How should you respond if another driver has entered your blind spot?

When another driver has entered your blind spot, the safest response is to slow down and check your mirrors. This approach allows you to reassess your position in relation to the other vehicle without making any sudden movements that could lead to an accident. By decelerating, you create more space between your vehicle and the one in the blind spot, giving you time to safely evaluate the situation.

Checking the mirrors while slowing down serves a dual purpose: it helps you confirm whether the vehicle is indeed in your blind spot or if it has moved to a more visible position. This cautious strategy ensures you maintain situational awareness and helps you avoid potential collisions when deciding to change lanes or take any further action.

Other options may lead to unsafe driving practices. Accelerating to pass without confirming your surroundings can increase the risk of a crash, as it may place both vehicles too close together at higher speeds. Turning on your sirens is appropriate in emergency situations, but it does not address the issue of blind spots or offer any solution for safe lane changes. Changing lanes immediately without confirming the space around you can lead to dangerous situations, making it vital to assess the surroundings first.
