No vehicle can be legally driven without ___ for stopping.

The correct answer is that no vehicle can be legally driven without rear brake lights for stopping. Rear brake lights play a crucial role in vehicle safety by clearly signaling to drivers behind when the vehicle is decelerating or preparing to stop. This is vital for preventing rear-end collisions, as it allows other drivers ample warning to slow down or stop.

Brake lights must be functional at all times for a vehicle to be deemed roadworthy, as they communicate the driver's intentions to others on the road. While elements like turn signals, windshield wipers, and headlights are also important for safe vehicle operation and compliance with traffic laws, the specific requirement for indicating a stopping action falls squarely on the rear brake lights.
