Preventive and Efficient Driving: Safety and Savings at the Wheel

🔍 1. Preventive driving techniques

Preventive driving is a technique that allows you to anticipate risks, keeping control of the vehicle at all times. It is based on three key principles:

  • 👀 Vision: observe the surroundings broadly and constantly.
  • Anticipation: foresee possible dangers before they occur.
  • 📏 Space: maintain proper distances in front, behind, and to the sides.

👁️ Vision techniques

  • 🔭 Look as far ahead as possible, especially at higher speeds.
  • 👂 Check the sides frequently.
  • 🪞 Use mirrors and turn your head to cover blind spots.

⚠️ Anticipation

  • 🧠 Drive attentively and with healthy caution.
  • 🚦 Adapt your speed to the circumstances.
  • 📢 Signal your maneuvers clearly and use your lights correctly.

📐 Space management

You should increase the following distance when:

  • 🪶 The vehicle is loaded.
  • 🌧️ Weather conditions are adverse.
  • 😴 The driver is tired or unwell.
  • 🚗 Another vehicle is following too closely.

In traffic jams, if you’re the last in line, switch on the hazard lights and keep an eye on the mirror 🚨.

💨 2. Efficient driving techniques

Applying efficient driving techniques helps the environment 🌍, reduces costs 💰, and improves safety 🛡️.

🔥 Pollution and emissions

  • 🌫️ CO₂: responsible for the greenhouse effect.
  • ☣️ Other polluting gases: CO, HC, NOx.

🌟 Benefits

  • ✅ Lower fuel consumption.
  • 📉 Reduced maintenance.
  • 🎧 Less noise pollution.
  • ♻️ Smoother, more comfortable driving.

⚙️ Making the most of energy

Only about 30% of the fuel’s energy reaches the wheels 🚗💨. Losses are due to:

  • 🔥 Thermal losses (exhaust and cooling systems).
  • ⚙️ Mechanical losses (friction and transmission).

🌪️ Forces resisting motion

  • 🛞 Rolling resistance (tires).
  • 🏔️ Gradient (gravity).
  • 💨 Aerodynamics (shape, air, speed).
  • ⏱️ Acceleration (mass and change in speed).

🚦 Practical tips for efficient driving

🚗 When setting off

  • 🔑 Start without pressing the accelerator.
  • 🕒 Wait a few seconds for the engine to lubricate and for the air tanks to pressurize.
  • ⚙️ Use the appropriate gear from the start and release the clutch before accelerating.

🔁 When shifting gears

  • 📈 Use the tachometer: shift in the green band.
  • 🛑 Avoid over-revving the engine.
  • ⏩ Skip gears when possible to reach higher gears sooner.

🚘 While driving

  • 🧭 Maintain a steady speed.
  • 🥾 Avoid unnecessary hard acceleration and braking.
  • 🔃 Use higher gears and press the accelerator only up to about 3/4 of its travel.

🛑 When decelerating or downshifting

  • ⚠️ Lift off the accelerator and don’t press the clutch.
  • ⛰️ Take advantage of inertia, especially downhill.
  • 🔧 Use engine braking and retarders before the service (foot) brake.

💡 Other tips

  • ⛽ Switch off the engine if you will be stopped for more than 2 minutes.
  • 🚫 Do not rev the engine before switching it off.
  • 📦 Don’t overload the vehicle unnecessarily.
  • 🧰 Keep the vehicle up to date and well serviced.
  • 🌬️ Set the air conditioning to 20–23ºC.
  • 🗺️ Plan your route and avoid traffic jams or slow roads.

🧪 Active particulate filter

This device reduces the emission of particulate matter in diesel vehicles:

  • ⛔ Avoid short trips.
  • 🔄 Don’t switch off the engine during regeneration.
  • 🛢️ Use oil suitable for engines with a particulate filter.
  • 📆 Follow the manufacturer’s maintenance schedule.

🚫 Prohibitions related to pollution

  • 🚫 Damaged mufflers or open exhausts.
  • 🚭 Emission of dense smoke or harmful gases.
  • 📢 Unnecessary or excessive noise.
  • 💥 High electromagnetic interference.

In these cases, officers may immobilize the vehicle and issue penalties ⚠️.
