When overtaking and passing another vehicle, what should a driver always do?

When overtaking and passing another vehicle, the correct action is to keep well to the left. This practice is essential in ensuring safety on the road. Keeping to the left allows for a clear passage when overtaking, providing more space for both the overtaking vehicle and the one being passed.

In Ontario, as in many other regions, maintaining this clear distance is crucial to prevent accidents. By moving to the left, drivers can better gauge the distance and speed of both their vehicle and oncoming traffic, which reduces the risk of collision. It's about ensuring that when you do overtake, you can do so in a manner that is safe and legal, as you are expected to drive on the right side of the road.

The other options do not align with safe overtaking practices; for example, speeding up significantly may lead to reckless driving and loss of control, while sounding the horn is typically unnecessary and can distract or startle other drivers. Keeping well to the right is also not advisable because this would obstruct the overtaking process.
