Speed Limits

These are the speed limits in the City of Lakewood:

  • 25 mph in a business district
  • 30 mph in a residential district
  • 15 mph in an alley  


The City engineer may increase or decrease the speed limit on city streets if there are road features that affect safety. For example, the speed limit on Garrison St. is 35 mph except in those sections that have multiple driveways with access to the street. In those areas, the speed limit is 30.


I want the speed limit lowered on my street. Will the City do that?

Many people think that lowering the speed limit on their street will lead to drivers driving more slowly.  However, an unrealistically low speed limit can actually lead to crashes. Here's why:

  • First, national studies have shown that a driver's speed is influenced more by the appearance of the roadway and the traffic conditions than it is by the posted speed limit.

  • Second, some drivers would obey the lower posted speed, while others would believe it's unreasonable and simply ignore it. This would disrupt the traffic flow and actually increase the potential for crashes between the faster and slower drivers.

  • Third, when traffic is moving at different speeds, there are fewer breaks in traffic that permit safe crossing. Pedestrians have greater difficulty judging the speed of approaching vehicles, which may result in an increase in vehicle/pedestrian crashes.


Traffic engineers may post other speed limits—those between 25 and 55 miles per hour.  But these speed limits are always based on traffic engineering studies that include an analysis of roadway conditions, crash history and the typical speed of prudent drivers. 

Studies show that motorists tend to pay little attention to speed limit signs they consider unreasonable unless there is a very high degree of enforcement by police. The majority of drivers will disregard speed limits that are set too low.
