Dozens of wild monkeys climbed over a pickup truck stuck in traffic.

Footage shows the troop clambering on the metal bars of the cage on the back of the vehicle and picking up the grass to eat in Lopburi province, Thailand.

The primates came from a nearby park's open fields and approached the truck as it passed by their habitat.

When traffic eased, they soon left the vehicle one by one, and the truck started moving along.

Kanalayanee, who was inside the truck, said: 'The little monkeys searched our car for food.'

Lopburi has become a popular tourist destination because of its large population of monkeys. The monkeys are mostly long-tailed macaques, and they can be found all over the city, from the temples to the streets.

However, they can also be aggressive, and they have been known to steal food and belongings.
