More warning signs flag changes in traffic flow, crossings by people, animals and vehicles, and road work. A few are special shapes worth memorizing.

Traffic-flow and roadway warnings:

  • Advisory speed plate: the top safe speed for the turn
  • Chevron: sharp turn or curve in the arrow's direction; usually placed in a series
  • Low shoulder: the shoulder is much lower than the road surface
  • PAVEMENT ENDS: the surface changes to gravel or dirt ahead
  • DEAD END: the street has no outlet
  • Lane ends: lanes change ahead; three signs in a series remind you to merge
  • Truck crossing or fire station: watch for trucks or fire trucks entering the road
  • Railroad crossing ahead: slow down, look both ways and be prepared to stop

  • Low clearance: vehicles or loads higher than shown can't pass under the structure ahead
  • Two-way traffic: you're leaving a one-way roadway and entering a two-way road
  • Merge: traffic from the right must yield to the main route and use speed-change lanes
  • Crossroad, divided highway ahead, divided highway ends, and downhill grade

Work zones:

  • ROAD CONSTRUCTION: watch for a flagman, one-way traffic, signs or obstructions

  • Flashing arrow panels guide you into certain lanes and warn that part of the road is closed

Put it into practice

You see a fluorescent yellow pedestrian crossing sign in the middle of a block. There's no intersection, but a crosswalk may be just ahead. Slow down, watch both sides of the street and yield to anyone in the crosswalk.
