Overview
Road traffic injuries are physical harms caused by collisions or other traffic-related events involving cars, buses, trucks, motorcycles, bicycles, or pedestrians. Injuries may affect the head, neck, chest, abdomen, spine, arms, or legs. The effects can be short term or long term, and some crashes cause permanent disability or death.
Key Symptoms
Symptoms after a road crash depend on which body parts were injured. They can include pain, swelling, bleeding, bruising, dizziness, headache, confusion, trouble breathing, weakness, numbness, or difficulty walking. Some people may also have emotional symptoms such as fear, distress, sleep problems, or trouble concentrating after the event.
Causes and Risk Factors
Road traffic injuries are caused by crashes, sudden stops, rollovers, being struck by a vehicle, or being thrown from a vehicle. Risk rises with speeding, distracted driving, alcohol or drug use, fatigue, unsafe road conditions, poor visibility, and failure to use seat belts, child restraints, or helmets. Motorcycle riders, pedestrians, and cyclists often face greater physical exposure during a crash.
Who Is Affected
Road traffic injuries can affect people of all ages in every country. Drivers, passengers, pedestrians, cyclists, and motorcyclists are all at risk. Children, older adults, and people who use roads in areas with heavy traffic or weaker road safety systems may face added vulnerability.
Prevention
Prevention includes wearing a seat belt on every trip, using age-appropriate child restraints, and wearing a helmet when riding a motorcycle or bicycle where recommended or required. Avoid driving after alcohol or drug use, do not use a phone while driving, follow speed limits, and stay alert to road and weather conditions. Pedestrians can lower risk by using sidewalks, crossings, and visible clothing when possible.
Diagnosis and Tests
Healthcare professionals assess road traffic injuries by asking what happened and checking the body for signs of trauma. They may examine alertness, breathing, pulse, bleeding, movement, and sensation. Tests can include X-rays, ultrasound, CT scans, MRI, blood tests, or monitoring for concussion or internal injuries, depending on the situation.
Treatment Categories
Treatment depends on the type and severity of injury. Care may include wound cleaning, bleeding control, splinting, imaging, monitoring, surgery, rehabilitation, and support for pain, mobility, or emotional recovery. Follow-up care can be important because some symptoms and complications appear after the initial event.
Living With It
Recovery can take time, especially after fractures, head injuries, spinal injuries, or major soft-tissue damage. Some people need physical rehabilitation, mobility aids, mental health support, or help returning to work, school, or daily activities. Keeping follow-up appointments and watching for new or worsening symptoms can support safer recovery.
When to Seek Medical Care
Seek medical care after a road crash if there is pain that does not improve, swelling, limited movement, headache, dizziness, vomiting, confusion, numbness, weakness, or any concern about injury. Medical review is also important for pregnant people, infants, older adults, and anyone with a blow to the head or possible neck or back injury. Even if someone feels well at first, delayed symptoms can happen.
When It May Be an Emergency
Get emergency help right away after a crash for severe bleeding, unconsciousness, seizures, chest pain, trouble breathing, severe headache, repeated vomiting, major burns, suspected broken bones with deformity, paralysis, or signs of neck, spine, or internal injury. Call local emergency services if a person is trapped, cannot be safely moved, or is not responding normally. If there is immediate danger from traffic, fire, or fuel, move to safety only if it can be done without causing more harm.
