Traffic accidents serve as a warning to us: do not exceed the speed limit; learn to control speed with intermittent braking; avoid changing lanes or merging arbitrarily; increase the safe distance in adverse weather conditions. Nine out of ten accidents are caused by speeding, with excessive speed and other major traffic violations being significant contributors to traffic accidents. When driving on highways, maintaining a safe speed is the most crucial factor in ensuring safe travel. When a driver notices the vehicle ahead braking, they must use intermittent braking to alert the following vehicle. This serves two purposes: maintaining a safe distance and reminding the following vehicle to slow down, thereby avoiding rear-end collisions. Arbitrarily changing lanes on highways can disrupt traffic flow, making it difficult for vehicles behind to react in time and leading to dangerous situations. When a driver intends to change lanes, they should check the rearview mirror to ensure no vehicles are approaching from behind, confirm there is sufficient safe distance, and then activate the turn signal at least 3 seconds in advance to inform other drivers of their intention to change lanes. When encountering low-visibility weather conditions such as fog, rain, snow, dust, or hail on highways, drivers should exercise extra caution, stay alert, maintain a safe distance, and prevent rear-end collisions.

I've personally witnessed the horrific scenes of many car accidents, with the most direct impact being physical injuries. At the moment of collision, heads may smash against the steering wheel or windshield - ranging from concussions and memory loss to life-threatening intracranial hemorrhages. Injuries like being bruised by airbags or suffering rib fractures are common, but even more terrifying are spinal cord injuries causing lifelong paralysis or ruptured internal organs leading to massive bleeding. Even if one survives, the prolonged rehabilitation process is torturous, especially for amputees or severe burn victims who must endure permanent physical disabilities. Then there are the invisible wounds like post-traumatic stress disorder - some people tremble at the sound of brakes and suffer from insomnia and nightmares, psychological scars that may last a lifetime. Not to mention the medical expenses that drain away like flowing water after an accident, which ordinary families simply cannot afford.

Last time I rear-ended someone, the repair cost over 8,000 yuan, and that was just a minor scratch. If it were a major accident, the financial burden would be terrifying. The car would need to be towed to the repair shop for extensive work, costing at least 10,000 to 20,000 yuan. If someone gets injured, medical expenses and compensation could easily reach hundreds of thousands, and even more for disability. That doesn’t even include lost wages—lying in bed for a month means no income, and if you get laid off, it’s even worse. The company will definitely jack up your premium the next year, with increases often exceeding 40% at renewal. The worst part is that the at-fault party might face legal disputes, with litigation and lawyer fees adding tens of thousands more. For an average salaried worker, this could wipe out savings, force borrowing from everywhere, and even lead to selling property to pay off debts.

A single collision at an intersection can paralyze the entire road. I've witnessed a three-car pileup that resulted in a two-kilometer-long traffic jam behind. Ambulances and fire trucks were all tied up, delaying other emergency responses. Gasoline leaks require the mobilization of environmental departments to handle pollution. Accident investigations demand police resources, and courts must schedule hearings, diverting significant societal resources. Hit-and-run cases are even more resource-intensive, requiring the retrieval of surveillance footage from citywide camera systems. Road repairs also incur costs, especially when guardrails and light poles are damaged. These public expenses ultimately fall on everyone, not to mention the incalculable time costs of being stuck in traffic.

My uncle's family was completely devastated by a car accident. My cousin, who was driving under the influence, lost his life in the crash, leaving behind three children and elderly parents. His wife had to take on three to support the family, forcing their eldest daughter in middle school to drop out and work. After losing the breadwinner, they couldn’t even afford the mortgage, and the bank repossessed their home, leaving the whole family crammed into a rental. The elderly parents, unable to bear the shock, were hospitalized for six months, with medical bills piling up unbearably. The most heartbreaking part is their five-year-old son, who cries daily for his dad. This pain isn’t something that fades quickly—every year on the anniversary of his death, the family breaks down all over again. The once lively family gatherings are now a thing of the past, never mentioned again.

Ever since that fender bender last year, I've been nervous about driving. Now my palms sweat when overtaking, and my heart races when passing accident sites at night. The doctor says it's driving anxiety disorder, and I need sleeping pills to fall asleep. The sound of metal scraping is still so vivid in my memory that I freeze up whenever I hear sudden braking. This trauma affects my whole life rhythm—I decline friends' road trip invitations and insist on taking the subway even if it means being late on rainy days. Colleagues say my personality has changed; I used to be cheerful but now I'm withdrawn. Some severe cases even avoid all vehicles, experience shortness of breath at red lights, and have their entire life trajectories altered.
