If you drive more slowly than the flow of traffic, you will most likely:

  1. Interfere with traffic and receive a ticket. ✓
  2. Improve traffic flow.
  3. Demonstrate defensive driving techniques.

Answer: A. Interfere with traffic and receive a ticket.

If you drive slower than the flow of traffic, you will most likely interfere with traffic and receive a ticket.

Why this is the answer

The handbook says you must slow down for heavy traffic or bad weather, but you should not block normal, reasonable traffic flow by going too slowly. It also states that driving faster or slower than the speed limit may get you cited. So holding up the cars around you both disrupts the flow and puts you at risk of a ticket. If you do want to drive slower than other traffic, the handbook tells you to use the right lane and let faster drivers by.

Why the other answers are wrong

Remember it

Plan to keep up with the flow; if you want to go slower, stay in the right lane and let others pass.
