What must you do when preparing for a right turn?

The correct answer emphasizes the critical steps necessary for safely making a right turn. Signaling at least 100 feet in advance informs other road users of your intention to turn, which is a fundamental traffic rule designed to enhance safety. This advance signaling allows drivers behind you and pedestrians to understand your movements, reducing uncertainty on the road.

Checking traffic to the rear is important to ensure that no vehicles are approaching from behind before you begin your turn. This is particularly crucial in situations where you may need to stop or slow down to make the turn, preventing potential collisions.

Driving in the right-hand lane is also essential, as it positions your vehicle appropriately for the turn and further conveys your intention to other drivers. In many cases, traffic laws require that right turns be made from the rightmost lane whenever possible, providing a clear pathway for both your vehicle and others using the thoroughfare.

Following these protocols enables a safer environment for all road users during turns, underscoring the importance of proper signaling, awareness of surrounding traffic, and adherence to lane discipline.
