UK Driving Theory Practice Exam

Coasting is the act of driving a vehicle without pressing on the gas pedal, allowing the vehicle to slow down gradually due to air resistance and friction from the road surface. While it may seem like a simple and efficient driving technique, coasting actually has a couple of major disadvantages. Option B is incorrect because coasting does not directly affect fuel consumption or tire wear. In fact, by gradually slowing down instead of abruptly braking, coasting can actually help save fuel and reduce wear on tires. Option C is also incorrect because coasting does not damage the engine or clutch in any way. However, option D could potentially be seen as a disadvantage, as coasting may reduce the effectiveness of air conditioning since the engine is not running consistently at a higher speed. Option A is the best answer because coasting can reduce steering and braking control, making it less safe for the driver and other vehicles on the road. When coasting, the driver has less control over the speed and direction of the vehicle, potentially leading to unsafe driving situations. Therefore, while coasting may seem like a convenient driving technique, it actually has some potential risks and disadvantages that should be considered when behind the wheel.
