What is the required minimum distance to signal before turning or changing lanes in Missouri?

In Missouri, the law requires drivers to signal a minimum of 100 feet before making a turn or changing lanes. This distance is important because it provides adequate warning to other drivers and pedestrians about your intended actions. Signaling in advance allows others on the road to anticipate your movements, thereby enhancing safety and reducing the likelihood of accidents.

When making a turn or changing lanes, proper signaling helps ensure that other road users can react appropriately and adjust their speeds or positions accordingly. Signaling at this distance is also a critical part of safe driving practices and is part of the standardized expectations for commercial drivers as well as general motorists. This emphasis on advance signaling promotes overall traffic flow and communication on the roads.
