Alcohol and Driving
A Moment's Mistake, A Lifetime of Regret: The Truth About Alcohol and Driving
Every time we hit the road, we are essentially signing a major pact of trust. We trust the driver coming from the opposite lane, the student waiting at the crosswalk, or the vehicle stopped at the red light. However, the greatest threat that shakes this trust—and destroys not only rules but lives—remains unchanged: Driving under the influence of alcohol or drugs.
So, what are the scientific and vital truths behind statements like "I'm fine," "I only had two drinks," or "My house is right there"? Let's take a closer look at the "invisible effects" of alcohol behind the wheel.
The "I Feel Fine" Illusion
The most dangerous side effect of alcohol is the "false sense of confidence" that emerges before actual intoxication sets in. As blood alcohol levels rise, the brain shuts down its perception of danger and increases the tendency to take risks. The driver is unaware that their reflexes have slowed; on the contrary, they believe they are more skilled than usual. A large percentage of accidents occur exactly during this "I can handle this" moment.
What Happens to Your Body?
Alcohol is a substance that suppresses the central nervous system. When you get behind the wheel, the following changes occur in your body:
Increased Reaction Time: When you see a vehicle or pedestrian suddenly appear, your braking time is measured in fractions of a second. Alcohol slows this time down to life-threatening levels.
Tunnel Vision Sets In: While you can normally scan side mirrors, blind spots, and surrounding traffic, alcohol narrows your field of vision. You focus only on what is directly in front of you and become unable to detect dangers approaching from the sides.
Loss of Depth Perception: Your ability to accurately judge the distance to the vehicle ahead or the sharpness of a curve is lost.
Common Myths and Facts
Unfortunately, in our traffic culture, many drivers act based on hearsay. It is vital to correct these misconceptions:
MYTH: "I'll sober up if I drink coffee or wash my face."
FACT: Coffee might wake you up, but it does not clear the alcohol from your blood or restore your reflexes. The only thing that can eliminate the effects of alcohol is time.
MYTH: "I'll open the window and get some fresh air."
FACT: Fresh air might be good for your lungs, but it cannot stop the impairment occurring in your brain.
Even if Blood Alcohol Concentration (BAC) reaches a level as low as 0.02 g/dL, effects such as a decline in visual functions and a reduced ability to perform two tasks simultaneously (divided attention) emerge. The severity of this situation is highlighted by statistics: In 2023, 2,117 people lost their lives in alcohol-related accidents where the driver's blood alcohol level was between 0.01 and 0.07 g/dL. This fact reinforces the core message: "Buzzed driving is drunk driving." This debunks the "I only had a few drinks" excuse and proves that any amount of alcohol carries risk.
A Technical Perspective: What is BAC?
The technical term for "Promil," which we often hear during traffic stops, is BAC (Blood Alcohol Concentration). Simply put, it indicates the amount of alcohol in grams present in 100 milliliters of blood.
Critical factors affecting the alcohol level in your blood:
- Gender: Biologically, women have a lower body water percentage than men, and the enzymes that break down alcohol function differently. Therefore, when consuming the same amount of alcohol, a woman's BAC usually rises faster than a man's.
- Body Weight: A heavier person has more blood and water in their body, allowing for greater dilution of alcohol. Alcohol concentration rises faster in individuals with lower body weight.
- Stomach Status (Empty/Full): Perhaps one of the most decisive factors. When consumed on an empty stomach, alcohol passes directly into the small intestine and enters the bloodstream like a rocket. When consumed on a full stomach, absorption slows down.
- Rate of Consumption: Your liver can only process a certain amount of alcohol per hour (approximately 1 standard drink). If you drink faster than this rate, the liver cannot keep up, and blood alcohol levels rise rapidly.
- Fatigue and Medications: While physical fatigue or certain medications may not directly change blood alcohol levels, they increase the perceived effects of alcohol.
Remember: Saying "I have a high tolerance" does not change the alcohol ratio in your blood. The breathalyzer measures the chemical balance in your veins, not your feelings.
Blood Alcohol Concentration (Promil) and Its Predictable Effects on Driving
0.20 Promil (0.20): Alteration in mood, slight rise in body temperature, reduced control over behavior.
0.50 Promil (0.50): Distinct relaxation, reduced attention, onset of impairment in coordination and judgment. (Legal Limit for Private Vehicles)
0.80 Promil (0.80): Significant impairment in coordination, perception, and judgment; damage to reaction time and self-control skills.
1.00 Promil (1.00): Signs of drunkenness, potentially embarrassing behaviors, mood swings (fluctuating between happy and sad).
1.50 Promil (1.50): Difficulty standing, walking, and speaking; loss of balance and coordination; obvious state of intoxication.
2.00 Promil (2.00): Reduced perception of pain and other physical stimuli; distinct emotional inconsistency (fluctuating between crying and laughing).
3.00 Promil (3.00): Reduced reflexes in many people, confusion, loss of consciousness.
Legal Regulation (Article 48/5):
Driving with a blood alcohol level above 0.50 promil is prohibited. For Private Cars:
Driving with a blood alcohol level above 0.20 promil is prohibited.For Other Vehicles

The Price is Not Just Your License
The penalty for drunk driving is not limited to monetary fines or the suspension of your driver's license. The highest price you pay is the irreversible harm you may cause to your loved ones, an innocent pedestrian, or yourself. A fleeting moment of pleasure or the thought of "saving money on a taxi" can transform into a lifetime of remorse.
Legal Consequences: Turkish Penal Code Article 179 "Endangering Traffic Safety" – You May Face Prosecution.
"Any person who causes danger to the life, health, or property of others by altering, rendering unusable, or removing any sign placed to ensure the safe flow of land, sea, air, or railway transportation; by giving false signals; by placing an obstacle on passage, arrival, departure, or landing paths; or by interfering with technical operating systems, shall be sentenced to imprisonment for a term of one to six years."
Your Safest Road Partner is Your "Reason"
- If you intend to consume alcohol, make your plan before you ever get behind the wheel.
- Designate a Driver: Select a "voluntary driver" (a friend who will not drink).
- Use Technology: Utilize taxis or ride-hailing applications.
- Choose Public Transport: Opt for buses, metros, or other public transit options.
Article 48/5: Legal Limits and Penalties Legal Limits:
For Private Automobiles: Driving with a blood alcohol level above 0.50 promil.
For Non-Private Vehicles (Commercial, etc.): Driving with a blood alcohol level above 0.20 promil.
Conditions for License Reinstatement: For a driver's license to be returned at the end of the suspension period, the conditions listed below must be met, and all administrative fines issued pursuant to Law No. 2918 (Article 48 and all other articles) must be paid in full.
According to this article, regarding suspended licenses:
2-Year Suspension: Drivers whose licenses are suspended for two years must undergo Driver Behavior Development Training (SÜDGE).
5-Year Suspension: Drivers whose licenses are suspended for five years must undergo a psycho-technical evaluation and an examination by a psychiatry specialist.
