Core facts about Overhead Electrical Cables
Sign name	Overhead Electrical Cables
Sign type	Warning Signs
Expected in DTT?	Yes. This sign is commonly covered in Irish driving theory test preparation.
Action required	Electrical power cables cross the road overhead at a height that may be insufficient for tall vehicles or raised equipment. Check the height restriction plate if present—typically showing clearances of 4-5 meters. If you are driving high vehicles, carrying tall loads, or operating vehicles with raised components (tipper trucks, cranes, agricultural equipment), verify your height before proceeding. Electrical contact can cause electrocution, fire, and explosion. If your vehicle touches cables, remain in the cab and call emergency services immediately. Do not exit unless fire forces evacuation.
Appearance	Triangular / Red and white
Typical location	Overhead electrical cable warnings appear where power lines cross roads at heights that pose risks to tall vehicles. Common at farm access roads where agricultural machinery with raised equipment operates, industrial areas with overhead power distribution, near electricity substations where cables cross entry roads, and on rural routes where power lines cross at lower heights than modern standards. Height clearance is typically marked on supplementary plates showing maximum safe height in meters.

This page explains what the Overhead Electrical Cables sign means, where it is typically found, and how drivers should respond in Ireland. It also connects you to closely related signs so you can compare similar road situations and build stronger theory-test recall.

Penalties & Legal Consequences

Striking overhead electrical cables due to failure to observe warning signs constitutes dangerous driving: 5 penalty points, fines to €5,000, imprisonment, and disqualification.

Beyond driving penalties, you face potential manslaughter charges if electrocution causes deaths, liability for power network damage (costs often exceeding €100,000), and prosecution under electrical safety regulations.

Commercial operators face additional charges under workplace safety legislation.

ESB Networks prosecutes cable strike incidents aggressively.

Appears in Driving Test?

Commercial vehicle license tests include detailed questions on height restrictions, overhead hazards, and the legal requirement to know your vehicle height at all times.

While standard car driving tests don't extensively cover commercial vehicle concerns, learners must understand that height restriction signs require attention and that some vehicles cannot safely pass under low cables.

Awareness of different vehicle types' specific hazards demonstrates comprehensive road safety knowledge.

Theory questions may test understanding that overhead cable warnings particularly affect agricultural and commercial vehicles.
