Excess Oil (Plaque)

Identifies that the slippery condition warned above is caused by excess oil on the pavement.

Mounted beneath a Slippery When Wet or similar warning, this supplemental plaque pins the cause to oil build-up on the road surface, often present after long dry spells, just after rain begins, or following recent oil-and-chip maintenance. Reduce speed, brake gently, and allow extra following distance until the affected segment ends.
