Review every question in this test with its correct answer and explanation.

1. Question 1At what maximum speed may a car overtake on a conventional road?

   
   • At 120 km/h.
   • At 100 km/h.
   • At 90 km/h.Correct answer

   Explanation

   To overtake on a conventional road, a car must respect the maximum speed limit of 90 km/h. This is because conventional roads have a specific speed limit to ensure the safety of all road users.

   • On motorways and highways, the maximum permitted speed is 120 km/h, but this is not the case for conventional roads, where the limit is lower.

   • Although some roads may have a limit of 100 km/h, this is not common and depends on the specific characteristics of the road.

   

   Therefore, when overtaking on a conventional road, a car must not exceed 90 km/h to comply with traffic regulations and ensure safe driving.

   Hint:

   The maximum speed allowed for passenger cars on conventional roads is 90 km/h, which is established to ensure safety and an adequate flow of traffic.

2. Question 2What is the maximum speed at which a 125 cc motorcycle may travel on a motorway?

   
   • At 90 km per hour.
   • At 80 km per hour.
   • At 120 km per hour.Correct answer

   Explanation

   125 cc motorcycles are considered motor vehicles and, therefore, are allowed to travel on motorways. The maximum speed allowed for this type of motorcycle on motorways is 120 km per hour.

   • Motorways are designed to allow higher speeds due to their infrastructure and safety conditions.
   • Other types of vehicles, such as mopeds or special vehicles, have different restrictions and cannot reach this speed on motorways.

   Therefore, a 125 cc motorcycle can travel at a maximum speed of 120 km per hour on a motorway.

   Hint:

   Motorcycles with a 125 cc engine can travel at a maximum speed of 120 km/h on highways, as they are classified as vehicles suitable for fast roads due to their ability to maintain higher speeds.

3. Question 3On this road through a built‑up area, what is the maximum permitted speed?

   
   • 50 km/h.
   • 40 km/h.Correct answer
   • 60 km/h.

   Explanation

   Maximum speed on crossings with a 40 km/h sign

   • General rule: in crossings, the maximum speed is 50 km/h.
   • If there is a vertical speed limit sign, that sign prevails over the general rule.
   • With a 40 sign, the maximum permitted speed is 40 km/h.

4. Question 4What must you do to warn that you are going to reduce your vehicle’s speed?

   
   • Press the brake pedal several times.Correct answer
   • Switch on the left turn indicator.
   • Switch on the position lights.

   Explanation

   To warn other drivers that you are going to decrease the speed of your vehicle, it is important to use the brake lights. These lights are activated when you press the brake pedal, indicating to the drivers behind you that you are slowing down.

   • The brake lights are bright red and are located at the rear of the vehicle.
   • It is mandatory for all vehicles, including cars, mopeds, trailers, and semi-trailers, to have these lights.
   • By pressing the brake pedal several times, the brake lights flash, which draws more attention from the drivers behind, ensuring they notice your intention to slow down.

   

   Therefore, the correct way to signal that you are going to decrease speed is to press the brake pedal several times to activate the brake lights.

   Hint:

   Pressing the brake pedal several times is an effective way to alert drivers behind you that you are going to reduce speed, as it activates the vehicle's brake lights, providing a clear and direct visual warning.

5. Question 5Are speed competitions allowed on public roads?

   
   • No, as a general rule.Correct answer
   • Only if a vehicle from the organization leads the race with a green flag.
   • Yes, always.

   Explanation

   Speed competitions on public roads are prohibited as a general rule. This is because driving at high speeds can be very dangerous. It increases the risk of making mistakes, as it is more difficult to react to unforeseen events and reduces the ability to see what is happening on the sides, a phenomenon known as tunnel vision. Additionally, driving fast for a long time can cause fatigue and aggression.

   Competitions are only allowed if the authorities authorize them and the necessary measures are taken to ensure safety. Participating in unauthorized races can result in the loss of points on the driving license. Therefore, the correct answer is that speed competitions on public roads are not allowed, except for authorized exceptions.

   Hint:

   Conducting speed competitions on public roads is generally prohibited to ensure the safety of all road users.

6. Question 6What is the maximum speed at which you may travel with a personal mobility vehicle?

   
   • 30 km/h
   • 6 km/h
   • 25 km/hCorrect answer

   Explanation

   Maximum speed of personal mobility vehicles

   A personal mobility vehicle (VMP) must always circulate between 6 km/h and 25 km/h. Its maximum legal speed is 25 km/h.

   Unlike pedal-assist bicycles, in PMVs movement depends only on the electric motor, so it is not allowed to exceed those 25 km/h, not even by “helping” with physical effort, since they do not have pedals.

   Hint:

   Personal mobility vehicles must always travel between 6 km/h and 25 km/h, so their legal maximum speed is 25 km/h.

7. Question 7Which of these speed concepts does not exist?

   
   • Advisory speed.
   • Vehicle speed.Correct answer
   • Excessive speed.

   Explanation

   In the context of driving, there are several types of speed that are important for road safety. However, the term "vehicular speed" is not a recognized concept in this field.

   • Excessive speed: This refers to when a vehicle is traveling at a speed higher than the maximum allowed on a road. For example, if the maximum allowed speed is 90 km/h and a vehicle is traveling at 100 km/h, it is exceeding the limit.

   • Advisory speed: Although not directly mentioned in the fragments, this term usually refers to a recommended speed under certain conditions, such as on dangerous curves or road sections with adverse conditions.

   Therefore, the term "vehicular speed" is not used to describe a specific type of speed in traffic regulations, making it nonexistent in this context.

   Hint:

   The term "vehicular speed" is not a formally recognized concept in traffic regulations, unlike other specific terms such as "excessive speed" or "advisory speed."

8. Question 8On this conventional road, what is the maximum permitted speed for a car?

   
   • 90 km/hour.Correct answer
   • 80 km/hour.
   • 120 km/hour.

   Explanation

   Speed limit on conventional roads for passenger cars

   • On conventional roads, the general limit for passenger cars is 90 km/h.
   • This limit applies on all conventional roads, regardless of the width of the hard shoulder.
   • It only changes if there is specific signage indicating another value.

9. Question 9What is the purpose of the speed limits set on roads?

   
   • To ensure safety and smooth traffic flowCorrect answer
   • To ensure safety only
   • To adapt driving to new vehicle technologies and the environment

   Explanation

   The speed limits have the main objective of ensuring safety and fluidity on the roads.

   • Safety: Speed limits are designed for vehicles to travel safely. For example, in urban areas, one must drive at less than 50 km/h to increase the chances of a pedestrian's survival in case of a collision. On roads and highways, limits are set to minimize the severity of accidents.

   • Fluidity: By maintaining an appropriate speed within the limits, a smoother and more comfortable flow of traffic is facilitated for all road users. This is especially important on highways and expressways, where a maximum speed of 120 km/h is allowed to ensure that traffic moves efficiently without compromising safety.

   • Adaptation to conditions: Additionally, speed should be adjusted to the weather conditions, the road, the vehicle, and the driver's state. This not only improves safety but also contributes to a smoother flow of traffic by allowing better vehicle control in unforeseen circumstances.

   

   In summary, speed limits not only aim to protect road users but also ensure that traffic develops in an orderly and efficient manner.

   Hint:

   Speed limits are set to ensure both safety and traffic flow, allowing for comfortable and safe driving that reduces the risk of accidents and facilitates mobility.

10. Question 10A truck with a maximum authorized mass of less than 3,500 kg, what is the maximum speed it may travel at on a dual carriageway (autovía)?

    
    • At 100 km/h.
    • At 120 km/h.
    • At 90 km/h.Correct answer

    Explanation

    For a truck weighing less than 3,500 kg of MMA traveling on a dual carriageway, the maximum permitted speed is 90 km/h. This is because trucks, along with other vehicles such as tractor-trailers and vans, have a specific speed limit on highways and dual carriageways.

    

    This restriction is applied to ensure road safety, as these vehicles are usually larger and heavier, which affects their braking and maneuverability. Therefore, the maximum speed of 90 km/h is appropriate for this type of vehicle on dual carriageways.

    Hint:

    The maximum speed allowed for trucks weighing less than 3,500 kg of MMA on highways is 90 km/h, according to current regulations.

11. Question 11When a driver is travelling at the appropriate speed...

    
    • it causes traffic to become slow and dangerous.
    • they are able to detect the intentions of other road users and react in time to avoid an accident.Correct answer
    • they annoy other drivers and may cause an accident.

    Explanation

    Traveling at an appropriate speed is crucial for road safety. This speed should not only be within legal limits but also adapt to weather conditions, the road, the vehicle, and the driver's state. By maintaining an appropriate speed, the driver has better control of the vehicle and can react in time to unforeseen events, significantly reducing the risk of accidents.

    

    Moreover, a constant and appropriate speed allows the driver to detect the intentions of other road users, such as lane changes or overtaking maneuvers, and react in a timely manner. This is part of preventive driving, which seeks to avoid dangerous situations by always maintaining a safe distance and avoiding being in the blind spot of other vehicles.

    On the other hand, maintaining an appropriate speed also contributes to efficient driving, as it avoids excessive fuel consumption and pollution. Constantly changing speed or making sudden stops and accelerations not only increases fuel consumption but can also tire the driver, affecting their reaction capacity.

    In summary, traveling at an appropriate speed allows the driver to be more attentive to their surroundings, react in time to potential dangers, and, in general, drive more safely and efficiently.

    Hint:

    Maintaining an appropriate speed allows the driver to observe and detect the intentions of other road users more effectively, which facilitates a timely reaction to avoid accidents.

    • At 110 kilometers per hour.
    • At 90 kilometers per hour.Correct answer

    Explanation

    Overtaking on conventional roads: no +20 km/h since 2022

    • On a conventional road, the maximum speed for cars is 90 km/h.
    • Since March 2022, the exception that allowed an increase of 20 km/h when overtaking has been eliminated.
    • Consequence: even when overtaking, you cannot exceed 90 km/h. If there is a sign with a lower limit, that lower limit must be respected.

18. Question 18What will be considered an abnormally low speed for a car on a conventional road without separation?

    
    • 45 km/h.
    • 60 km/h.
    • A speed below 45 km/h.Correct answer

    Explanation

    To understand why a speed lower than 45 km/h is considered abnormally low on a conventional road without separation, it is important to know the minimum speed limits established for different types of roads.

    • On conventional roads, where the maximum permitted speed for a car is 90 km/h, the minimum permitted speed is 45 km/h. This means that driving at a speed lower than 45 km/h is considered abnormally low and is prohibited, unless there are special circumstances such as heavy traffic, breakdowns, or road conditions that justify it.

    • The reason for establishing a minimum speed is to ensure that all vehicles circulate safely and efficiently. Driving too slowly can be dangerous, as it can cause accidents due to the speed difference with other vehicles.

    Therefore, on a conventional road without separation, any speed lower than 45 km/h is abnormally low and not allowed, except in exceptional situations.

    Hint:

    The minimum permitted speed for a passenger car on a conventional road without separation is 45 km/h, so any speed below this is considered abnormally low and may compromise road safety.

19. Question 19At speeds over 120 kilometers per hour on a motorway, the probability of surviving an accident...

    
    • Increases
    • Does not change
    • DecreasesCorrect answer

    Explanation

    Driving at more than 120 kilometers per hour on a motorway decreases the likelihood of surviving an accident. This is due to several reasons:

    • Speed limits: Speed limits are designed to ensure safety on the roads. On motorways and highways, it is established that it is safer to drive at less than 120 km/h. Exceeding this speed increases the risk of serious accidents.

    • Reaction to unforeseen events: At high speeds, it is more difficult to react quickly to unexpected situations, which increases the possibility of making fatal errors.

    • Tunnel vision: Driving fast reduces the ability to see what is happening on the sides, limiting peripheral vision and increasing the risk of accidents.

    • Fatigue and aggressiveness: Maintaining a high speed for a long time can cause fatigue and aggressiveness, negatively affecting driving ability.

    In summary, respecting speed limits is crucial to increase the chances of surviving an accident on motorways.

    Hint:

    At speeds exceeding 120 kilometers per hour, reaction capacity decreases and the risk of accidents increases, thereby reducing the likelihood of survival.

20. Question 20Driving at an inappropriate speed...

    
    • increases the risk of being involved in a traffic accident.Correct answer
    • does not affect the risk of being involved in an accident if the road is in good condition.
    • reduces the risk of being involved in a traffic accident.

    Explanation

    Driving at an inappropriate speed increases the risk of a traffic accident for several reasons:

    • Environmental conditions: Even if the speed is within the permitted limits, it may not be appropriate if the driver's conditions, weather, road conditions, or vehicle circumstances are not optimal. For example, driving at 70 km/h on an icy road can be dangerous because the vehicle may skid.

    

    • Reaction to unforeseen events: Driving at excessive speed makes it difficult to react quickly to unexpected situations, increasing the likelihood of making mistakes that can be fatal.

    • Limited vision: At high speeds, the ability to see what is happening on the sides is reduced, a phenomenon known as tunnel vision, which limits environmental perception and increases the risk of accidents.

    • Fatigue and aggressiveness: Driving fast for a long time can cause fatigue and aggressiveness, negatively affecting the ability to make safe decisions.

    • Misjudgment of speed: On roads in good condition, it is easy to underestimate the actual speed at which one is driving, which can lead to dangerous situations.

    For these reasons, it is crucial to adjust speed to environmental conditions to minimize the risk of accidents.

    Hint:

    Driving at an inappropriate speed increases the risk of accidents because it hinders the ability to react to unforeseen events and limits peripheral vision, increasing the likelihood of making fatal errors.
