Señales de advertencia — Significado y Ejemplos (2026)

IncorrectoRespuesta correcta: A — Hay un peligro o un cambio en las condiciones de la vía más adelante

Los rombos amarillos son señales de advertencia general: una curva, una incorporación, una cuesta u otro peligro más adelante. Te aconsejan reducir la velocidad, pero por sí solas no imponen un límite legal.

Los rombos naranjas —no los amarillos— indican zona de obras. Misma forma, otro color, otro significado.

IncorrectoRespuesta correcta: A — The road changes direction here, so follow the curve and stay in your lane

Chevrons are placed in a series through a change of alignment so at least one is always in view. Together they show how sharp the bend is and where the road goes at night, when your headlights cannot reach around it.

Reading a chevron as an instruction to change lanes. It describes the alignment of the road, not a movement you are being told to make.

IncorrectoRespuesta correcta: C — A stop sign is ahead, so begin slowing in order to stop at it

A warning sign describes what is coming, not what happens where it stands. This one is used where the stop sign itself is hidden by a curve, a crest or trees, giving you the distance you need to stop under control.

Stopping at the warning sign itself, which surprises the driver behind. The stop is made at the stop line further on.

IncorrectoRespuesta correcta: A — A yield sign ahead, where you slow and give way to the traffic that has the right of way

It warns of an upcoming yield point. Knowing early lets you shed speed gradually instead of braking hard at the line, which is what makes it possible to actually give way rather than force your way in.

Reading yield as slow down a little. If there is no safe gap, yielding means coming to a stop.

IncorrectoRespuesta correcta: C — A signalized intersection is ahead and you should slow down ready to stop

This warning is posted where a signal cannot be seen far enough ahead — over a crest, round a curve, or on a fast road — so that you are already slowing before the red comes into view.

Because the symbol contains a red lens, drivers read the sign as reporting the signal's current state. It reports only that a signal exists ahead; the light itself may be any colour when you get there.

IncorrectoRespuesta correcta: D — A traffic signal ahead cannot be seen in time from this approach

Signal Ahead is used where a hill, curve or trees hide the signal until a driver is too close to stop comfortably. The sign restores the warning distance the sight line took away, so cross the crest already prepared for red.

Assuming that not seeing a red light yet means there is time. On a blind approach the light may have been red for a while before it comes into view.

IncorrectoRespuesta correcta: B — Tráfico de otra vía se incorporará a la tuya y ambos deben adaptarse

Una incorporación significa que dos flujos se convierten en uno. Ningún conductor tiene preferencia automática; se espera que ambos ajusten velocidad y posición.

Muchos conductores creen que el que se incorpora siempre debe ceder. La señal advierte a ambas vías; cooperar funciona mejor que imponerse.

IncorrectoRespuesta correcta: B — Another roadway joins yours ahead and the two streams continue in the same lane

A merge warning means two streams of traffic come together into one path, so a vehicle you cannot yet see may be arriving beside you. Adjusting speed and opening a gap early is what keeps the blend from becoming a conflict.

Confusing a merge with an added lane. In a merge there is no extra lane waiting, so one driver has to make room and the other has to take it.

IncorrectoRespuesta correcta: C — El tráfico entra en su propio carril nuevo, así que no hace falta incorporarse

Un carril adicional significa que la vía que se une recibe su propio carril. Nadie tiene que ceder ni cambiarse, y por eso una incorporación innecesaria aquí genera conflicto.

Quien trata un carril adicional como una incorporación frena o se desvía por un tráfico que nunca iba a entrar en su carril.

IncorrectoRespuesta correcta: C — The joining road becomes an extra lane, so neither stream has to give up its lane position

With an added lane the entering roadway continues as a lane of its own instead of feeding into yours, so vehicles join without anyone having to yield. Keep watching it anyway, because an added lane often ends further along and then a real merge does happen.

Swinging left to make room as if it were a merge, which puts you into a lane you never checked. With an added lane you can simply hold your position.

IncorrectoRespuesta correcta: D — La vía se divide en dos calzadas de sentido único separadas por una mediana

La calzada se separa y una mediana divide los sentidos. Debes mantenerte a la derecha del divisor: cruzarlo o entrar por el lado equivocado es circular de frente contra el tráfico.

Esta señal y la de FIN DE CALZADA DIVIDIDA se parecen a velocidad. Una significa que empieza la mediana; la otra, que el tráfico contrario está a punto de volver a tu lado.

IncorrectoRespuesta correcta: A — El tráfico contrario vuelve a la misma calzada que tú

La mediana termina y la vía pasa a ser de doble sentido. El tráfico del que estabas separado ahora viene hacia ti por el carril contiguo.

Como una calzada dividida se siente como una autopista, los conductores mantienen los hábitos de autopista —incluido derivar hacia la izquierda— justo hacia el tráfico contrario.
