Will points be deducted for not using turn signals when changing lanes on the highway?

[GiselleLynn]

Not using turn signals can result in point deductions. Below is relevant information about turn signals: Introduction: Turn signals are important indicator lights that are activated when a motor vehicle changes direction to alert surrounding vehicles and pedestrians. The turn signal bulbs use xenon tubes, controlled by a microcontroller circuit, with alternating left and right rapid flashing for continuous operation. Turn signals utilize flashers to achieve the blinking effect. They can be mainly categorized into three types: resistance wire type, capacitor type, and electronic type. Structural Principle: The resistance wire type can be further divided into thermal wire type (electrothermal) and vane type (spring-loaded), while the electronic type can be classified as hybrid (relay with contacts and electronic components) or fully electronic (no relay). For example, the spring-loaded flasher operates on the principle of thermal expansion and contraction, using the heat effect of current to cause sudden movement of the spring strip, thereby connecting and disconnecting the contacts to achieve the blinking effect.
