Before starting a maneuver to merge into traffic, what factors must the driver mandatorily observe and assess?

Question

DentroTest · Accepted Answer

Merging into traffic is a basic maneuver that requires compliance with the safety rule: Mirror Signal Maneuver (MSM). Before signaling or moving, the fundamental step is observation. The driver must ensure that the maneuver can be performed without endangering other road users. This implies assessing the position, trajectory, and speed of approaching vehicles, not just from the left or right, but in the entire surrounding area (including pedestrians or vehicles that might be overtaking). If other users are forced to abruptly change their speed or trajectory, the merge is incorrect and dangerous. Therefore, looking only to one side is insufficient.
