why is it advisable to avoid driving between midnight and 6 a.m.?
○ driver alertness is significantly decreased during these hours.
○ traffic laws are not enforced during these hours.
○ gasoline costs are higher at night.

Explanation:

To determine why avoiding driving between midnight and 6 a.m. is advisable, we analyze each option:

• "Driver alertness is significantly decreased during these hours": Fatigue and reduced alertness at night/morning (midnight - 6 a.m.) is a well - known factor increasing accident risk, making this a valid reason for avoiding driving.
• "Traffic laws are not enforced during these hours": There's no general rule that traffic laws are unenforced at these hours, so this is incorrect.
• "Gasoline costs are higher at night": Gasoline pricing doesn't typically have a consistent increase at these hours related to driving advisability, so this is incorrect.

Answer:

A. Driver alertness is significantly decreased during these hours.
