The **driver distraction warning system** is called **DDR-ADR**. This system is crucial for road safety, as it helps prevent accidents by alerting the driver when they are distracted or about to fall asleep.

- **DDR-ADR** uses **sensors** to detect if the driver is tired or distracted. These sensors gather information from the environment and the driver's behavior.
- When the system detects that the driver might be at risk of distraction or drowsiness, it issues an **alert**. This alert can be a light, a sound, or a vibration in the steering wheel, indicating to the driver that they should stop and rest to avoid an accident.

This system is different from other safety systems, such as the **Lane Departure Warning (LDW)**, which only warns when the vehicle drifts out of its lane, or the **Blind Spot Monitor (BSM)**, which alerts about vehicles in the blind spot. Both systems have specific functions, but they are not designed to detect driver distractions or drowsiness.
