How far behind a truck can a blind spot extend?

A truck's blind spot can extend up to 200 feet behind it. This is crucial information for drivers to understand because vehicles in this area are not easily visible to the truck driver. When following a large truck, it's essential to maintain a safe distance to ensure that you can see the truck's side mirrors; if you can see their mirrors, the truck driver can likely see you. Staying outside of this blind spot while maintaining proper speed and distance can help prevent accidents, especially when the truck is making turns or changing lanes. Recognizing the extent of blind spots in larger vehicles like trucks is vital for safe driving practices.
