When travelling slower than the other traffic, you should

  1. keep well to the left-hand side of the roadway.
  2. keep well to the right-hand side of the roadway. ✓
  3. signal other drivers to pass you.
  4. drive in the middle of the roadway.

Answer: B. keep well to the right-hand side of the roadway.

When you are travelling slower than the flow of traffic, keep well to the right-hand side of the roadway.

Why this is the answer

The handbook says that driving slower than the traffic flow raises your chance of a collision with vehicles behind or beside you, because other drivers get impatient, follow too closely or try to overtake, and may cut in after passing. When you can't keep up with the flow, you must travel in the right lane. Staying to the right keeps slower vehicles out of the way of faster traffic and matches that rule.

Why the other answers are wrong

Remember it

Think of it this way: slow traffic belongs on the right, so faster drivers pass you on the left.
