Explanation
What can cause unnecessary obstructions?
Option A: Switching off the engine while in a traffic jam may lead to blocking other motorists and this may cause an accident. One way around this is by practicing smooth starts and stops.
Option B: Slow driving without any reason is a nuisance to other road users and disrupts the free flow of traffic. It is important to move at an appropriate speed depending on the current road and traffic conditions.
Option C: Lack of fuel while stuck in traffic is preventable and leads to congestion and increased risk to individuals and other road users. This problem is solved by regularly checking and refilling the fuel tank.
