22349 vc Description

22349 vc Description -  22349 vc is the California Vehicle Code Section that sets the maximum speed limit for all California roadways, which is 55 mph (22349 b vc) on two lane undivided roadways and 65 mph (22349 a vc) on all other roadways such as interstate highways or state highways. Any change of the maximum speed limits increase or decrease from these speed limits must be justified by an Engineering &Traffic Study (E&TS). 

22349 vc Description

For the purposes of 22349 vc description, the definition of an undivided highway is describes a roadway that has not been divided into two or more roadways by the installation of intermittent barriers or by a dividing section of not less than two feet in width, either unpaved or delineated by K-rails, physical curbs, striping double-parallel lines, or other markings on the roadway.

The logic behind setting speed limits is based on the premise that a reasonable speed limit is determined by the actual behavior of the majority of drivers on the roadways. Therefore, setting the speed limit on a roadway is the selected speed limit that is both reasonable and effective by measuring drivers' speeds. The majority of drivers are considered to be 85% od all drivers on the roadway. Thus, speed limits set by E&TS are normally set near the 85th percentile (or critical) speed. The 85th percentile speed is the speed at or below which 85 percent of the drivers are driving.

Studies of the effects of establishing, raising and lowering speed limits include federal studies FHWA-RD-92-084 and FHWA-RD-98-154.  Both of these studies show that the most effective effective way to determine the most reasonable speed limit is to determine the 85th percentile speed and set the posted speed close to that value. The empirical data in both of these studies shows that setting the speed limit too high or too low can result in an increase in the number of collisions.  Speed limits that are set at or near the 85th percentile (critical) speed of free flowing traffic are safer for the drivers and produce less variance in vehicle speeds.  Therefore, the 85th percentile is used to set the upper limit of the speed limit and it is considered reasonable and prudent.

Furthermore, if speed limits were set arbitrarily at lower speeds then a disproportionate number of drivers would be violators. This does not facilitate the orderly movement of traffic, and requires constant enforcement to maintain compliance. In addition, fighting speeding tickets that are issued in these types of speed zones can be easily contested. Many people in California use a process called trial by written declaration fight speeding tickets for 22349 vc. We provide more information for trial by written declaration tips and 22349 vc samples for trial by written declarations.

Regardless of the posted speed limit, the majority of drivers continue to drive at speeds at which they feel most comfortable.  A common question then arises as to “Why do we even need to post speed limit signs?” The answer is simple, posting speed limit signs:

• Provides feedback to the driver, if they are in the 85% majority of drivers who consider their speed safe and reasonable
• Allows for fairer enforcement for the drivers who exceed the speed limit or drive at an unreasonably lower speed than the 85% speed which drivers consider safe and reasonable.
• Establishes other design criteria for other traffic control devices such as; traffic signal timing, transition distance, location of ground loop detectors and many more
