Canada/Road signs/Alberta/Regulatory

This page lists Alberta regulatory road signs, which is divided into three subseries under the Traffic Sign Catalogue by Alberta Transportation and Economic Corridors:

  • RA - Right of way
  • RB - Control of movement
  • RC - Miscellaneous

Ra series (right of way)

MUTCDC sign code Image Description Tags Notes

RA-1-T File:CA-AB road sign RA-1-T.svg All-way (tab) stop=all
RA-2 Yield highway=give_way
RA-3 School crosswalk highway=crossing
RA-4 Pedestrian crosswalk highway=crossing

RA-6 Railway crossing (crossbuck) railway=level_crossing (most cases) or railway=crossing (crossings with pedestrian/bike paths)

Rb series (control of movement)
