What indicates a vehicle's readiness to merge onto a freeway?

A vehicle's readiness to merge onto a freeway is best indicated by the driver signaling their intentions clearly. Signaling is a vital part of safe driving as it communicates to other drivers what the intention is, allowing for smoother and safer merging. When a driver uses their turn signal, it alerts other road users to the upcoming maneuver, ensuring that everyone can adjust their actions accordingly — whether that means slowing down, speeding up, or maintaining their lane. This communication is essential in high-speed environments like freeways, where quick and decisive actions are necessary for safety.

Other aspects mentioned, such as the vehicle reaching maximum speed or taking a wide turn, do not inherently indicate readiness to merge. The presence of another vehicle behind does not convey Information about the driver's intent, and thus is not a reliable indicator either. Consequently, clear signaling becomes crucial in establishing readiness to merge in a safe and predictable manner.
