As temperatures drop, many drivers get behind the wheel still wearing thick winter jackets. But safety experts warn that this common habit can significantly increase the risk of injury, even in minor accidents.
A crash simulation at just 16 km/h revealed that when a driver wears a bulky coat, the seat belt fails to sit correctly across the hips. Instead, it rides too high on the abdomen, pressing against soft tissue and internal organs. According to safety specialists, this poor positioning can lead to serious injuries in even low-speed collisions or sudden braking.
The risk is even greater for children. In a proper fit, the lap belt should sit snugly across a child’s thighs, something impossible when a thick winter coat creates extra space beneath the belt. Experts emphasize that in child seats, the belt must always make direct contact with the body.
Other winter clothes that pose risks
Winter clothing isn’t limited to jackets—and several other cold-weather items can compromise safety. Hats and scarves may obstruct a driver’s field of vision, while padded gloves can reduce grip on the steering wheel. The findings come from crash tests conducted by the German automobile association ADAC.
Footwear matters as well. Heavy winter boots can make it harder to accurately control the accelerator and brake pedals, potentially delaying a driver’s response time.
Although wearing a jacket in a vehicle is not prohibited, drivers must remain able to react quickly in all circumstances. ADAC recommends removing bulky coats before entering the car or at least fastening the seat belt first and then pulling the jacket over it. Another option is to keep the jacket unzipped while driving.
Pre-heating the car before setting off can help reduce the temptation to stay bundled up. But the safest option, experts say, is simple: buckle up first, without the coat.
