Can You Drive With An Empty Cargo Box?
A cargo box mounted to your roof, hitch, or truck bed can provide extra carrying capacity when you need it. But is it safe to drive with an empty cargo box still attached when not in use? In this article, we’ll explore the considerations around driving with an unused cargo box and provide recommendations to optimize safety.
The Short Answer
Generally speaking, it is safe to drive with an empty cargo box as long as you take proper precautions. An unused cargo box can reduce fuel economy, impact handling, and potentially detach if not secured properly. Following guidelines around vehicle loading, box installation, and regular maintenance will minimize risks.
How an Empty Cargo Box Affects Your Vehicle
Having an empty cargo box installed on your vehicle can impact several aspects of performance:
- Aerodynamics – More drag and wind resistance, reducing fuel efficiency
- Handling – Extra weight up high can affect steering and braking
- Suspension – Potential sagging if loaded capacity not utilized
- Visibility – Roof-mounted boxes obstruct rearview
These factors are more pronounced with larger cargo boxes, but should be considered even for smaller, empty units.
“I remove my hitch-mounted cargo box when not camping to improve gas mileage and handling. It only takes a few minutes to remove and re-install when I need it.” – James K., auto enthusiast
Steps to Drive Safely with an Empty Cargo Box
Here are some tips to follow for safe driving with an unused cargo box:
- Remove the box if not needed for an extended period of time
- Ensure the box is properly secured and locked to mounting system
- Inspect clamps and fastening hardware regularly
- Drive cautiously, especially around turns and in windy conditions
- Allow extra stopping distance without the downward weight of cargo
- Be mindful of reduced visibility directly behind you
Taking these preventative measures will help mitigate the risks associated with the additional weight and drag of the cargo box.

Weight Distribution and Loading
When driving without cargo, avoid placing other gear in the passenger cabin or bed to make up for the missing downward weight. This can upset the front-to-rear weight distribution. Instead, remove or reposition roof-mounted boxes to lower the vehicle’s center of gravity when empty.
Cargo Box Types and Considerations
Certain cargo box characteristics impact driving dynamics:
- Roof boxes – High positioning greatly affects handling. Remove when not needed.
- Truck bed boxes – Minimize air drag if not carrying cargo.
- Hitch racks – Obstruct rear view and license plate. Swing away when empty.
- Ladder racks – Can whistle or vibrate. Remove if unused.
- Utility trailers – Major reduction in fuel economy while towing empty.
Inspect each box type according to manufacturer guidelines to ensure proper mounting and security.
Key Takeaways
- An empty cargo box decreases fuel efficiency and alters vehicle handling
- Proper box mounting, locks, and hardware should be verified
- Remove roof boxes if not in regular use
- Adjust driving for reduced visibility and weight dynamics
- Check specific box guidelines and loading capacities
With preparation and awareness, unused cargo boxes can be driven safely. But it’s best to remove them when possible to optimize your vehicle’s performance. By following the tips in this article, you can maximize safety and prevent any issues caused by empty cargo boxes.
