Core facts about Oil Spill
Sign name	Oil Spill
Sign type	Supplementary Plates
Expected in DTT?	Yes. This sign is commonly covered in Irish driving theory test preparation.
Action required	Warning of oil contamination creating extremely hazardous slippery conditions requiring immediate speed reduction and gentle vehicle control inputs. Oil spills eliminate tire grip creating unpredictable vehicle behavior during braking, steering, and acceleration requiring specialized driving techniques and enhanced safety awareness until contamination cleared.
Appearance	Rectangular / White and black
Typical location	Oil spill supplementary plates positioned throughout Ireland at locations prone to fuel spillage including fuel stations, industrial areas, port facilities, busy truck routes, and areas near vehicle maintenance facilities where oil contamination creates dangerous slippery conditions. Critical for areas with heavy commercial vehicle traffic and industrial activities affecting road surface conditions.
