Saskatchewan SGI Driving Practice Test

When can you enter an intersection with a yellow light?

1. When traffic is heavy

2. When you are unable to stop safely before entering the intersection

3. When you expect the light to turn red

4. When you have the right of way

The correct answer is: When you are unable to stop safely before entering the intersection

Entering an intersection with a yellow light is permissible primarily when you are unable to stop safely before reaching the intersection. This indicates that the yellow light serves as a warning that the signal is about to change to red, but it does not require an immediate stop if you are already too close to the intersection to do so safely. The rationale behind this is to prevent sudden and potentially dangerous stops in the middle of the intersection, which could lead to collisions or create an unsafe situation for the vehicles behind you. Stopping safely means assessing your speed and the distance to the crossing; if stopping could endanger you or other road users, proceeding through the intersection during a yellow light may be the safest option. It's important to exercise caution and still ensure that it is safe to proceed. The other options suggest reasons for entering an intersection with a yellow light that do not align with traffic safety rules. Heavy traffic, anticipating the light change, or having the right of way do not justify entering on yellow, as these scenarios do not consider the established traffic signal rules aimed at maintaining order and safety on the roads.
