Local streets with residential driveway access in medium to high-density
communities have an enforceable prima facie speed limit of 25 miles per
hour. Vehicular speeds sampled on these streets indicate that most
vehicles travel between 28 and 32 miles per hour. Some motorists travel
faster! Teenagers and commuters are not the only ones who exceed the
speed limit. In fact, studies have shown that residents who are familiar
with the roadway characteristics and feel comfortable driving on them,
exceed the speed limit often. Typically, these are residents that are
late for work, in a hurry to pick up their children, or anxious to get
home.
