# Driver Responsibility & Level 2 ADAS
|
||
|
||
!!! danger "You Are Always Responsible"
|
||
sunnypilot is **NOT** a self-driving system. You are legally and morally responsible for the vehicle at all times. No feature in sunnypilot removes or reduces your obligation to drive safely.
|
||
|
||
## What is Level 2 ADAS
|
||
|
||
sunnypilot is classified as a **Level 2 Advanced Driver Assistance System (ADAS)** per the SAE J3016 standard for driving automation. The SAE levels define increasing degrees of automation:
|
||
|
||
| SAE Level | Name | Driver Role |
|
||
|-----------|------|-------------|
|
||
| 0 | No Automation | Driver performs all tasks |
|
||
| 1 | Driver Assistance | System controls steering OR speed, not both |
|
||
| **2** | **Partial Automation** | **System controls steering AND speed; driver must supervise** |
|
||
| 3 | Conditional Automation | System handles driving in limited scenarios; driver must be ready |
|
||
| 4–5 | High/Full Automation | System handles all driving tasks in defined conditions |
|
||
|
||
sunnypilot operates at **Level 2** only. It can control steering and speed simultaneously, but the human driver must remain fully engaged at all times.
|
||
|
||
## What This Means
|
||
|
||
At Level 2, the system provides assistance — not autonomy. Specifically:
|
||
|
||
- The system **can** control steering, acceleration, and braking simultaneously
|
||
- The system **cannot** handle unexpected situations, edge cases, or complex scenarios reliably
|
||
- The **driver** is the fallback for every situation the system cannot handle
|
||
- The **driver** bears full legal responsibility for the vehicle's operation
|
||
|
||
## Driver Obligations
|
||
|
||
As the operator of a Level 2 ADAS vehicle, you must:
|
||
|
||
- **Keep your hands on the steering wheel** at all times
|
||
- **Keep your eyes on the road** and maintain situational awareness
|
||
- **Be ready to intervene immediately** — the system can disengage or behave unexpectedly without warning
|
||
- **Follow all traffic laws** — the system does not replace your judgment or legal obligations
|
||
- **Never rely on the system** as a substitute for attentive driving
|
||
|
||
## NHTSA Guidance
|
||
|
||
The National Highway Traffic Safety Administration (NHTSA) classifies Level 2 systems as requiring **full driver engagement**. NHTSA's position is clear:
|
||
|
||
- Level 2 systems are **driver support features**, not automated driving systems
|
||
- The driver must be able to perform the complete driving task at all times
|
||
- Manufacturers and operators share responsibility for safe use of these systems
|
||
