Maybe it's time to petition for a speed hump.
The LADOT opens up a review cycle every 6 months so people can apply for a speed hump for their street.
Here are the kinds of streets that do qualify:
-Residential streets that have 1 lane for each direction
-Residential or Collector streets that have volumes of 1,000 to 10,000 vehicles per day
-Collector streets: these are streets "that are designed to provide access to residential properties".
-Streets with drainage gutters that are in the center of the roadway
-Roads with more than one lane in each direction
-Roads that are designated truck or transit routes, or adjacent to hospitals, fire stations, or policy facilities
We hope these quick facts were helpful. If you need more info, click this link to see if your neighborhood qualifies for a speed hump.
