What must you do if you're driving in adverse conditions, such as snow or ice?

Answer: C — Slow down and increase your following distance

When driving in adverse conditions like snow or ice, it is essential to slow down and increase your following distance. This is crucial because reduced visibility and traction can significantly affect a vehicle's performance. By slowing down, you give yourself more time to react to sudden changes, such as other vehicles stopping or losing control. Additionally, increasing your following distance allows for a greater buffer zone between your vehicle and others. In slippery conditions, vehicles require more time to stop, so a longer following distance helps prevent collisions. Maintaining a safe following distance can give you the opportunity to react to potential hazards without risking an accident. Overall, adjusting your speed and increasing the distance to the car ahead are vital practices for safe driving in challenging weather conditions.
