How to Legally Install a Cargo Box on a Small Truck?
3 Answers
Installing a cargo box on a small truck is illegal. According to regulations, cargo vehicles can only be equipped with windshields, water tanks, toolboxes, and spare tire racks. Other modifications are not allowed. Common illegal modifications for trucks include: brake sprayers, changing the height of the side panels, extending the cargo box, converting side panels into cargo boxes or vice versa. Illegal vehicle modifications refer to unauthorized changes to the structure of a vehicle that has already obtained a road transport certificate without approval from relevant authorities. These mainly include the following aspects: 1. Unauthorized changes to the vehicle type or purpose; 2. Unauthorized changes to the vehicle's color, replacement of the engine, body, or frame, without applying for a change of registration with the vehicle management office within ten days after the modification; 3. Unauthorized changes to the vehicle's appearance (such as modifying the exhaust pipe, adding large body kits, or large rear spoilers) and registered technical data; 4. Unauthorized changes to the vehicle's external dimensions or load limits.
To legally install a cargo box, you must first understand the regulations thoroughly. Last year, I modified the cargo compartment of a small truck and specifically studied the 'Motor Vehicle Registration Regulations' and National Standard GB 7258. The key points are that the filing procedures cannot be skipped, the dimensions must be kept within the original vehicle's length and width, and the cargo box structure must be sturdy and reliable. I directly engaged a certified modification workshop for the design, opting for lightweight aluminum alloy materials, ensuring the total height did not exceed 2.5 meters. After installation, I immediately went to the DMV to complete the change registration, re-stamped the chassis number, took photos, and updated the vehicle license. It's crucial not to obstruct the license plate lights or reverse lights, and the cargo box floor must not extend beyond the outer edge of the tires—these details are particularly critical during inspections. It's advisable to check with the local DMV for specific standards before modification, as enforcement may vary by region.
As someone who frequently engages in transportation, I prioritize two key aspects when modifying cargo boxes: compliance with regulations and practical safety. Firstly, the extended cargo box must not exceed the original vehicle dimensions, and the width should be less than the outer width of the tires; otherwise, it will definitely be inspected on the road. The materials must meet the original factory specifications—I opt for galvanized steel plates with anti-slip patterns, which are more durable than wooden cargo boxes. Here’s the crucial part: within 7 days after modification, you must register the changes at the vehicle management office, bringing the vehicle registration certificate, ID card, and the modification shop’s qualification certificate. Paying a small fee of a few dozen yuan will make it legal for road use. Finally, don’t forget to install anti-collision bars and reflective stickers—these not only enhance nighttime safety but are also mandatory checks during annual inspections.
