The Nature and Causes of Traffic Accidents
Traffic accidents represent a major public health issue, standing as a leading cause of mortality and injury, particularly for individuals under the age of 35. In Spain, they are a primary cause of death among young people. However, it is crucial to understand that most accidents are predictable and therefore avoidable. By controlling known risk factors, we can significantly reduce their frequency and severity.
The Three Factors of Accidents
Accidents are typically caused by a combination of three main factors:
- The Human Factor: This is by far the most significant cause, responsible for between 70% and 90% of all traffic accidents. Driver-related errors, such as speeding, distractions, and risky behaviors like exhibitionism among young drivers, are the primary contributors.
- The Vehicle Factor: This includes mechanical failures or design aspects. Modern vehicles are designed with safety features, such as fronts engineered to minimize injury to pedestrians in a collision, which should not be modified.
- The Road and Environment Factor: This encompasses road conditions, weather, and signage.
When and Where Accidents Occur
Accident patterns show clear trends related to time and location:
- Time of Year: Most accidents occur during holiday periods like Easter, summer, and December, as well as on weekends, particularly in the early morning hours.
- Time of Day: During weekdays, accident rates peak during commuting times. Most daytime accidents happen in the late afternoon as people return from work. For child pedestrians, the most dangerous time is at the end of the school day.
- Weather: Good weather can also be a risk factor. For example, more cyclist accidents happen in the summer simply because more people are out cycling.
- Location: Pedestrians suffer the most accidents in cities, but their injuries are often more severe on interurban roads due to higher speeds. A significant number of pedestrian knockdowns occur when a vehicle is reversing due to reduced visibility.
Vulnerable Road Users
Certain groups are at a higher risk in traffic. The main vulnerable groups are children, young people, and the elderly.
Pedestrians
Children and the elderly are the pedestrian groups most at risk.
- Children: Their short stature makes them less visible and exposes vital body parts in a collision. They are also vulnerable because they have not yet fully developed safe road behaviors and can be easily distracted.
- The Elderly: This group is more prone to accidents in complex situations that require a quick response. Interestingly, elderly pedestrians tend to have fewer accidents when accompanying children, as they exercise greater caution.
Riders of Two-Wheeled Vehicles
Motorcycle, moped, and bicycle riders face the highest risk of severe injury or death in an accident.
- Motorcycles and Mopeds: The most frequent type of accident is a frontal or front-lateral collision with another vehicle. Not wearing a helmet is a leading cause of death in these accidents.
- Bicycles: Head injuries are the most serious and common injuries in cycling accidents, making helmet use absolutely essential.
Consequences of Accidents
The impact of traffic accidents is vast and multifaceted. Higher speeds not only increase the risk of an accident but also dramatically increase the severity of injuries.
Costs of Accidents
Accidents generate enormous costs, which are ultimately borne by all citizens. These can be categorized as:
- Material Costs: Damage to vehicles, cargo, the road itself, and the surrounding environment.
- Healthcare Costs: Expenses for medical treatment, rehabilitation, and long-term adaptation for injured victims.
- Administrative Costs: Police, fire, and judicial services.
- Human Costs: The immeasurable cost of suffering, loss of life, and reduced quality of life.
How to Act in an Accident: The PAS Rule
If you are involved in or witness an accident, you must follow the PAS protocol: Protect, Alert, and Assist.
Protect the Scene
Your first priority is to make the area safe to prevent further accidents. Immobilize any vehicles involved by applying the handbrake and switching off the ignition. Use warning triangles and hazard lights as required.
Alert Emergency Services
Call for help immediately. Dial 112, the universal European emergency number. This call is free and works even without mobile network coverage. You must notify the authorities if any party involved in the accident requests it.
Assist the Victims
You have a legal obligation to assist accident victims, unless help is already organized and present at the scene. If professionals are already managing the situation, continue on your way without slowing down to look, as this can cause traffic jams and secondary accidents.
Key Principles of First Aid:
- Do Not Move the Injured: Move a victim only if there is an immediate and unavoidable danger (e.g., fire). Unnecessary movement can worsen injuries, especially to the spine.
- Do Not Remove a Motorcyclist's Helmet: As a general rule, you must never remove the helmet from an injured motorcyclist or moped rider. Doing so can cause catastrophic neck and spinal cord injuries. Only remove it if it is absolutely essential for them to breathe and you know the correct, safe technique.
- Do Not Give Food or Drink: Never give an accident victim anything to eat or drink, especially not alcohol. Also, do not administer any medication or tranquillisers.
- Basic Life Support: Only trained and specialized personnel should perform advanced procedures like basic life support. If you are trained, your first step before attempting mouth-to-mouth resuscitation is to ensure the victim's airway is clear and open.
