How can you determine if you are visible to a tractor trailer driver?

Determining visibility to a tractor trailer driver is crucial for safe riding or driving around large vehicles. When you can see the driver's face in their mirrors, it indicates that they have a direct line of sight to you. Truck drivers rely heavily on their mirrors due to the considerable blind spots around their vehicles, often referred to as "No Zones." If the driver can see you in their mirrors, it means you are in a position where they are aware of your presence, reducing the risk of collision.

Other indicators, such as a driver smiling or signaling, do not necessarily confirm their awareness of your presence in a way that affects safety on the road. The movement of the truck alone does not guarantee visibility, as the driver may be unaware of surrounding vehicles or riders. Hence, being visible in the driver's mirrors is the most reliable way to ensure you are in their line of sight.
