Risk Factors in Motorcycle Riding
To obtain your motorcycle license, it is vital to understand not only how to handle the machine but also how your physical and mental state affects safety. In this topic, we analyze the most common negative elements: alcohol, drugs, sleep, and fatigue.
1. Fatigue
Fatigue is one of the "silent enemies" of the motorcyclist. Unlike driving a car, physical wear and tear on a motorcycle is greater due to postural tension and wind resistance.
Main Causes
Fatigue appears more quickly due to:
- Poor nutrition or insufficient hydration.
- Lack of experience or being unaccustomed to motorcycle riding.
- Unfaired motorcycles (Naked bikes): The lack of aerodynamic protection forces the rider to fight against the force of the wind.
- Monotonous roads or poor visibility conditions (fog, night).
- Maintaining high speeds for a long time.
Symptoms and Effects
A fatigued rider will experience a heavy head, stiffness in the neck and back (especially on sportbikes), and constant changes of posture in the seat.
| Symptom | Consequence on Riding |
|---|---|
| Imprecise reactions | Slow or erratic movements in the face of danger. |
| Loss of attention | Difficulty maintaining concentration on the road. |
| Aggressive behavior | Irritability and abrupt riding/handling. |
Exam Tip: To avoid fatigue, get plenty of rest before the trip, avoid heavy meals, and stop to rest every 2 hours.
2. Sleep and Drowsiness
Drowsiness does not only appear at night; it can arise from heavy meals or monotony.
- Main Effect: Reaction time increases (it takes longer to react) and reaction capacity decreases.
- Dangers: Increased distractions and altered motor functions.
Recommendation: Avoid riding during usual sleeping hours or after heavy food intake.
3. Alcohol and Riding
Alcohol is incompatible with safe motorcycle riding, severely affecting the nervous system and the brain.
Immediate Effects
- False sense of security: The rider feels braver and underestimates dangers.
- Tunnel effect: Reduction of the lateral visual field.
- Calculation errors: Speed and distances are incorrectly perceived.
- Imprecision: Less controlled turns and braking.
Legal Blood Alcohol Concentration (BAC) Limits
The rate is measured in grams per liter of blood (g/l) or milligrams per liter of expired air (mg/l). Exceeding these limits leads to vehicle impoundment, financial penalties, and prison sentences.
| Type of Rider | Blood (g/l) | Expired Air (mg/l) |
|---|---|---|
| General | 0.50 g/l | 0.25 mg/l |
| Novice (First 2 years of license) | 0.30 g/l | 0.15 mg/l |
Important Note: If you already hold a Category B (car) license for more than 2 years, the general rate applies when you get your A2 license, not the novice rate.
Obligation to Undergo Testing
It is mandatory to take a breathalyzer test if:
- You are involved in an accident.
- You commit a traffic infraction.
- You show obvious symptoms of intoxication.
- During a preventive checkpoint (random breathalyzer test).
4. Drugs and Medication
Not all medications prohibit driving, but many have dangerous side effects.
- Always consult your doctor or read the leaflet (package insert) if you are going to ride.
- Some drugs cause drowsiness, blurred vision, or loss of reflexes.
- Never mix medication with alcohol.
5. Guidelines for Rest and Long Trips
On motorways and dual carriageways, fatigue appears sooner due to speed and wind resistance (especially on naked bikes or those without fairings).
The 2-Hour Rule
You must make periodic stops to recover physical tone and concentration.
- Frequency: Stop at least every 2 hours, even if the motorcycle has plenty of fuel.
- What to do during the stop:
- Stretch your muscles to relieve tension.
- Check the motorcycle (oil level, lights, luggage).
- Hydrate (water or isotonic drinks).
- Eat light foods (fruit, cereals) that are easy to digest.
- If necessary, take a short nap (15-20 min).
Remember: Safe riding depends on a well-maintained motorcycle and a rider in full possession of their faculties.
