This is the shocking moment electricity posts toppled onto a road when a truck snagged the power lines in Thailand.

The lorry carrying a cement mixer was passing through an intersection in Bangkok's Taling Chan District when it hit the low-lying electric cables on June 8.

Dramatic CCTV footage shows a traffic enforcer and a motorist running when an electric post collapsed right where they were standing. The accident also triggered small explosions from a power transformer.

Authorities said at least three poles had fallen, one of which smashed into a police box of the Phetkasem Police and destroyed the roof tiles. Police Sub-Lieutenant Wichai Nuchnart, who was inside, escaped unhurt.

No vehicles were directly hit by the poles, but the road obstruction caused traffic congestion.

Metropolitan Electricity Authority staff were clearing the area and replacing the poles.

Police Lieutenant Wirayut Suliamma of the Nong Khaem District Police Station said: 'The truck was transporting a large cement mixer owned by Italthai Trevi Co Ltd. It had just left a construction site and was driving through the intersection when it was caught on the cables.'

Truck driver Wirat Buaban, 53, said: 'I was driving from Samut Prakan and taking back the cement mixer. It was too tall, which is why it got hooked on the wires.'

He added that the incident has been reported to his company, and the damages will be shouldered by an insurance provider.

Thailand has one of the world's worst road safety records. Ministers have set the goal of reducing fatalities from 32.7 deaths per 100,000 people to 12 per 100,000 people by the year 2027.

However, a lack of road safety education in schools, cheap loans for cars, notoriously easy driving tests, police failures to enforce road laws as well as endemic corruption and chronic under-investment in infrastructure hamper the efforts.
