Turn Restriction Signs

Description
Signs may be installed which prohibit certain movements at an intersection, e.g., “No Left Turn”. This measure is applicable on streets where cut-through traffic exists. This method can be tailored to be applicable during the most problematic times by defining a time period for the restriction.

Issues Addressed

  • Cut-through traffic


Applications

  • Local streets, local collectors, collectors, and arterials.

Advantages 

  • Reduces cut-through traffic.
  • Redirects traffic to collector or arterial streets.
  • Can address time-of-day problems.
  • Inexpensive to install.


Disadvantages

  • Requires voluntary compliance.
  • May require ongoing police enforcement.
  • May increase trip length for drivers.
  • May divert traffic to parallel streets without turn restrictions.
  • Contributes to sign clutter.


Evaluation Considerations

  • Need to determine whether sign may significantly divert traffic to surrounding streets.

Design/Installation Considerations

  • Turn restrictions are most effective when limited to peak hours.
