1. Danger warning signs are intended to indicate to road users of the proximity and the nature of a danger difficult to be perceived in time, in order for them to comply with the rules of behaviour that they must follow in each case.

 

2. The distance between the sign and the beginning of the dangerous section may be indicated on a complementary panel to the designs included in the official catalogue of traffic signs.

 

3. If a hazard warning sign carries a supplementary panel indicating a length, it should be understood that it refers to the section of the road affected by the hazard, such as a succession of dangerous curves or a section of road in poor condition.

 

4. In the case of light signals, it may be permitted that the symbols appear in white on a dark non-luminous background.

 

5. The types of danger warning signs, with their respective nomenclature and meaning, are the following:

 

P-1 Intersection with priority. Danger due to the proximity of an intersection with a road, whose users must give way.

 

P-1 a. Intersection with priority on lane to the right. Danger due to the proximity of an intersection with a lane to the right, whose users must give way.

 

P-1 b. Intersection with priority over lane to the left. Danger due to the proximity of an intersection with a lane on the left, whose users must give way.

 

P-1 c. Intersection with priority over incorporation from the right. Danger due to the proximity of an incorporation on the right of a road, whose users must give way.

 

P-1 d. Intersection with priority over incorporation from the left. Danger due to the proximity of an incorporation on the left of a road, whose users must give way.

 

P-2. Intersection with priority on the right. Danger due to the proximity of an intersection where the general rule of priority applies.

P-9 a. Proximity of a level crossing, mobile bridge or pier (right side). Indicates, on the right side, the proximity of a signalized danger of a level crossing, a moveable bridge or a dock. This beacon is always accompanied by the signal P-5, P-7, P-8 or P-27.

 

P-9 b. Approach to a level crossing, moveable bridge or dock (right side). Indicates, on the right side, the approach to a level crossing, moveable bridge or dock, which is at least two-thirds of the distance between it and the corresponding danger warning signal.

 

P-9 c. Proximity of a level crossing, moveable bridge or dock (right side). Indicates, on the right side, the proximity of a level crossing, moveable bridge or pier, which is at least one third of the distance between it and the corresponding danger warning sign.

 

P-10 a. Proximity of a level crossing, moveable bridge or dock (left side). Indicates, on the left-hand side, the proximity of the signalized danger of a level crossing, a moveable bridge or a dock. This beacon is always accompanied by the signal P-5, P-7, P-8 or P-27.

 

P-10 b. Approach to a level crossing, moveable bridge or dock (left side). Indicates, on the left side, the approach to a level crossing, moveable bridge or dock, which is at least two-thirds of the distance between it and the corresponding danger warning signal.

 

P-10 c. Proximity of a level crossing, moveable bridge or dock (left side). Indicates, on the left side, the proximity of a level crossing, moveable bridge or dock, which is at least one third of the distance between it and the corresponding warning sign of danger.

 

P-11. Arrival at a level crossing without barriers. Danger due to the immediate presence of a level crossing without barriers.

 

P-11 a. Arrival at a level crossing without barriers of more than one railway. Danger due to the immediate presence of a level crossing without barriers with more than one railway.

 

P-12. Airport. Danger due to the proximity of a place where aircraft often fly at low altitudes on the road and which can cause unforeseen noise.

 

P-13 a. Dangerous curve to the right. Danger due to the proximity of a dangerous curve to the right.

 

P-13 b. Dangerous curve to the left. Danger due to the proximity of a dangerous curve to the left.

 

P-14 a. Dangerous curves, first to the right. Danger due to the proximity of a succession of curves close to each other; the first being to the right.

 

P-14 b. Dangerous curves, first to the left. Danger due to the proximity of a succession of curves close to each other; the first being to the left.

 

P-15. Uneven road. Danger due to the proximity of a shoulder or bump in the road or pavement in poor condition.

 

P-15 a. Projection. Danger due to the proximity of something sticking out on the road.

 

P-15 b. Dip. Danger due to the proximity of a dip in the road.

 

P-16 a. Downhill with steep slope. Danger due to the existence of a section of track with a steep descending slope. The figure indicates the slope in percentage.

 

P-16 b. Climb with steep slope. Danger due to the existence of a section of track with a steep upward slope. The figure indicates the slope in percentage.

 

P-17. Road narrowing. Danger due to the possibility of an area of the road in which the road narrows.

 

P 17 a. Narrowing of the road on the right. Danger due to the proximity of an area of the road where the road narrows on the right side.

 

P-17 b. Narrowing of the road on the left. Danger due to the proximity of an area of the road where the road narrows on the left side.

 

P-18. Works. Danger due to the proximity of a section of road works.

 

P-19. Slippery surface. Danger due to the proximity of an area of the road whose surface can be very slippery.
