Energex are appealing to drivers to heed warnings and signs around roadside power line works.

After a couple of close calls, Energex crews are urging south east Queenslanders to take care. 

Executive General manager of operations Paul Jordon says with 178,000 kilometres of overhead power lines and 29,000 kilometres of underground cable, it's not unusual to come across these roadside works. 

Mr Jordan says thankfully most drivers are following warnings, but appeals for caution as it only takes one reckless driver to cause an accident.
