Ontario MTO Truck Knowledge Practice Test

A broken yellow line to the left of your lane means?

1. No passing allowed

2. Safe to pass when clear

3. Pass only if speeding

4. Passing zone ends

The correct answer is: Safe to pass when clear

A broken yellow line to the left of your lane indicates that it is safe to pass when the road is clear. This marking suggests that drivers are permitted to overtake vehicles in the lane next to them, provided there is no oncoming traffic and it is safe to do so. The presence of a broken line means the area is designated as a passing zone, allowing for the maneuver as long as it can be carried out safely without exceeding speed limits or creating unsafe conditions. In contrast, a solid yellow line would indicate that passing is not allowed, while additional context such as the absence of lines would not provide specific instructions regarding passing. The stipulation about passing “only if speeding” is not a valid interpretation of the broken line's meaning, as safe driving practices prioritize legality and safety over speed. Lastly, a broken yellow line does not indicate that a passing zone ends but rather signifies that it is permissible to pass under the right circumstances.
