Should you always drive slower than other traffic?

  1. No, you can block traffic when you drive too slowly. ✓
  2. Yes, it is a good defensive driving technique.
  3. Yes, it is always safer than driving faster than other traffic.

Answer: A. No, you can block traffic when you drive too slowly.

No. You should not always drive slower than other traffic, because driving too slowly can block normal and reasonable traffic flow.

Why this is the answer

The handbook says you must drive slower in heavy traffic or bad weather, but it also says you should not block normal, reasonable traffic flow by driving too slowly. It notes that driving faster or slower than the speed limit may get you cited, and if you choose to drive slower than other traffic, you should use the right lane. So slower is not automatically the best or safest choice in every situation.

Why the other answers are wrong

Remember it

Match reasonable traffic flow; if you go slower, keep to the right lane.
