COUNCIL COMMUNICATION
AGENDA TITLE: Kettleman Lane (State Highway 12) at Lee Avenue, "Do Not Block Intersection"
Signing Study
MEETING DATE: February 2, 1994
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council review the following information regarding the
installation of "Do Not Block Intersection" signing on Kettleman Lane
(State Highway 12) at Lee Avenue and take no action.
BACKGROUND INFORMATION: At its December 15, 1993 meeting, City Council directed staff to
review the installation of "Do Not Block Intersection" signing/markings
on Kettleman Lane at Lee Avenue. The concern is that westbound
vehicles stopped at the traffic signal at Hutchins Street back up
through the intersection of Lee Avenue (Exhibit A). These stopped vehicles restrict turning movements
both into and out of Lee Avenue. The Police Department has expressed a similar concern.
Per the California Vehicle Code (CVC), it is illegal to block an intersection. CVC Section 22526 states
that the driver of a vehicle shall not enter an intersection or marked crosswalk, notwithstanding any
official traffic control signal to proceed, unless there is sufficient space on the other side of the
intersection or marked crosswalk to accommodate the vehicle without obstructing through passage of
vehicles from either side. Signs or markings are not required for this restriction to be enforceable.
The signing of this restriction is addressed in the State of California Department of Transportation sign
policy. This policy indicates that the "Do Not Block Intersection" sign may be used in accordance with
CVC 22526 at intersections that have demonstrated a gridlock problem. There is no pavement marking
associated with this signing. The sign and corresponding policy is shown on Exhibit B. Gridlock is
defined as the inability of traffic to move, due to congestion, even if the traffic control indicates that the
drivers may proceed. "Keep Clear" signing and pavement marking, commonly mistaken for use at
intersections, is for use only at driveways to emergency service facilities such as fire, police or
ambulance. The only k>cations in the City where "Keep Clear" pavement markings have been installed
are at the driveways servicing Fire stations. Since the intersection of Kettleman Lane at Lee Avenue is
not a driveway to an emergency facility, this signing/marking would not be appropriate at this location,
nor would Caltrans allow its installation.
A review of available accident records in the 5 -year period from 1989 to 1993 indicates that there have
been 20 accidents at the intersection of Kettleman Lane and Lee Avenue. Of these 20 accidents, 14
involved vehicles entering or exiting Lee Avenue. Nine of these accident reports state that traffic on
Kettleman Lane provided an opening at Lee Avenue to allow cross -street traffic to proceed. In the
remaining 5 accidents, although the report did not specifically state that an opening was left for cross-

street traffic, it was implied by the driver statements. Based on the information from the accident
reports, it is safe to say that all or nearly all the accidents involving drivers entering or exiting
Lee Avenue were related to the opening provided by drivers on Kettleman Lane. Similar accidents
were reported at the driveway servicing the Beacon Service Station located west of Lee Avenue on
Kettleman Lane. Traffic volumes approaching the intersection of Kettleman Lane and on Lee Avenue
are 26,000 and 430 vehicles per day, respectively.
DISCUSSION: The Police Department's concern that the lack of signing or pavement markings makes
enforcement difficult is valid. In addition to being difficult to enforce, the Police Department indicated
that without signing only a parking citation could be issued. If signs are installed, the violation becomes
a moving violation because the driver is now failing to obey an official traffic control device. Even
though signing would change the violation to a moving violation, staff is reluctant to add the signing just
for that reason. Staffs concern is that since the opening drivers on Kettleman Lane are occasionally
providing for drivers on Lee Avenue is a factor in the accidents occurring at this intersection, stricter
enforcement of this restriction would increase the frequency of these accidents. Controlling multiple
lanes of traffic with this signing would be difficult and, as indicated in the accident reports, it cannot be
assumed that all of the drivers will stop for vehicles who might use the opening. This is particularly true
when all of the lanes of traffic are not backed up through Lee Avenue. An additional concern is that the
sign is designated for use at intersections that have a demonstrated gridlock problem. Since gaps for
Lee Avenue traffic generally appear after the Kettleman Lane traffic has cleared, this intersection does
not conform to the definition of gridlock.
Since this request is on the State Highway. Caltrans was contacted for their comments. Caltrans
indicated they would consider the "Do Not Block Intersection" signing (at the City's expense) but they
would not support the installation of pavement markings. They also confirmed that "Keep Clear"
signing and pavement marking is used only at driveways to emergency service facilities. While there
are locations on some State Highways where "Keep Clear" pavement markings are being used contrary
to policy, they are in the process of being phased out.
RECOMMENDATION: Based on the probable increase in accidents this intersection will experience if
an opening on Kettleman Lane is enforced, and that the back-up experienced at this intersection is not
consistent with the definition of gridlock, staff does not recommend the installation of "Do Not Block
Intersection" signing at this location. If Council wishes to pursue the installation of this signing, Caltrans
approval will be required.
FUNDING: Not applicable.
