Compared to roof boxes, are back boxes safe?

When choosing extra storage for your car, safety is always the top priority. Roof boxes have been around for decades, but are they really as safe as rear mounted boxes? Let’s compare.

Stability on the road

Roof boxes sit on top of the car, which raises the center of gravity. This can affect handling, especially in sharp turns, crosswinds, or emergency situations.
Back boxes, mounted on the tow hitch, keep the weight lower and closer to the car’s frame. This improves stability and reduces the risk of rollover.

Crash performance

In a collision, roof boxes are more exposed and can detach if not mounted correctly. They may also cause extra damage to the car’s roof or windshield.
Back boxes are secured to the tow hitch – one of the strongest parts of the vehicle. Crash-tested rear boxes, like IXTAbox, are designed to stay firmly in place, keeping both passengers and cargo safer.

Everyday safety factors

Mounting: Roof boxes require lifting heavy loads above your head, which can cause injuries. Back boxes are mounted at waist height – safer and easier.
Visibility: Roof boxes can block panoramic roofs or sensors, while back boxes stay out of sightlines.
Braking: Extra weight on the roof can affect braking distance more than weight placed at the rear.
