Under Michigan's basic speed law, you should adjust your speed based on which factors?

• A. Weather, traffic, and road conditions.
• B. Only posted speed limits.
• C. Your driving experience.
• D. The color of your vehicle.

Answer: (A)

In Michigan, the basic speed law means you must drive at a speed that is reasonable and prudent for the conditions you’re actually facing. The key factors to consider are weather, traffic, and road conditions. If rain, snow, ice, fog, or wet pavement reduces traction or visibility, you slow down accordingly. Heavy or unpredictable traffic, pedestrians, or construction zones require reducing speed to maintain a safe following distance and time to react. Road features like sharp curves, hills, or poor lighting also influence what’s safe. The posted speed limit is not a guarantee of safety in every situation; you may need to go slower than the limit to stay safe. The color of your vehicle or your personal driving experience aren’t relevant to this law.
