UN R12 — Protection against the steering mechanism in a collision
Review steering-system behaviour and related protection in a frontal collision.
Explore the scopeWhat does it cover?
UN R12 concerns vehicle approval for protecting the driver against the steering mechanism in a collision. In the defined M1 and certain N1 vehicles, this version also covers the high-voltage electric power train and components galvanically connected to its high-voltage bus. The assessment therefore extends beyond steering-wheel shape.
Who is it for?
Vehicle body, steering-system, passive-safety and crash-testing teams.
Which subjects are addressed?
- Steering-mechanism behaviour
- Occupant protection in a frontal collision
- High-voltage scope
- Vehicle type and test provisions
Common question
Is the scope limited to mechanical steering?
No. This version also names the high-voltage power train and related connected components. Consider vehicle category and technical configuration together.
