This sign means?

- Flashing lights on the arrows show the direction to follow ✓
- Left turn only
- Right turn only
- Do not turn right
Answer: A. Flashing lights on the arrows show the direction to follow
This sign means the flashing lights on the arrows show you the direction to follow.
Why this is the answer
The handbook lists this meaning among the common temporary condition signs you will meet on Ontario roads, alongside construction and roadwork warnings. So the flashing arrows are there to point you toward the path to take, which is how you should read the sign. It is a direction to steer by, not a statement about which turns are allowed or banned. The passages about flashing yellow beacons also describe flashing lights as something that warns you to drive with caution, which fits a sign that guides you past a temporary condition.
Why the other answers are wrong
- B. Left turn only — A left-turn-only rule would be a regulatory direction, and nothing in the passages says this sign restricts you to turning left.
- C. Right turn only — The passages never describe this sign as limiting you to a right turn; its job is to show the direction to follow, not to allow a single turn.
- D. Do not turn right — A ban on turning right would come from a regulatory sign giving a direction that must be obeyed, and the passages do not list this sign as one of those.
Remember it
Treat flashing arrows as a moving instruction: they point at the way through, so follow where they aim rather than looking for a turn rule.
