What maneuver should a driver execute if they are about to pass another vehicle on the right?

When preparing to pass another vehicle on the right, it is essential for the driver to check that the vehicle ahead is turning left. This is critical because if the vehicle they are passing is signaling a left turn, it may be moving into the lane that the driver intends to use for passing. A left-turning vehicle creates an immediate hazard, as the passing driver must ensure that they have enough space and time to safely execute the maneuver without interfering with the other vehicle’s turn.

Moreover, checking the left-turning vehicle allows the driver to anticipate potential changes in road conditions, ensuring not only their own safety but the safety of others on the road. This maneuver emphasizes the importance of situational awareness and making informed decisions while driving.
