What is the big box on the roof of a car?
2 Answers
A big box on the roof of a car is a rooftop luggage carrier. The rooftop luggage rack actually serves many purposes. Primarily, it increases the car's storage space. During road trips or when the car is fully loaded with passengers, the rooftop luggage rack can provide better seating space and comfort for the passengers inside the car. Below are some precautions for using a rooftop luggage carrier: 1. Before installation, ensure it does not interfere with the opening of the car's rear door. 2. Always lock the luggage carrier before driving and remove the key. 3. Do not exceed the maximum load capacity. 4. Avoid placing pets inside the luggage carrier. 5. Do not enter an automatic car wash with the luggage carrier installed. 6. Secure large items at the bottom of the carrier.
I frequently take long trips, and that big box on my car roof is the rooftop luggage carrier I installed, also known as a rooftop box. It's incredibly practical—it can hold extra camping gear like tents, sleeping bags, and food, keeping the car interior spacious. It's perfect for road trip enthusiasts like me. Installation isn’t too difficult; just secure it onto the roof rack, but make sure it’s tightly fastened—otherwise, it can create noise at high speeds or even detach. Be aware that wind resistance increases fuel consumption by about 5%, so I only use it during trips and remove it for storage afterward. When choosing one, consider size and material—hard-shell cases are more durable but pricier, while soft bags are foldable and space-saving. Always check the height to avoid hitting garage doors. Overall, it’s a great help and adds to the fun.
