Minimum mandatory distance between vehicles

Sign **R-300 (minimum separation)** **prohibits driving** if you do not keep with the vehicle ahead a **distance equal to or greater** than that indicated on the sign.

- This requirement applies **at all times**, **except** when you are going to make an **overtaking manoeuvre**.
- If the sign **does not show any figure**, remember that you must maintain at least the **safety distance** established by the Regulations, sufficient to **stop the vehicle in time** without colliding with the one in front.

In summary, this sign ensures that there is a **mandatory safety gap** between vehicles, preventing you from driving too close to the vehicle ahead.
