We have two SUV’s and one truck. Drove over (slowly) without any problems. Much better than I expected. Part 2: This is the second season (spring , summer, fall ) that I have used these. They are game changers for me and my water hose protection . I have placed bricks on both sides of some of them, which helps distribute the weight so as the vehicle drives on the bricks first. I did this where we have heavy vehicles and a trailer going over it. I now have FOUR sets . Love these things.
