The Overtaking Opportunity on a Coastal Road
You are driving a van on a two-lane coastal road in Maldives. The road has a solid white line on your side, indicating no overtaking. The speed limit is 60 km/h. You are following a slow-moving truck carrying construction material at 30 km/h. The truck is emitting dust and debris. You have been stuck behind it for 5 minutes. Ahead, the road curves to the right, and you cannot see beyond the curve. There is a sign indicating a junction 200 metres ahead. Your van is fully loaded with passengers. The weather is clear and dry.

No, you should not overtake. The solid white line on your side means overtaking is prohibited. Even if the line were broken, the curve ahead and the junction 200 metres away make overtaking unsafe because you cannot see oncoming traffic or hazards. The truck's dust and debris reduce visibility, and your van is fully loaded, which increases stopping distance and reduces acceleration. Overtaking would require crossing the solid line and entering a blind curve, risking a head-on collision. Instead, maintain a safe following distance (at least 2 seconds, more due to reduced visibility from dust), and wait for a safe opportunity with clear visibility and broken line permission.
2. What following distance should you maintain, and why?
Read the worked answer
Maintain at least a 3-second gap because the truck is emitting dust and debris, which reduces visibility and reaction time. In dry, clear weather, the 2-second rule is minimum, but with reduced visibility from dust, increase to 3 or 4 seconds. Also, your van is fully loaded, increasing stopping distance, so a larger gap is prudent. To check, pick a fixed object ahead; when the truck passes it, you should be able to count at least 3 seconds before you reach it. This gap allows you to react if the truck brakes suddenly or if debris causes you to slow.
