Which of the following actions is illegal while driving in Ontario?

Using your cellphone without hands-free mode is illegal while driving in Ontario because it significantly increases the risk of distractions that can lead to accidents. The law is designed to ensure that drivers' attention remains focused on the road and that their hands are on the steering wheel. When a driver holds a cellphone in their hand to talk or text, they compromise their ability to control the vehicle safely.

In contrast, using a hands-free headset is permitted under Ontario law, as it allows drivers to maintain hands on the wheel while engaging in conversation. Eating while driving, while not ideal, is not specifically legislated against unless it leads to dangerous driving behavior. Checking maps on your phone is also regulated; if done while stationary or using hands-free features, it may be acceptable, but actively managing a device while driving is prohibited. Thus, the legislation prioritizes the safety of drivers, passengers, and pedestrians by restricting handheld cellphone use.
