Overview
- The R200 sign — a black horizontal bar on white inside a red circle — requires drivers to make a full stop before proceeding and the Dirección General de Tráfico says many people confuse it with a general 'no entry' sign leading to high error rates on theory tests.
- A yellow triangle with a black exclamation mark warns of a general, unspecified hazard that cannot be shown with a single pictogram and should prompt drivers to slow down and scan the road for the specific danger.
- The serrucho symbol signals an irregular road profile with successive rises and dips and drivers should reduce speed and avoid sudden maneuvers to protect vehicle stability and suspension.
- A white sign showing the serrucho with four diagonal lines marks the end of that warning, while the P.11-1 yellow sign for level crossings carries the legend 'Riesgo de atascamiento' to warn long vehicles that they may become stuck on steep or angled crossings.
- Experts and official guidance consistently advise easing off the accelerator, increasing following distance and avoiding abrupt steering or braking because differing colors, legends and regional sign systems can produce dangerous misreadings and legal exposure.
