street. Pedestrians have the right-of-way in marked or unmarked crosswalks.

Crosswalks are often marked with white lines. Yellow crosswalk lines may be painted at school crossings. Most often, crosswalks in residential areas are not marked. Some crosswalks have flashing lights to warn you that pedestrians may be crossing. Look for pedestrians and be prepared to stop, whether or not the lights are flashing.

On Wednesday April 3, 2013 at approximately 4:25 p.m. a pedestrian was struck by a vehicle on Central Expressway near Rengstorff Ave in Mountain View. The pedestrian (an 81 year old female) was walking on the sidewalk on Central Expressway east of Rengstorff Ave, when she was struck by a vehicle that left the roadway as it traveled westbound on Central Expressway. The pedestrian suffered major injuries and was transported to Stanford Hospital. On Saturday April 6, 2013 the pedestrian died as a result of her injuries. The adult male driver of the vehicle (a gray 2012 Honda Odyssey) remained at the scene and has been cooperative in the investigation. Both parties are residents of Mountain View. Alcohol and speed are not believed to be factors in the collision. The Mountain View Police Department is investigating the collision to determine a cause. Upon conclusion, as is the case on all fatal collisions, the investigation will be forwarded to the District Attorney’s Office for review.

The Mountain View Police Department is seeking the public’s assistance and is asking that anyone who may have witnessed the collision to contact the Mountain View Police Department. Investigators can be reached at 650-903-6344.
