Danger plates (W401, TW401) and delineator plates (W402, TW402)

What it means

Hazard Marker: Used to mark the edge of an obstruction or road narrowing. Pass on the side indicated by the sloping stripes.

What to do

  1. Register which side the stripes protect and steer to the open side of the plate.
  2. Slow down if you are unsure of the clearance, especially at night or in rain.

In the K53 test

The plate stands ON the obstruction, not ahead of it. Answers that treat it as an advance warning are wrong: by the time you see it, the hazard is right there.

Where you will see it

Especially in rural areas, at an obstruction or where the road alignment changes; do not pass on the wrong side of the plate.
