What is the minimum distance required when passing another vehicle?

Answer: B — 1.5 meters

The minimum distance required when passing another vehicle is 1.5 meters, which is designed to ensure safety for both the overtaking driver and the vehicle being passed. Maintaining this distance helps prevent accidents by providing a buffer zone that reduces the risk of side mirrors colliding or wind turbulence causing instability for the vehicles. Additionally, it allows for any sudden movements from the other vehicle or unforeseen circumstances that could arise while passing. This distance reflects the need for a safe and controlled environment on the road, particularly in diverse driving conditions and with varying vehicle sizes.
