Regulatory, Lane & Parking SignsStandalone practice
The diagonal stripes on a barricade rail slope downward toward the left. On which side should traffic pass?
Correct answer: Pass on the left side
Why
Barricade stripes slope down toward the side traffic is to pass. These stripes slope down to the left, so pass on the left when the marked route is open and safe. Follow any additional signs, flagger directions or closure controls.
