Speed bumps are 12 foot wide by 3 inch
high asphalt undulations which are usually placed across roadways between intersections. They
are requested by residents as a means to slow down
traffic in residential neighborhoods.
Benefits
Speed Bumps may:
Reduce traffic speeds in the immediate vicinity of
the speed bumps.
Decrease traffic volume.
Drawbacks
Speed Bumps may:
Present a potential hazard to bicyclists and
motorcyclists.
Increase response time of emergency vehicles where
seconds may be critical.
Increase noise level due to vehicle brakes, tires
and engine.
Increase vehicle emissions due to deceleration and
acceleration.
Conflict with school and transit bus operation.
Provide an attractive nuisance.
Divert traffic to other neighborhood streets.
How do I Request Speed Bumps on my Street?
A Neighborhood Traffic
Management Program (NTMP) petition
must be submitted to the Department of
Transportation, signed by at least ten (10)
households residing on each subject street.
The Traffic Engineering Section evaluates and
ranks the street with other petitioner to be
placed on the NTMP list submitted to the
Sacramento County Board of Supervisors for
funding twice per year for single streets and
once per year for neighborhood wide petitions.
