Circular a velocidad anormalmente reducida, ¿puede causar accidentes?
Can driving at an abnormally low speed cause accidents?
- ASí.Yes.
- BNo, porque se va más despacio y es más seguro.No, because you are going more slowly and it is safer.
- CSolo en autopistas y autovías.Only on motorways (autopistas) and dual carriageways (autovías).
Explanation
An abnormally low speed is a speed below the minimum allowed. Driving at such a speed disrupts the normal flow of traffic and can therefore cause accidents.
Nº 802

Nº 804
¿Cuál es la velocidad máxima permitida para un coche en una vía urbana con plataforma única de calzada y acera?
What is the maximum speed allowed for a car on an urban road where the carriageway and pavement share a single level (single-level street)?
- A45 km/h.45 km/h.
- B50 km/h.50 km/h.
- C20 km/h.20 km/h.
Explanation
On urban roads where the carriageway and pavement form a single surface, with no difference in level between them, the general limit is 20 km/h (Article 50.1.a of the General Traffic Regulations). With a single lane in each direction it would be 30 km/h, and with two or more, 50 km/h.
Nº 805
Un cuadriciclo ligero, ¿a qué velocidad máxima puede circular fuera de poblado?
What is the maximum speed of a light quadricycle outside built-up areas?
- AA 70 km/h.70 km/h.
- BA 45 km/h.45 km/h.
- CA 50 km/h.50 km/h.
Explanation
For three-wheeled vehicles and quadricycles that are NOT light, the limit is 70 km/h on any paved road outside built-up areas where they are allowed. A light quadricycle is considered a four-wheeled moped. Mopeds are built so that they cannot go faster than 45 km/h, so that is the limit they must keep to.
Nº 806
En una carretera convencional de doble sentido, ¿a qué velocidad máxima le está permitido adelantar con su turismo a un camión?
On a conventional two-way road, what is the maximum speed at which you may overtake a lorry in your car?
- AA 120 kilómetros por hora.120 kilometres per hour.
- BA 110 kilómetros por hora.110 kilometres per hour.
- CA 90 kilómetros por hora.90 kilometres per hour.
Explanation
The 20 km/h margin for overtaking on conventional roads was abolished by Law 18/2021, with effect from 21 March 2022. A car may not exceed its general limit of 90 km/h on these roads, not even while overtaking.
Nº 807
Circulando por una vía sin pavimentar, ¿cuál será la velocidad máxima permitida para una motocicleta?
Riding on an unpaved road, what is the maximum speed allowed for a motorcycle?
- A30 km/h.30 km/h.
- B50 km/h.50 km/h.
- C80 km/h.80 km/h.

You are driving at 70 km/h. Which lane must you use?
- APor el carril central.The centre lane.
- BPor el carril derecho.The right-hand lane.
- CPor el carril que mejor convenga a su destino.Whichever lane suits your destination best.
Explanation
Outside built-up areas, on carriageways with more than one lane in each direction, you normally drive in the right-hand lane and use the others when traffic or road conditions make it advisable (Article 31.1 of the General Traffic Regulations). The figures on the sign are maximums, not minimums.
Nº 810
¿Qué distancia lateral deben dejar las motocicletas al cruzarse con otros vehículos que circulen en sentido contrario?
What lateral distance must motorcycles leave when passing vehicles coming in the opposite direction?
- A1,5 metros como máximo.No more than 1.5 metres.
- B1,5 metros como mínimo en cualquier caso.At least 1.5 metres in all cases.
- CUna separación lateral suficiente para que el cruce pueda realizarse con seguridad y sin riesgo.Enough lateral space for them to pass each other safely and without risk.
Explanation
Motorcycles must leave enough lateral space when passing vehicles coming in the opposite direction, for the safety of both. This is because motorcycles, given their size and stability, need more space to avoid collisions. The rules say that the gap must be sufficient, not a fixed figure, which is why the correct option is the one that mentions enough lateral space for them to pass each other safely and without danger.
Nº 811
¿Cuál es la velocidad anormalmente reducida en autovía?
What is an abnormally low speed on a dual carriageway (autovía)?
- ALa inferior a 80 km/h.Below 80 km/h.
- Bla inferior a 60 km/h.Below 60 km/h.
- Cla inferior a 50 km/h.Below 50 km/h.

Nº 815
En una carretera convencional, un camión quiere adelantar a otro vehículo, ¿a qué velocidad máxima puede hacerlo?
On a conventional road, a lorry wants to overtake another vehicle. What is the maximum speed at which it may do so?
- AA 100 Km/h.100 km/h.
- BA 120 Km/h.120 km/h.
- CA 80 Km/h.80 km/h.
Explanation
Under Article 48.1.a) of the General Traffic Regulations, a lorry has a maximum of 80 km/h on a conventional road and may not exceed it while overtaking. The 20 km/h margin for overtaking was abolished with effect from 21 March 2022.
Nº 816
Si su vehículo no puede alcanzar 60 km/h, ¿por qué vías no podrá circular?
If your vehicle cannot reach 60 km/h, on which roads may it not be driven?
- APor vías urbanas.On urban roads.
- BPor carreteras interurbanas.On non-urban roads.
- CPor autopistas y autovías.On motorways (autopistas) and dual carriageways (autovías).
Explanation
Article 49.1 of the General Traffic Regulations forbids driving motor vehicles at less than 60 km/h on motorways (autopistas) and dual carriageways (autovías). On other roads the minimum is half the general limit for each vehicle, so a vehicle that cannot reach 60 km/h may be driven on them.
Nº 817
¿A qué velocidad podrá circular un conductor novel por esta carretera convencional?
At what speed may a novice driver drive on this conventional road?
- A80 km/h, más 20 km/h para adelantar.80 km/h, plus 20 km/h for overtaking.
- B90 km/h.90 km/h.
- C100 km/h.100 km/h.
Explanation
The maximum speed for a novice driver is the same as for other drivers, although they must display a plate with the letter L in a visible place. The maximum speed allowed on conventional roads is 90 km/h.
Nº 818
Circulando por un mercado o parte de la vía frecuentada por peatones, especialmente niños o ancianos, ¿qué haremos?
When driving through a market or a part of the road used by many pedestrians, especially children or elderly people, what will we do?
- AReducir la velocidad, incluso llegando a detenerme.Reduce speed, even stopping if necessary.
- BAdoptaré las medidas necesarias para su seguridad, sin tener que moderar obligatoriamente la velocidad.Take the necessary steps for their safety, without necessarily having to reduce speed.
- CReducir la velocidad, sin necesidad de detenerme.Reduce speed, without needing to stop.
Explanation
If there are pedestrians on the part of the road we are using, we must reduce speed, even to the point of stopping, although the pedestrians do not have priority. Pedestrians are fragile and vulnerable road users who would suffer serious injury if hit, so great care is needed to prevent this.
Nº 819
Conducir a una velocidad adecuada nos permite...
Driving at a suitable speed allows us to...
- AEvitar atascos.avoid traffic jams.
- BAhorrar el mantenimiento preventivo del vehículo.save on preventive maintenance of the vehicle.
- CControlar el vehículo ante algún suceso imprevisto.control the vehicle if something unexpected happens.
Explanation
The traffic authority states that a vehicle is travelling at a suitable speed when that speed allows us to control the vehicle in the face of any obstacle or unexpected event. This suitable speed is not based only on the limits shown by signs; the conditions of the road, of our vehicle and our own condition must also be taken into account. So we drive at a suitable speed when we adapt it to the conditions of the moment: driver, vehicle and environment.
Nº 820
Circula con un turismo por autopista, ¿qué velocidad se considera anormalmente reducida?
You are driving a car on a motorway (autopista). What speed is considered abnormally low?
- ALa menor de 50 km/h.Below 50 km/h.
- BLa menor de 60 km/h.Below 60 km/h.
- CLa menor de 70 km/h.Below 70 km/h.
Explanation
An abnormally low speed means driving below the minimum speed allowed on a road. The minimum speed on motorways (autopistas) and dual carriageways (autovías) is 60 km/h.
Nº 821
La distancia de frenado con la calzada helada será...
On an icy carriageway, braking distance will be...
- AHasta 2 veces mayor que si está seca.up to 2 times longer than when it is dry.
- BHasta 10 veces mayor que si está seca.up to 10 times longer than when it is dry.
- CEl estado de la calzada no influye en la distancia de frenado.The condition of the carriageway does not affect braking distance.
Explanation
Braking distance is the distance the vehicle travels from when the driver applies the brake until the vehicle stops. This distance may vary depending on the following factors: - The speed you are driving at. - The condition of the vehicle's tyres, suspension and brakes. - The vehicle's load. - The condition of the road surface. - The weather conditions on the road. Braking distance can double when the carriageway is wet and be up to 10 times longer on ice or snow.
Nº 822
¿Cuándo hay que aumentar la distancia de seguridad?
When must you increase your safe distance?
- ACuando aumenta la velocidad.When your speed increases.
- BCuando voy a adelantar.When I am going to overtake.
- CCuando disminuye la velocidad de los vehículos.When the speed of vehicles decreases.
Explanation
Article 54.1 of the General Traffic Regulations requires you to leave enough space behind the vehicle in front to stop without hitting it, taking speed into account in particular. As stopping distance increases with speed, the faster you go, the bigger the gap must be.
Nº 823
En determinadas circunstancias, un turismo, ¿puede superar para adelantar la velocidad máxima fijada para el tipo de vía por la que circule?
In certain circumstances, may a car exceed the maximum speed set for the type of road it is on in order to overtake?

Nº 826
Si un vehículo circula a velocidad inferior al límite máximo permitido, ¿puede suponer un riesgo?
If a vehicle is travelling below the maximum speed limit, can it still be a risk?
- ANo, si la velocidad es inferior a la máxima no puede haber riesgo.No, if the speed is below the maximum there can be no risk.
- BNo, el riesgo únicamente se produce al circular a una velocidad superior a la máxima.No, risk only arises when driving above the maximum speed.
- CSí.Yes.
Explanation
Even when driving within the speed limits, problem situations can arise that mean you must slow down to suit the conditions, for example rain, fog or snow on the carriageway.
Nº 827
Por esta vía, ¿circularemos correctamente a 60 km/h utilizando el arcén?
On this road, are we driving correctly on the hard shoulder at 60 km/h?
- ASí.Yes.
- BNo.No.
- CSí, si el arcén es transitable y suficiente.Yes, if the hard shoulder is passable and wide enough.
Explanation
To use the hard shoulder we must be driving at an abnormally low speed, that is, below 60 km/h, because of an emergency, and also be seriously disrupting traffic.
Nº 828
¿Cuál será la velocidad máxima a la que le está permitido circular por una autopista si conduce una autocaravana de MMA inferior a 3.500 kg?

Driving at a higher speed will increase...
- AEl tiempo de reacción del conductor.The driver's reaction time.
- BLa capacidad del conductor.The driver's ability.
- CLa distancia de reacción.The reaction distance.
Explanation
At a higher speed the driver's reaction time does not change, but their ability to react and anticipate does decrease, so the reaction distance increases; that is, the number of metres travelled during the reaction time increases. The higher the speed, the more metres travelled in the same time.
Nº 842
En esta vía, ¿a qué velocidad mínima está permitido circular con un turismo?
On this road, what is the minimum speed permitted for a car?
- AA 45 km/h.45 km/h.
- BA 50 km/h.50 km/h.

Which vehicles does a 60 km/h maximum speed road marking apply to?
- AA todos los que circulen por la vía.All vehicles on the road.
- BSolamente a los que circulen por el carril en el que se encuentra la marca.Only those in the lane where the marking is.
- CSolamente a los turismos y motocicletas que circulen por la vía.Only cars and motorcycles on the road.
Explanation
A speed limit road marking only applies to vehicles in the lane where the marking is, as long as the lanes are marked; if they are not, it applies to the whole carriageway.
Nº 844
Dentro de poblado, ¿por qué es importante no superar los 50 km/h?
In built-up areas, why is it important not to exceed 50 km/h?
- APara no ser multado.So as not to be fined.
- BPorque lo dice la norma general.Because the general rule says so.
- CPorque en caso de atropello de un peatón, la probabilidad de lesiones graves es menor.Because if a pedestrian is hit, the likelihood of serious injury is lower.
Explanation
The higher the speed at the moment a pedestrian is hit, the more serious the injuries and the lower their chances of survival. Moreover, in built-up areas 50 km/h is the general limit only on roads with two or more lanes in each direction; with a single lane in each direction it is 30 km/h (Article 50.1 of the RGC).
Nº 845
Si el vehículo que conduce no puede desarrollar la velocidad de 60 kilómetros por hora, ¿por qué vías no podrá circular?
If the vehicle you are driving cannot reach a speed of 60 km/h, which roads may you not use?
- APor vías urbanas.Urban roads.
- BPor todas las vías interurbanas.All roads outside built-up areas.
- CPor autopistas y autovías.Motorways (autopistas) and dual carriageways (autovías).
Explanation
You must not obstruct the normal progress of other vehicles by driving at an abnormally low speed without good reason. For this purpose, motor vehicles may not be driven on motorways (autopistas) and dual carriageways (autovías) at less than 60 km/h, or on other roads at less than half the general speed limit set for each category of vehicle on that road, even if there is no other traffic.
Nº 846
Vas más rápido de la velocidad máxima permitida, ¿cómo estás circulando?
You are going faster than the maximum permitted speed. How are you driving?
- AA una velocidad excesiva.At an excessive speed.
- BA una velocidad adecuada.At a suitable speed.
- CA una velocidad moderada.At a moderate speed.
Explanation
Exceeding the maximum permitted speed is driving at an excessive speed. An unsuitable speed, on the other hand, is one that does not match the circumstances, such as rain, fog or heavy traffic, even if it does not exceed the road's limit.
Nº 847
Dentro de los límites máximos de velocidad, ¿puede ser que circulemos a velocidad inadecuada?
Is it possible to be driving at an inappropriate speed while within the maximum speed limits?
