Why is it important to signal before turning or changing lanes?

Signaling before turning or changing lanes is crucial because it gives other motorists adequate time to react to your intended movement. This communication is essential for maintaining safety on the road; when a driver signals their intention, it allows other vehicles to adjust their speed or position accordingly, helping to prevent accidents. Proper signaling facilitates smooth traffic flow and enhances mutual understanding among drivers, contributing to overall road safety.

In contrast, the other options do not accurately reflect the purpose of signaling. Signaling is not intended to invite other motorists to come closer or to inform them of a breakdown. Additionally, distracting other motorists is not a safe or appropriate practice on the road. It's the proactive sharing of information through signaling that preserves safety for everyone on the road.
