Content focused exclusively on:

  • lighting systems

  • rules for use of lights

  • transport of goods (cargo)

  • transport of persons

  • techniques and rules frequently appearing in the DGT exam


1. VEHICLE LIGHTING

Mandatory use of lights

Lights must be used to:

  • see

  • be seen

  • increase safety


Position lights

They indicate:

  • presence of the vehicle.

They are used:

  • in low visibility conditions

  • when parking on certain roads.


Dipped beam (low beam)

Used:

  • at night

  • in tunnels

  • with rain or fog

  • when there is insufficient visibility

๐Ÿ’ก Frequently asked:

Dipped beam is the most used light in normal nighttime driving.

Used:

  • on interurban roads without lighting

Must be switched to dipped beam when:

  • there are vehicles ahead

  • vehicles are approaching from the opposite direction

๐Ÿ’ก Typical DGT mistake:

Do not dazzle other drivers.


Front fog light

Used:

  • in fog

  • heavy rain

  • snow

It helps to:

  • improve close-range visibility


Rear fog light

Mandatory or recommended use:

  • dense fog

  • very heavy rain

๐Ÿ’ก Important:

It is very powerful and can dazzle if misused.


Turn signals

They are used to:

  • indicate maneuvers

  • turns

  • overtaking

  • lane changes

๐Ÿ’ก DGT rule:

Always signal before maneuvering.


Hazard lights

Used when:

  • there is danger

  • vehicle stopped due to breakdown


Lighting in tunnels

Mandatory to use:

  • dipped beam


Incorrect use of lights

It is prohibited to:

  • dazzle other drivers

  • use high beam unnecessarily


2. CARGO TRANSPORT (GOODS)

General principles

The cargo must be transported:

  • safely

  • properly secured

  • without danger to traffic


Securing the cargo

The following must be avoided:

  • shifting

  • falling

  • excessive noise or vibration

๐Ÿ’ก Frequently asked:

Poorly secured cargo can cause an accident or penalty.


Cargo distribution

It must be placed:

  • as low as possible

  • balanced

Avoid:

  • overloading on one side


Protruding cargo

It may protrude:

  • provided it is properly signaled

It must be signaled:

  • when it protrudes from the rear


Weight limit

You must not exceed:

  • the maximum authorized mass (MMA)

๐Ÿ’ก Typical mistake:

Driving overweight is a serious infraction.


Driver visibility

The cargo must not:

  • obstruct vision

  • interfere with driving


Transport of dangerous goods

Requires:

  • specific regulations

  • special signaling

  • authorization


3. TRANSPORT OF PERSONS

General rule

  • standing in unauthorized vehicles


Transport in goods vehicles

As a general rule:

  • people cannot be transported in the cargo area

Except:

  • authorized vehicles or specific conditions


Buses

Key rules:

  • seat count control

  • mandatory use of seat belt when available


4. SAFETY TECHNIQUES

Safe driving with cargo

Consider:

  • greater vehicle inertia

  • greater braking distance


Braking with cargo

The vehicle needs:

  • more distance to stop


Curves with cargo

Risk:

  • shifting of the cargo

You must reduce:

  • speed


5. COMMON MISTAKES IN THE EXAM

  • confusing the use of high and low beams

  • not using fog lights correctly

  • forgetting that cargo must be secured

  • exceeding authorized seats

  • transporting people in cargo areas


6. QUICK DGT TIPS

Lights

  • Dipped beam โ†’ normal use

  • Main beam โ†’ no traffic ahead

  • Fog light โ†’ only with low visibility

Cargo

  • Always secured

  • Never overweight

People

  • Never more seats than authorized

  • Always seat belt


ULTRA QUICK SUMMARY

Lighting

Use lights according to visibility and do not dazzle.

Cargo
