8. Crossing animals
An animals-crossing warning indicates a place or road section where wild animals, livestock or ridden animals may enter or cross the road. Animals may appear suddenly, move unpredictably or be difficult to see in darkness, vegetation or poor weather.
Drivers should reduce speed, scan both sides of the road and remain prepared to stop. The warning sign does not itself give animals priority or impose a numerical speed limit, but drivers must avoid frightening, endangering or colliding with them.

Which animals might drivers encounter on roads in Thailand?
Animal warnings identify a risk of animals on or beside the road. Watch for actual movement and reduce speed enough to respond safely. A warning does not guarantee that animals stay within a short signed section or establish a new numerical speed limit.
Does an animal-crossing warning sign in Thailand set a new speed limit?
A warning of animals is not, by itself, a numerical speed-limit sign. Continue to obey the applicable speed limit, but slow down whenever animals could enter the road or visibility is poor. A separate regulatory speed sign must also be obeyed.

What should you do if an animal enters the road in Thailand?
Ease off the accelerator, assess the traffic behind and brake smoothly if necessary. Avoid abrupt swerving into opposing traffic or off the road. Give farm animals and ridden animals room, avoid frightening them with unnecessary horn use, and be alert for more animals following.
