The family of more than 50 jumbos emerged from the jungle and stomped across the highway in Chachoengsao province on April 9.
Spectacular footage shows how dozens of locals gathered on either side of the road to watch the placid creatures.
Several police officers also arrived to ensure the elephants made it safely to the neighbouring area of jungle.
Wildlife rangers had been tracking the elephants through the wilderness during the day then quickly blocked off the road to prevent any accidents.
