Question

the posted speed limits show: the minimum legal speed limit the exact speed at which you must travel to avoid a ticket the maximum safe speed under ideal road and weather conditions the maximum safe speed under all road conditions

Explanation:

To determine the correct option, we analyze each choice:

• "The minimum legal speed limit": A speed limit sign like 65 typically indicates a maximum, not minimum, so this is incorrect.
• "The exact speed at which you must travel to avoid a ticket": Speed limits are not exact requirements; slight variations are allowed, so this is wrong.
• "The maximum safe speed under ideal road and weather conditions": Posted speed limits are set for safe travel when roads and weather are good (ideal), as conditions like rain or snow would require lower speeds. This matches.
• "The maximum safe speed under all road conditions": Road conditions vary (e.g., icy, wet), and the speed limit isn't safe for all conditions. So this is incorrect.

Answer:

The maximum safe speed under ideal road and weather conditions
