Question

when roads are slippery, you should: decrease the distance you look ahead of your vehicle stop and test the traction of your tires while going up hills avoid making fast turns and fast stops refrain from driving at all costs

Explanation:

When roads are slippery, fast turns and stops can cause loss of traction (due to reduced friction), leading to skidding. Decreasing look - ahead distance is wrong (should increase to anticipate hazards). Stopping on hills to test traction is unsafe (can cause sliding back). Refraining from driving at all costs is extreme (not always necessary). So the correct action is to avoid fast turns and stops.

Answer:

Avoid making fast turns and fast stops
