1. THE DRIVER

Driver Responsibility

The driver is responsible for:

• the safe driving of the vehicle

• complying with traffic rules

• adapting their driving to the conditions

💡 Frequently asked:

Safety mainly depends on the driver.

• coordination

Physical Condition

Directly influences driving:

• fatigue

• illnesses

• medications

• sleep

Mental State

Affects driving:

• stress

• distractions

• anxiety

• intense emotions

💡 Typical DGT error:

Distraction is one of the main causes of accidents.

2. RISK FACTORS

Alcohol

Effects:

• reduces reflexes

• alters perception

• increases reaction time

💡 DGT Rule:

The only safe rate is 0.

Drugs

Effects:

• loss of control

• alteration of senses

• unpredictable behavior

Medications

Some medications can cause:

• drowsiness

• decreased reflexes

💡 Important:

Package inserts must be read.

Fatigue and Sleep

Symptoms:

• yawning

• constant blinking

• loss of attention

Consequences:

• microsleeps

• loss of control

💡 Frequently asked:

Sleep is as dangerous as alcohol.

Speed as a Risk Factor

At higher speeds:

• shorter reaction time

• longer stopping distance

• greater severity of accidents

Distractions

Main causes:

• mobile phone

• GPS

• conversation

• radio manipulation

💡 DGT Rule:

The mobile phone is one of the biggest causes of accidents.

3. EXTERNAL CONDITIONS

Rain

Causes:

• less grip

• increased stopping distance

Fog

Causes:

• reduced visibility

• difficulties in estimating distances

Snow and Ice

Risk:

• loss of control

• skidding

Wind

Can cause:

• vehicle deviations

• loss of stability

Night

Risks:

• less visibility

• eye fatigue

• glare

4. VEHICLE FACTORS

Vehicle Condition

Influences safety:

• brakes

• tires

• lights

• steering

Tires

Importance:

• they are the only contact with the road

Risks:

• wear

• incorrect pressure

Brakes

If they are in poor condition:

• increases stopping distance

Lighting

Defective lights:

• reduce visibility

• increase accident risk

5. ROAD FACTORS

Road Condition

Influences:

• grip

• vehicle stability

Curves

Risk:

• loss of control

Speed must be reduced.

Slopes

Risk:

• increased speed on descents

Construction

Risk:

• lane changes

• narrowing

6. SAFE DRIVING

Preventive Driving

Consists of:

• anticipating risks

• maintaining constant attention

Safety Distance

Must allow:

• to stop the vehicle without collision

💡 Key rule:

Higher speed → greater distance.

Appropriate Speed

Must adapt to:

• weather conditions

• traffic

• visibility

💡 Frequently asked:

The legal speed is not always safe.

7. COMMON ERRORS IN THE EXAM

• thinking that only the vehicle influences accidents

• underestimating fatigue

• confusing legal speed with safe speed

• ignoring the effects of alcohol even in small amounts

• forgetting the effect of the mobile phone

Speed

More speed = more risk.

Driver

Is the most important factor in road safety.

ULTRA FAST SUMMARY

The Driver

Mainly responsible for safety.
