When it comes to safety, we often think of brakes, tires, and lights first, or check for a high-visibility vest, warning triangle, and first-aid kit. And of course, everyone buckles up before departure. But we often overlook the cargo in the car's interior. Loose items can quickly become dangerous projectiles during sudden braking or evasive maneuvers.

High impact, high risk

The danger lies in physics[1]: in the event of a sudden stop or head-on collision at 50 km/h unsecured objects can hit with up to 50 times their original weight. Even at lower speeds, the force is considerable. Fragile items like glass bottles can pose a serious risk of injury – when they shatter on impact, sharp shards may become dangerous flying objects.

Be cautious with glass, prefer plastic

The ADAC conducted a crash test to demonstrate the dangers of unsecured items and offers practical advice[2]: avoid placing fragile objects openly in the car’s cabin. ADAC spokesperson Michael Gebhardt explains: "The risk of glass bottles breaking in a crash and causing injury from the shards is definitely there. If bottles are carried in closed bags, the risk can be greatly reduced. Alternatively, using plastic bottles is a safer option."

Conclusion

When packing your car, and especially when placing items in the cabin, be extra careful. Secure loose objects properly and – for drinks on the go – plastic bottles are the safest bet. That way, you're ready to enjoy your trip with peace of mind.
