Saskatchewan SGI Driving Practice Test

How far in advance should you signal when changing lanes?

1. At least 30 meters

2. At least 75 meters

3. At least 100 meters

4. At least 150 meters

The correct answer is: At least 100 meters

When changing lanes, signaling at least 100 meters in advance is essential for a few reasons. First, this distance gives other drivers ample time to notice your intention to change lanes and adjust their driving accordingly. Adequate signaling helps create a safer driving environment by reducing the likelihood of sudden movements or collisions that can occur if other drivers are unaware of your plans. In urban settings, where the speeds are usually lower, a shorter signaling distance may sometimes be appropriate, but maintaining a standard of 100 meters is generally advisable to accommodate various driving conditions and speeds. This practice enhances overall road safety and promotes defensive driving techniques that are crucial for preventing accidents.
