Yes, it is possible to go through a car wash with roof racks, but it depends on the type of car wash and the type of roof rack you have. Some car washes have height restrictions, so it's important to check with the car wash first to ensure that your vehicle with the roof racks will fit. Additionally, some types of roof racks may not be suitable for car washes, such as those that are not securely attached to the vehicle or those that are made of materials that could potentially damage the car wash equipment or other vehicles. It's always a good idea to remove any loose or detachable items from the roof rack before entering a car wash to avoid the risk of damage or injury.
