The primary hazard is the overhead electrical line itself. It can be dangerous due to electricity arcing across short distances, even if your vehicle doesn't touch the line. This is especially risky for tall vehicles, cranes, or loads carried high above the vehicle.
If you're in a tall vehicle or carrying a high load, you must assess if there is sufficient clearance. If there's any doubt, it's best to stop and check, or seek an alternative route. Never assume it's safe to pass without verifying the height clearance.
Yes, the J3 sign effectively prohibits driving under the line with raised equipment or a load that exceeds a safe height. It also prohibits assuming the lines are safe to pass without proper clearance and prohibits stopping or positioning your vehicle where it increases exposure or risk.
For the theory test, understanding the J3 sign means recognising the serious danger posed by overhead power lines. You must know that it's your responsibility to ensure safe passage, especially with tall vehicles, and that failure to do so can have severe consequences. Expect questions about appropriate reactions and precautions.
No, it is strongly advised against stopping directly under an overhead power line indicated by the J3 sign. Stopping in such a location can increase your exposure to danger and potentially obstruct traffic, especially if your vehicle is tall or if you need to raise equipment.
