Road Markings & The Don'ts

Yellow lines, U-turns, low-clearance bridges, and railroad crossings — what kills careers.

Summary

What you'll learn

  • Know your yellow lines — when to pass, when to stay.
  • Don't U-turn in a commercial vehicle.
  • Trust low-clearance signs, not your eyes.
  • Never stop on railroad tracks.
  • When in doubt, back up or call dispatch.
