Alcohol, Drugs, Medication, Fatigue and Fitness
Alcohol
Alcohol slows reactions, impairs judgement and reduces balance - all critical on a motorcycle. Belgium applies legal blood-alcohol limits, and novice riders face stricter rules. Even below the limit, alcohol affects riding. The safe answer is always: do not drink and ride. A trap is thinking coffee, food or fresh air speeds up sobering; only time does.
Drugs and medication
Illegal drugs are prohibited. Many prescription and over-the-counter medicines cause drowsiness; read the label and ask a pharmacist or doctor. Do not ride if a medicine warns against driving. Combining alcohol with medication multiplies the effect.
Fatigue
Tiredness reduces concentration and reaction time. Take regular breaks on long rides, stop if you feel drowsy, and avoid riding late at night after a long day. A common trap is believing energy drinks replace rest; they do not.
Fitness to ride
Illness, stress, poor eyesight and strong emotions all affect riding. Ensure your vision is adequate and your protective equipment is comfortable. If you feel unwell, do not ride.
Worked example
After an evening with friends you feel fine to ride home. You should not. Impairment can be present even when you feel alert, and the only reliable remedy is time.
