If a driver is merging into your lane, what should you do?

When a driver is merging into your lane, the safest and most responsible action is to adjust your speed or position to allow for their safe entry. This approach promotes road safety by minimizing the risk of collisions. Merging can often create tight situations, especially if the merging vehicle is having difficulty finding a gap or if their speed differs from yours. By adjusting your speed—either slowing down slightly or changing lanes if it's safe—you provide the merging driver with the space they need to enter your lane safely and reduce the likelihood of a dangerous situation.

Maintaining your speed or ignoring the merging vehicle could lead to a collision or force the other driver to make sudden maneuvers, which can be very hazardous. Speeding up to prevent their entry could escalate tensions on the road and make the situation worse, potentially resulting in an accident. Signaling for the other driver to stop does not address the immediate need for safety and could create confusion and further hazards on the road. Hence, the most constructive action involves being cooperative and accommodating as a driver, which is vital for maintaining an orderly traffic flow and ensuring everyone's safety.
