Ambulance Slide Puzzle

In the period of an epidemic, and even more so a pandemic, specialized ambulances become the main and popular transport. All the available cars are being put into operation, so we decided to scrape through the susekas and found several vans and even one motorcycle. Which of them can be used is up to you to decide, but first you must assemble each vehicle from the pieces, choosing a set of fragments from simple to complex. The more difficult the level, the smaller the pieces of the puzzle and, accordingly, there are more of them.
