What should you avoid doing on slippery roads to maintain vehicle control?

Answer: D — All of the above

When driving on slippery roads, maintaining control of the vehicle is crucial for safety. Each of the actions mentioned can significantly affect vehicle stability and handling. Braking too hard can lead to skidding, as sudden or excessive braking on slick surfaces often causes tires to lose traction. This can make it difficult to steer or stop effectively, as the vehicle may slide uncontrollably. Accelerating too hard can also cause a loss of grip. If the wheels spin too quickly without gaining traction, this can lead to skidding and further loss of control. Smooth and gradual acceleration is key to maintaining stability when traction is compromised. Following too closely is dangerous in slippery conditions because it reduces the time and space to react if the vehicle in front suddenly needs to stop or slows down. On slippery surfaces, stopping distances are longer, and being too close can result in a collision if the driver cannot respond in time. Thus, avoiding all these actions—braking too hard, accelerating too hard, and following too closely—is essential for maintaining control of the vehicle on slippery roads, making "all of the above" the correct answer.
