R5 Series — Prohibited Movement and Parking Signs
Regulatory Signs · CA MUTCD Part 2, Chapter 2B
The R5 Series covers regulatory signs that prohibit specific vehicle movements or restrict access. DO NOT ENTER (R5-1) and WRONG WAY (R5-2) are the most critical signs in this series for California work zones. They are used wherever a closed ramp, one-way lane, or wrong-way entry hazard exists — protecting drivers who might otherwise enter a work zone in the wrong direction.
California Field Use Notes
R5-1 is placed facing traffic at the entry point of a closed or one-way segment. R5-2 is placed further into the closed area facing wrong-way drivers who have already entered. Together they form the standard pairing for one-way operations, closed ramps, and contraflow lanes. Both signs must be reflective and sized to the roadway type per the CA MUTCD.
