Which of the following is NOT a cause of skidding?

The choice indicating fuel efficiency is not a cause of skidding because fuel efficiency relates to how well a vehicle uses fuel, rather than factors that affect traction and control on the road. Fuel-efficient driving techniques generally involve smooth acceleration and braking, which can actually help maintain better control of the vehicle.

In contrast, excessive speed can lead to skidding because it reduces the driver's ability to react to road conditions and decreases the traction between the tires and the roadway. Coarse or abrupt steering can cause a loss of traction, especially if the tires are turned suddenly while traveling at high speeds, leading to skidding. Similarly, harsh acceleration can overwhelm the tires' grip on the road, particularly on slippery surfaces, further increasing the risk of a skid. Understanding these distinctions helps in developing safe driving behaviors that prioritize control and stability, especially in emergency situations.
