These signs oblige you to keep distance from the car in front
Less than 70 meters to 900 meters
More than 70 meters to 900 meters✓Bonne réponse
70 meters after 900 meters.
Explication
The circular sign requires a gap greater than 70 metres, and the 900-metre extent plate states how long that requirement continues. It does not require a smaller gap or postpone the 70-metre rule until the end of the section.
