Speed and Road Safety: Limits, Rules, and Consequences | DGT

Driving at an appropriate speed is key to road safety. In this article you’ll learn all about legal limits, the appropriate speed according to conditions, and the consequences of speeding. ⚖️🚦

1️⃣ Maximum and minimum speeds for mopeds 🛵

  • 🔹 General maximum: 45 km/h
  • 🔹 With trailer: 40.5 km/h (10% less)
  • 🔹 In residential areas: 20 km/h

📊 Table of maximum speeds on interurban roads

Type of roadMaximum speed
Motorways and expressways120 km/h
Conventional roads with a physical median100 km/h
Other conventional roads90 km/h
Urban roads30 km/h or 50 km/h depending on signage

2️⃣ Appropriate speed according to circumstances 🧠🌧️

The driver must adapt their speed considering:

  • 👤 Physical and mental state
  • 🚗 Vehicle and load condition
  • 🛣️ Road condition
  • 🌦️ Weather and visibility
  • 🚦 Traffic and obstacles

3️⃣ Mandatory speed reduction ⛔

Speed must be reduced when:

  • 🚸 There are pedestrians, children, or animals
  • 🏫 Near schools, markets, or bus stops
  • 🏍️ Approaching cyclists
  • 🌫️ Visibility is reduced: fog, rain, snow
  • ⚠️ Roundabouts, level crossings, junctions, or narrow sections

4️⃣ Consequences of speeding 💥

  • 👁️‍🗨️ Tunnel effect: reduced field of vision
  • 🧠 Slower reaction to hazards
  • 🤕 Greater severity of crashes
  • 🚧 Fatigue, stress, and a false sense of speed

5️⃣ Precautions when slowing down ⚠️

Braking should be done safely, using:

  • 💡 Flashing brake lights
  • ✋ Hand signal (arm moving up and down)

6️⃣ Speed competitions 🚫🏁

Prohibited on public roads unless specially authorized. The area must be properly arranged.

7️⃣ Stopping distance 🛑

7.1 Reaction time ⏱️

Average: 0.75 s. Increases with age, fatigue, alcohol, medication, etc.

7.2 Reaction distance 🛣️

Depends on speed and reaction time. The higher the speed, the greater the distance.

7.3 Braking distance 🛑

Factors:

  • 🔹 Vehicle speed
  • 🔹 Vehicle mass and load
  • 🔹 Driver skill
  • 🔹 Condition of brakes, tyres, and road surface

7.4 Weather ❄️🌧️

  • 💧 Rain: 2× braking distance
  • ❄️ Snow or ice: up to 10× braking distance

7.5 Total stopping distance 📏

It is the sum of:

  • 🔹 Reaction distance
  • ➕ Braking distance

⚠️ Remember: speed saves time, but if mismanaged it can cost lives. Drive responsibly! 🛑
