Why should you keep well back before overtaking a large vehicle or lorry?

Keeping well back before overtaking a large vehicle or lorry is crucial because it allows you to get the best view of the road ahead. Large vehicles can obscure your line of sight, making it difficult to determine if the road is clear for overtaking. By maintaining a safe distance, you can see beyond the vehicle and assess the conditions, including the presence of oncoming traffic, road hazards, or potential obstacles. This enhanced visibility is essential for making a safe and informed decision when it comes to overtaking, ensuring that you can execute the maneuver without endangering yourself or others on the road.
