Exclusive content for the DGT theory exam focused on:

• basic vehicle mechanics

• active and passive safety elements

• traffic accidents

• basic maintenance

• common exam mistakes

1. BASIC VEHICLE MECHANICS

Engine

It is the element that:

• generates the energy to move the vehicle

💡 DGT key point:

An engine failure may prevent safe driving.

Braking system

Allows you to:

• reduce speed

• stop the vehicle

Types of braking:

• service brake (pedal)

• parking brake (hand)

💡 Frequently asked:

The service brake is the main one.

Tyres

Function:

• the only contact with the road

Risks:

• wear

• incorrect pressure

• lack of tread

💡 DGT key point:

Tyres in poor condition increase the risk of accident.

Steering

Allows you to:

• control the vehicle's trajectory

A failure may cause:

• loss of control

Suspension

Function:

• absorb road irregularities

• maintain stability

2. SAFETY ELEMENTS

Active safety

Prevents accidents.

Includes:

• brakes

• tyres

• lights

• steering

• suspension

💡 Frequently asked:

Active safety acts before the accident.

Passive safety

Reduces damage in case of accident.

Includes:

• seat belt

• airbags

• headrests

• vehicle structure

💡 DGT key point:

Passive safety acts during the accident.

Seat belt

Mandatory for:

• driver

• passengers

Functions:

• prevent ejection

• reduce injuries

Airbags

Function:

• protect in collisions

They do not replace the seat belt.

💡 Frequently asked:

The airbag always complements the seat belt.

Headrest

Function:

• prevent cervical injuries

Bodywork

Absorbs impact energy to protect occupants.

3. TRAFFIC ACCIDENTS

Main causes

• distractions

• inappropriate speed

• alcohol and drugs

• fatigue

• poor vehicle condition

💡 Frequently asked:

The human factor is the main cause of accidents.

Types of accidents

Head-on collision

High severity.

Rear-end collision

One vehicle hits another from behind.

Run-off-road

Loss of vehicle control.

Run-over

Vehicle hits a pedestrian or cyclist.

Consequences of accidents

• injuries

• material damage

• fatalities

Conduct after an accident

PAS (Protect, Alert, Aid)

Protect

Prevent further accidents.

Alert

Call emergency services.

Aid

Help the injured without putting yourself at risk.

💡 Frequently asked:

Do not move the injured unless there is serious danger.

4. BASIC MAINTENANCE

Vehicle check

The following must be checked:

• tyres

• brakes

• lights

• fluid levels

Vehicle fluids

• oil

• coolant

• brake fluid

Tyre pressure

It must be checked:

• regularly

• when cold

Lights

They must work properly in order to:

• see

• be seen

5. DRIVING SAFETY

Safety distance

Allows you to:

• stop the vehicle without collision

💡 Rule:

The greater the speed → the greater the distance.

Appropriate speed

Must be adapted to:

• road conditions

• weather

• traffic

Preventive driving

It consists of:

• anticipating risks

• avoiding dangerous situations

6. COMMON EXAM MISTAKES

• confusing active and passive safety

• thinking that the airbag replaces the seat belt

• forgetting PAS in accidents

• not checking tyres correctly

• ignoring the importance of the human factor

7. DGT TIPS

Active safety

Prevents accidents.

Passive safety

Reduces injuries.

PAS

Protect → Alert → Aid.

Tyres

They are key to safety.

Human factor

Main cause of accidents.

ULTRA-QUICK SUMMARY

Basic mechanics

Brakes, tyres, steering, suspension.

Active safety

Prevents accidents.

Passive safety

Reduces damage.

Accidents

Main cause: human factor.

PAS

Protect, alert and aid.
