How can I safely carry plywood on a roof rack?

To safely carry plywood on a roof rack, make sure to secure the plywood with straps or ropes to prevent it from shifting or falling off while driving. Use padding or a tarp to protect the roof rack and the plywood from damage. Check the weight capacity of your roof rack and distribute the weight evenly to avoid overloading. Drive carefully and avoid sudden movements to ensure the plywood stays secure during transport.
