On which road sections can seat belts be unfastened?

[BellaRose]

Seat belts must be fastened on all road sections. Below is relevant information about automotive seat belts: 1. Concept: Automotive seat belts are safety devices designed to restrain occupants during collisions, preventing secondary impacts with steering wheels, dashboards, or ejection from the vehicle that could cause fatalities or injuries. Also known as seat safety harnesses, they are a type of occupant restraint system. Universally recognized as the most cost-effective yet efficient safety feature, many countries mandate their installation in vehicles. 2. Working principle: The retractor stores the webbing and locks it when pulled out, making it the most complex mechanical component in the seat belt system. Inside the retractor lies a ratchet mechanism. Under normal circumstances, occupants can smoothly pull the webbing at a consistent speed, but when the webbing stops being extracted or the vehicle encounters an emergency, the ratchet mechanism activates to automatically lock the webbing, preventing further extension. Mounting fixtures include tabs, plugs, and bolts connected to the vehicle body or seat components. Their installation position and stability directly affect both the protective efficacy of the seat belt and occupant comfort.

I've been driving a taxi for over 20 years, navigating through streets and alleys every day. To be honest, there's no place on the road where I'd dare not wear a seatbelt. In city traffic jams, some people always unbuckle, but last year I witnessed a rear-end collision at an intersection where the driver in front wasn't wearing a seatbelt and fractured his ribs from hitting the steering wheel. On highways, it goes without saying - once driving at night through dense fog, if it weren't for the seatbelt holding me, I would've been thrown out. Country roads with potholes often cause head bumps from vehicle jolts. Simply put, as long as the wheels are turning, there's risk - even moving cars in parking lots can't guarantee safety. Developing the habit of buckling up as soon as you get in the car is much more practical than trying to figure out which stretches of road you can skip it on.

As an auto repair shop technician, I deal with dismantling various accident vehicles every day. The most common seatbelt buckle failures I see occur on residential internal roads and industrial area work vehicles. Customers often say 'it's just a few hundred meters,' but even the concrete curb at the workshop entrance can cause an unbelted worker to smash through the windshield. The vehicle's passive safety systems are designed to provide protection throughout the entire journey, and the dashboard warning light indicates the system is active. Special reminder for off-road vehicle drivers: those gentle-looking slopes in the wild may seem safe, but unbelted occupants suffer the most during rollovers. When the vehicle is running, unfastening your seatbelt at any moment is gambling with your safety.

I drive my child to school every day. In our residential area, I've encountered three close calls: a delivery guy suddenly darting out from the greenbelt on an e-bike, a child's ball rolling in front of the car, and a neighbor scratching my car while reversing into a parking space. Each sudden brake makes the seatbelt dig painfully into my shoulder, but that pain means it's working. Child seats have even stricter requirements - even emergency braking in the kindergarten parking lot can make the child lurch forward. We've taught our child to say 'Mommy and Daddy, fasten your seatbelts' when getting in the car, which serves as a family cross-check. Not a single minute can be relaxed on the school run - last year in the neighboring community, a mother who wasn't belted hit her head while picking up a dropped phone in the parking lot.

In the cross-province logistics industry, drivers often argue whether seat belts can be unfastened in service areas. Last week at a service area gas station, I witnessed two trailers scrape against each other, and an unstrapped crew member in the cab suffered a wrist fracture. Extra caution is needed during highway traffic jams—last year during the Qingming Festival return peak, a 20-car pileup occurred, and a co-driver in our fleet who had unfastened his seat belt lost a front tooth. Current regulations state: keep seat belts fastened as long as the engine is running, and the vehicle must be turned off when switching drivers for rest breaks. On long hauls, if feeling drowsy, open windows for ventilation or chew mint candies, but never loosen the seat belt to relieve restraint discomfort.

I've been driving a business van for my boss for seven years, and the most dangerous areas are the low-speed sections in the city. The underground parking lots in business districts have many sharp turns—once, while avoiding an electric bike going the wrong way, I hit a pillar, and an unbelted colleague ended up with a bloody nose. School zones are even more critical; I’ve encountered kids suddenly darting across the road, forcing me to slam the brakes. People often say, 'Why worry at 40 km/h in the city?' But hitting a wall at 40 km/h is like falling from the fourth floor. My rule is to buckle up as soon as I start the engine, even for quick trips to the convenience store. Last month, a rear-end collision cost 20,000 yuan in repairs, but without a seatbelt, the medical bills could have easily exceeded that.
