What should you do if a vehicle pulls out in front of you at a junction?

When a vehicle pulls out in front of you at a junction, the most appropriate response is to slow down and be ready to stop. This action prioritizes safety for both yourself and the other driver. By reducing your speed, you increase your chances of avoiding a collision and give yourself more time to assess the situation. It's crucial to remain vigilant and prepared for any sudden changes, as the other driver may not have fully cleared the intersection or may have misjudged the speed at which you are approaching.

In contrast, attempting to accelerate and overtake could lead to a dangerous situation, as it may provoke a collision if the other vehicle isn't fully in the lane or if it speeds up unexpectedly. Honking the horn could alert the other driver, but it does not prevent an accident and may create additional confusion instead of aiding in avoidance. Changing lanes immediately could put you at risk of side-swiping another vehicle or losing control, especially if the lane isn't clear. Staying calm, decelerating, and being prepared to stop is the safest course of action in this scenario.
