Here's why they're there:
* Recovery: In case a car gets stuck or needs to be towed, the tow hook provides a secure point for attaching a tow cable or tow bar. It's designed to handle the stress of pulling the vehicle.
* Safety: Tow hooks are often located in a low, visible position so that tow truck operators can easily identify them.
* Regulations: In some countries, vehicles are required to have tow hooks as a safety feature.
Note: Not all cars have visible tow hooks. Some vehicles might have them hidden behind a panel or concealed in the bumper. Others might not have them at all, relying on other recovery methods.
