Final answer:
The posted speed limit of 55 mph allows driving conditions to determine the appropriate speed, not always driving at 55 mph.
Explanation:
A posted speed limit of 55 mph means that you may:
- Drive 55 mph only under normal or favorable driving conditions.
- Ignoring the speed limit and believing highway patrol officers don't care is incorrect and unsafe.
- Driving 65 mph between sunset and sunrise violates the posted speed limit.
