Must you put your arm around passenger seat before reversing?

While it's not a legal requirement to put your arm around the passenger seat before reversing, it's a good practice to improve visibility and awareness of your surroundings. This method, often referred to as the "turning your head" technique, allows you to check for pedestrians, obstacles, and other vehicles. Always ensure your mirrors are adjusted properly as well for added safety. Ultimately, the key is to prioritize safety and be aware of your environment when reversing.
