Which of these maneuvers does not require signaling?

Riding straight ahead without changing lanes does not require signaling because there is no intention to alter your position on the road or path of travel. Signaling is primarily used to communicate to other road users (drivers, cyclists, pedestrians) about your intentions to change direction or position, such as turning, merging, or changing lanes. When a motorcycle rider is moving straight, they are maintaining their course and do not need to alert others of any change. This keeps the road clear of unnecessary confusion and allows riders to focus on maintaining control of their motorcycle.

In contrast, making a left turn at an intersection, changing lanes on the freeway, and turning into a driveway all involve changes in direction or positioning that require signaling to inform other road users of the rider’s intentions. This enhances safety and promotes smoother traffic flow by ensuring that all vehicles are aware of each other's actions.
