Before pulling out to pass on the highway you must?

Signaling your intention before pulling out to pass on the highway is crucial for ensuring safety and communication with other road users. When you signal, you are informing drivers behind you and in adjacent lanes that you plan to change your position on the road. This allows them to anticipate your actions and adjust their speed or position accordingly, reducing the risk of collisions.

Being clear about your intentions is especially important on high-speed roads like highways, where space and time are limited. It helps maintain traffic flow and ensures that other drivers are aware of your maneuver, thus promoting safer driving practices.

Checking your mirrors is an important step as well, as is looking for oncoming vehicles. However, these actions support the process of signaling rather than replace the need to communicate your changes in direction or lane. Acceleration must be managed properly, but without the signal, other drivers may not know your intentions, which is why signaling is the necessary first step.
